What types of metal are best for a metal roof installation? 

The most common type of metal for metal roof installation on homes and commercial properties include: 

• Aluminum
• Copper
• Galvalume
• Stainless steel
• Zinc

Corrugated galvanized steel may be the most common and durable. This metal roofing is typically a steel sheet that is coated with zinc and rolled into corrugated sheets. Sometimes, aluminum, zing, or silicone-coated steel types of metals are used for a metal roof installation. 

What goes underneath a metal roof?

There are three types of underlayment commonly included with a metal roof installation. It is installed before the sheets of metal and is attached to the roof deck or sheathing. The three types of underlayment are: 

• Felt
• Self-adhering membrane
• Synthetic sheet

The professional roofing contractor you choose will advise you which of these is the best for your home or commercial structure metal roof installation.  Do you need plywood under a metal roof?

Yes, it is recommended with a layer of roofing felt or other underlayment material on top. 

Can a metal roof installation be done over asphalt shingles?

Technically, yes it is possible for a metal roof installation to be over an existing asphalt shingled roof if permitted by local building codes. An experienced roofing contractor will get those clarifications when they quote the job. Yes, not removing the existing roofing material is a money and time saver, but the manufacturer of the metal may not honor any warranty. This should be clarified with your roofing contractor. 

How long does it take to install a metal roof?

The cost of a metal roof installation will depend on the size of the roofing surface and the type of metal being used. Other factors that can affect the cost are any repairs needed as the installation is taking place.  

What are the disadvantages of a metal roof?

While a metal roof installation is worthwhile, there are some disadvantages to having a metal roof as well, including: 

• The upfront cost.
• The noise level if proper installation with insulation is skipped.
• Contraction and expansion cause the fasteners to loosen and need replacing.
• Patching a metal roof installation will have inconsistency in color match.

What is the biggest issue with metal roofs?

A common problem with improper metal roof installation is typically when the underside hasn’t been coated prior to installation. This corrosion occurs when water molecules are trapped between the panel and the insulation or underlayment. The corrosion causes the metal to weaken, rust forms, and the roof becomes weak and is likely to leak. 

Is a drip edge necessary on a metal roof?

Yes, a drip edge is needed on a metal roof installation. This is a layer of protection from the possibility of wind damage, common with storms in this area, by creating an overlap between panels that keeps the panels from uplifting.

Should you use a vapor barrier under a metal roof?

Yes, a vapor barrier should be included with a metal roof installation to keep water from being trapped inside the wall. When water gets trapped, it produces moisture, leading to mildew, mold, and rot as well as minimizing the thermal performance. 

Does a metal roof need an air gap?

Yes, a metal roof installation should have an air space underneath to help with energy savings year-round. The recommended air gap is no less than half an inch, the more gap, the better the ventilation. This has been shown to provide 97% result in radiant heat for commercial or residential structures. 

In a metal roof installation, are furring strips necessary?

If the metal roof installation is over existing roofing material like asphalt shingles, furring strips are necessary because of the thermal contraction and expansion. On an asphalt shingle roof, without the furring strips, the asphalt granules rub the metal, causing corrosion and rust. Additionally, furring strips will provide additional air ventilation. 

Topping It Off

A metal roof is more than just an aesthetic roofing material for homes or commercial structures. It provides fire resistance and energy savings and can be a bonus of a property value increase. Additional benefits include: 

• Proven lifespan expectancy of 50+ years.
• Beautiful colors and styles for homes and low-profile commercial structures.
• Provides maximum wind resistance.
• Fire resistance.
• Energy efficient, ideal in hot summers.
• Low weight eases the strain on the structural integrity.

These are positives in a metal roof installation that should be considered when comparing the pricing and warranty with other roofing materials.

1. The Durability

Aluminum roofing is exceptionally durable which gives it a long lifespan. How long will an aluminum roof last?  The lifespan of aluminum roofing is typically fifty years, even longer in some cases. Even after years of exposure to the elements, hailstorms, hard rains, high winds, ice, snow, and the constant UV sun rays, it doesn’t rot or rust and is almost impenetrable.

2. The Flexibility

Aluminum is a malleable material that provides flexibility when used for aluminum roofing.  That malleability provides the flexibility to be shaped into different designs and forms like shingles, panels, standing seams, or tiles.

3. Lightweight

Aluminum roofing is the lightest of all options in metal roofing and can provide the same level of protection as copper or thick steel roofing. This is because of the ratio in its strength-to-weight ratio, but it is one of the easiest materials to install. 

4. Heat Reflection

Metal roofing is a great heat-reflecting material, and aluminum roofing is an exceptionally energy-efficient material for roofing homes or businesses. The indoor temperature is regulated better to keep the interior cooler during hot summers here in Spring, Texas, and warmer in the winter, all of which keep monthly utilities low. 

5. Eco-Friendly 

Aluminum roofing is a common metal that is made from recycled metal and can be recycled when it has completed its life as a roof. 

6. Fire Resistant

Aluminum roofing is a fire-resistant roofing material with a Class A rating because of its additional fire-retardant coating.

7. Corrosion Resistant

Aluminum roofing is resistant to corrosion, a key benefit in areas where the weather can have a high level of moisture.

How is Aluminum Roofing Different From Other Types of Roofing?

Over time, asphalt roofing wears from hailstones, heavy rains, UV rays, and wind, shortening its lifespan between 12 and 15 years. Aluminum roofing will last longer under those conditions, meaning that new roofing won’t be needed as soon. 

How is Aluminum Roofing Installed? 

When aluminum roofing is installed correctly, it provides a modern, sleek appearance without any seams. The steps for installing aluminum roofing start with ordering the aluminum panels to fit in order to minimize the number of seams. The next steps include: 

Install the underlayment

• These are sheets of OSB or plywood for the roof decking. 

Close the trim ends 

• Cut, trim, and bend the ends to fit around corners. 

Fasten the eave trim

• Install the eave trim tightly to the fascia to the roof decking.

Splice the trims

• Splice where two trim ends come together so they underlap at the angles.

Snap a reference a line

• Snap a chalk line for a square reference line so the aluminum roofing panels are installed evenly.

Set the aluminum panels

• Place each aluminum roofing panel on the inside closure strip, shaped to fit the underside of the first panel. Screw the panels in place to make them watertight. 

Cover the rake edge

• With all the aluminum panels fastened, install the gable trim the secure the ridge cap with butyl tape and closure strips.

What Tools are Used to Install Aluminum Roofing? 

For correctly installed aluminum roofing that will have a guarantee and warranty on the workmanship, choose an experienced roofing contractor that has worked with aluminum. However, it can be a DIY project. The following tools are needed: 

• Essential carpentry tools
• Aviation or metal snips
• A hand seamer
• Metal Shears
• A cordless drill or screwdriver
• Personal protection equipment including gloves and goggles
• A second person to hold the ladder and hand materials

How Much Does Aluminum Roofing Usually Cost? 

The exact cost of aluminum roofing can fluctuate with the market, but in general, is more expensive than asphalt shingle roofing but less than clay or slate roofing materials. 

Does Aluminum Roofing Require Maintenance?

Keeping the debris and leaves off aluminum roofing will ensure the longest lifespan. This can be done with a soft power washing method every 18 to 24 months. Keep the gutters cleaned and in good condition to ensure that water can flow down and away from the roof and foundation. 

Experience the Benefits of an Aluminum Roof

Any structure, whether it is a business or home, is an investment that should be protected, which is what the roof does. With aluminum roofing, this level of protection is done with an aesthetically pleasing appearance that has a long lifespan and several facets of flexibility. With minimal maintenance required and the durability that aluminum roofing offers, this is a roofing material that any business owner or homeowner can appreciate. 

What is special about church roofs?

Church roofing is special because it is protecting a place of worship. It may be seen as just another structure, like the homes and businesses around it, but a church has significance to many. This is where people go to pray, watch a couple join the union of matrimony, or where we go to bid our last good-byes.  The contents inside a church are often of historic value, as well as things of monetary value. Like a home, there are furnishings, flooring, electricity, plumbing, and more.  

When we think of church roofing, we picture the steep, tall roofing with a steeple on the top. Today, though, church services are held in large metal constructed structures with flat low-sloped roofing or in strip center buildings with flat roofing. Still, no matter the type of structure and church roofing is still there for protecting a place of worship.

Why do churches have steep roofs?

There are some different opinions on the reason church roofing is typically made of a steep construction: 

• One reason references back to the Middle Ages. The church roofing and steeple were built as high as they pointed to heaven. It was believed that it protected those who worshipped inside were protected from the evil spirits that many that afflicted church buildings.
• Another opinion why church roofing is typically steep is to draw our vision upward, toward the heavens. The lofty church roofing and the high ceilings inside not only direct us to look upward but remind us there is more to life than our own everyday earthly existence.
• And another opinion of steep church roofing, it gives the structure a more significant presence and makes it easier to locate the structure. Churches were built in a time when other structures were smaller, thus the steep church roofing dwarfed the other structures, making them seem insignificant. This is the building that housed the religious thoughts of eternity and infinity.

 Do church roofs require regular maintenance?

A church structure that was constructed many years ago and still standing today is evidently a well-built, strong structure. But that doesn’t negate its need for routine maintenance and repairs.  Just like our homes, the structural strength of a church depends on the foundation of the structure and the church roofing. 

Climate, time, weather, and water do not pass over church roofing. This structure can be damaged, and the roof weakened by water leaks, wind damage, and more. However, the structure it protects often includes non-standard features, like concealed gutters, parapets, and steeples. 

These features that make a church uniquely beautiful add complexity to maintaining and repairing the church roofing. It takes more than a residential roofing contractor, the person that repairs church roofing should have specific training and skills. 

Most of any potential issues and problems with church roofing can be stopped and repaired before any severe and lasting damage happens. But, like our own home, the roofing should have regular inspections, gutter cleaning, and more to keep it healthy and safe. 

What pitch is a church roof?

Traditional church roofing has a 50/12 pitch, making it one of the most distinguished and recognizable structures. These numbers mean that the roof rises upward 50” for every 12″ inward toward the peak. A roof peach can be measured in two ways: 

• One: From the rooftop, a 12” level mark is made, and while keeping the measurement balanced and level, between the distance from the starting level point to the roof surface. 

• Two: Start by measuring from the rafter bottom, measure the pitch in the same process, but in three locations. This is the preferred method of most roofing contractors. 

How are steeples attached to church roofs?

A steeple can be constructed to stand on its own foundation, or it can be integrated into a larger structure, the church building, end wall, or sidewall frame. Many steeples on church roofing are timber-framed steeples and their bearing weight is divided into two posts on the church’s end walls and two posts on the first roof trusses of the interior.

There are different components within the church roofing’s steeple. A steeple on church roofing can be five to six stories high. A top of the church roofing is the steeple, and a top of the steeple is the spire.  Where the steeple is a turret of the church building, the spire is the top of the steeple, rising a tapered top higher. Below the spire, a church may have a lantern or some type of lighting, and below that is the Belfry where a bell is housed. At the steeple’s lowest level is the tower. 

Is there a specific type of roof churches need?

Just as it is for your own home, church roofing is a big decision for the leaders to make. There are many different aspects to consider when looking at the many choices available.  Things that must be considered in the decision are: 

• Architectural Integrity
• Aesthetics
• Energy Efficiency
• Life Expectancy
• Maintenance Expenses
• Proper Installation
• Weight to Structure
• Fire Resistant
• Weather Strong

With the investment that new church roofing can take, more church leaders are going with metal church roofing now, but why? A list of the benefits they see metal roofing providing a longstanding ROI are: 

• HEAT AND SUN: Where other roofing materials dry out in the Texas summer heat and sun, metal roofing withstands it the best. 
• WIND RESISTANCE: All across Texas, the weather can include devastating high winds. From hurricanes to tornados to ‘northerners’, roof damage is the most common result.
• ICE AND SNOW: Ice and snow are two of the worse things that church roofing must withstand. Metal roofing quickly sheds snow loads, but the insulation under the metal roofing or the ice dams cannot be skipped. 
• LIGHTNING: Research has found that metal roofing isn’t any more likely to attract lightning than other roofing materials. However, the elevation of church roofing is a concern. It is recommended that church roofing have grounding installed along with the metal roofing because of the height that the steeple and spire create. 
• HAIL: Metal roofing is known for its hail resistance, and here in Texas, that is an important consideration. 
• FIRE SAFETY: Church roofing needs to be protected from fire as much as other structures, and most metal roofing is rated at Class A, Class B, and Class C. A special underlayment is often included for specific building codes and fire classifications. 

Which metal would be most suitable for a church roof?

Aluminum metal is the most popular choice among church leaders when deciding on the new church roofing material. It is attractive, energy-efficient, lightweight, fire-resistant, rust-resistant, and weather-resistant. 

First, we’ll tell you why it is called ‘roof flashing’. There isn’t any certain reason that has been found about the terms flash and flashing origin. It is thought to be a Middle English verb that originally was ‘flasshen’, meaning to sprinkle or splash, a lead strip. Sometimes it was referred to as ‘the apron’ when installed around a chimney. 

Today, the reference of roof flashing is the strips of thing metal that is installed on a roof in areas where water can seep in around the roofing materials and roof protrusions. The metal is usually a galvanized steel but can be aluminum, copper, or stainless steel. With the understanding of where and why we have roof flashing, repairs are easy to understand their importance. 

Do I really need roof flashing?

Absolutely! As we’ve mentioned, roof flashing protects several areas of the roof components, like the chimney, skylight, and other protrusions, from water seeping in , causing damage with leaks. Roof flashing keeps the water from getting under shingles and down walls. 

Any area where water runs through a crevice or corner, there needs to be roof flashing. This is why it important to have roof flashing repaired as soon you notice a problem. With roof flashing loose or missing, water can get in around the chimney or down inside walls. Even the gutters that are made to direct water away from your home needs roof flashing, so the water runs into the gutters. 

Is roof flashing required by code?

It will depend on where you live but in most areas, yes, roof flashing is a building code requirement. You would be hard pressed to find a professional roofing contractor that tells you roof flashing is unnecessary. Even if the local building code where you live doesn’t require roof flashing, an experienced roofing contractor will insist it be installed. 

What are the different types of roof flashing?

There are two basic kinds of flashing, one being an external flashing and the second is an internal flashing. The external flashing prevents moisture from penetrating where walls intersects with the roof. The following are the different types of flashing used in most roofing jobs: 

• Continuous Flashing. Also referred to as apron flashing, is a long single piece of metal that carries water from the shingle to off the house. 
• Base Flashing. A roof feature like a chimney, requires two pieces of flashing to ensure rain will always meet a flashing surface to direct it off the roof 
• Counter Flashing. Installed opposite of base flashing, this piece completes the team for base flashing.
• Step Flashing. A rectangular shaped flashing in a 90 degrees angle is used for wall flashing in layers with multiple other pieces of the same type of flashing. This is to assure that water is flowing away from walls. 
• Skylight Flashing. This type of flashing comes with new skylight installation, but existing skylights need new flashing with new roofing. 
• Valley Flashing. Open valleys are where two roof angles come together and is a critical are to protect from leaking. When there is a need for roof flashing repairs in this area, it must be addressed immediately. 
• Drip Edges. This flashing is installed along the roof edge, allowing water to drip off without causing damage to your home. 
• Kickout Flashing. This flashing is used to bridge the gap between the step flashing and the gutter runs to direct water away from a wall and into the gutter.

What is the best roof flashing?

When you are selecting flashing for your home, the budget will be the first concern. You should choose a flashing material that is long lasting so that you won’t need to worry with roof flashing repairs. Common choices of roof flashing are:  

• Aluminum: The most popular of all materials because of the cost factor but still offers quality. 
• Copper: The most expensive of all roof flashing materials. It is strong and an eye catcher. 
• Membrane: If you’re looking for a drastic difference, this strong tape type of roof flashing give you that difference and still protect your home against the elements. 

How do you fix roof flashing?

You can always call an experienced roofing contractor for roof flashing repairs. Or you can do you own roof flashing repairs Repair corroded areas and small holes with roofing cement. Holes that are 3/4 inch diameter, place a patch of the same type of flashing material and roofing caulk. If the flashing is against the chimney or a brick wall, use a masonry caulk for sealing the gaps and joints. 

How do you add flashing to an existing roof?

Measure the area that needs flashing and purchase the like-same material as the other flashing. Using roofing cement and galvanized nails, place the flashing where needed. Step flashing along the chimney will need to be layered with the shingles. 

What can I use for roof flashing?

Steel is the most common metal for roof flashing. The roof has a clean appearance, and it is a budget friendly material. If there is room in the budget, go with the aesthetic upgrade of copper flashing. 

What is a roof restoration?

Roof restoration is a way to repair any problems and weak areas of a roof, including the fasteners, flashings, and seams, while also building a new roof surface. After a roof restoration, there is a better-protected structure against leaks and a new non-prorated warranty.

So, what makes the difference between a roof restoration vs roof replacement? With a roof replacement, the existing roof is completely removed, and a new roof is installed. You are getting two jobs done, and paying for two jobs, but with roof restoration, you’re getting a roof as good as new for half the cost, maybe less than half! 

Other reasons that going with a roof restoration on a commercial flat roof include: 

• The Cost — As we just stated, a roof restoration is a money saver, up to half as much, sometimes more. 
• The Convenience — A roof restoration takes less time than a new roof installation. With shorter time of labor, that is a money saver right from the start. There is less disruption to so that your employees, clients, and visitors aren’t inconvenienced. 
• Energy Savings — Most flat roofs have a white top coating, and while that may not be an architectural style you like, it is energy-efficient, aka, a money saver. The reflective white roof coating used in roof restoration is a great help in reflecting the sun’s UV rays and keeping the interior cooler, a huge deal in Texas summers. This puts less strain on the HVAC system and helps keep energy cost down. 
• Like New — With a proper roof restoration, the high-risk areas are reinforced to prevent leaks going forward. 

What does roof restoration include?

A roof restoration will involve a thorough cleaning of the existing roof, typically with a high-pressure spray. The removes any algae, dirt, grit, moss, and mold that has covered the roof. Then any damages are repaired, replacing any missing flashing, etc. 

Then a roof restoration coating is applied. This coating is a reflective coating that will prevent leaks and rust, extending the lifespan while saving you money and time. How long does a roof restoration last?  

The typical lifespan of a commercial roof is 20 years when properly maintained. A roof restoration can add another 15 years of life, and defer the expense of a complete replacement to work with the capital budget and your daily budget.

How much should a roof restoration cost?

A commercial roof restoration can cost between $6/per square foot and up to $10/per square foot. When you compare the cost of a new commercial roof of $25/per square foot, the immediate financial benefit is obvious. 

How do you know when to do roof restoration? 

It is important to have monthly roof inspections by your maintenance team. This enables issues to be caught and addressed before a leak starts and causes major costs and problems. In addition to the monthly inspection by your staff, a professional inspection is recommended once a year. Indications that a roof restoration is needed include: 

• The general appearance of the roof from the ground, with and without using binoculars. Look for any damage, discoloring, or worn conditions. Some buildings with a flat roof will require getting on the roof and walking around looking for things like loose or missing flashing, vents boots, etc. 
• Cracked components or separations are areas where leaks are invited. A roof restoration will seal those areas up and prevent any leaks.
• Water stains are better inspected and judged by a professional roofing contractor. They will check the membrane for any barrier or membrane issues, signs of ponding, or puddling of water.  
• Algae, mildew, and mold are organic substances, most common in moist environments or where there is a lot of trees. In addition to a roof restoration cleaning these off, it will also seal any areas where moisture is building up under the roofing surface that could be a potential leak. 

Products for Roof Restoration

What are the most common and recommended commercial roof restoration coatings and commercial roof restoration products? An experienced commercial roofing contractor that knows how to restore a flat roof will use an elastomeric base coating on the prepped roof surface. This enables them to build up a uniform thickness that is maintained throughout the roof restoration installation process. This base coat material reduces the need for the contractor to apply a primer. 

Next, a topcoat is applied that provides UV reflectiveness and stability, with moisture protection. This roof restoration coating is a bright-white membrane, ideal for reflectivity. However, at the customer’s request, a custom tint can be added. 

The equipment used in these steps may be an airless sprayer, aka spray rig, for applying an elastomeric coating connected to a hydraulic pump that will atomize coating materials. In some cases, the contractor may also use a Tank Spreader, a newer type of equipment in the roof restoration business. Another less expensive and easier to use option, but one that’s just as effective as the airless sprayer, is a Nap Roller. This is typically smaller square footage roof restorations. 

What is considered storm damage on a roof?

As a homeowner, it is important to know how to tell if a roof has storm damage. Most homeowners do not do a daily roof examination, even though it is the major component providing us protection from the elements. 

A roof is designed to hold up to strong elements like rain, snow, and winds. After a while though, a heavy storm can be too much for a roof, leaving you with storm damage roof repair needs. After a major storm event, it is recommended by experts to get a professional roof inspection because not all storm damage is visible from the ground. 

Here are three important signs that you need a storm damage roof repair service: 

• Wind Damage

With storms coming in from the coast and storms arriving from the north, there is a lot of wind, and that can do significant storm damage. So here’s a question many homeowners find themselves asking – “How do I know if my roof has wind damage?” Roof repair may include replacing missing shingles or replacing or securing metal roof flashing. 

Damaged, loose, or missing flashing can leave your roof at risk with vulnerable spots that flashing protects.  The damaged shingles where the adhesive seal has been broken can often be visualized by horizontal lines on the shingle or you may see missing granules, both leaving your roof at risk for leaks. 

• Hail Damage

Hailstorm roof damage is typically caused by hailstones that bruise asphalt shingles, leaving an indention or pock-mark on the shingles. Hail damage often leaves a distinct pattern of small round divots along the edges of the shingles, too. The flashing will show signs of hail damage with round indentations in a repeated pattern of round spots. Hail damage can also knock granules off the shingles, which can be found in the gutter runs. 

• Falling Debris

Tree branches and entire trees are victims in major storms. When they land on your roof, they can crack the shingles, or even bust through the roof. The cracked shingles are a major storm damage roof repair job; a busted hole in the roof is an entire roof replacement.

Can an ice storm damage a roof?

Definitely, and here are the three most common types of winter storm damage roof repairs are needed:

Water Damage

Freezing rain or ice can cause serious damage to a roof, with a particular problem being ice build-up in the gutter system. This prevents the melted ice and snow from draining and running to the downspouts. If the gutter or downspouts are clogged, the accumulated water gets under the shingles, refreezes, and causes the shingles to break, or the water will seep into the under decking, into the attic, and into the house. It will also seep into the walls. It only takes a few inches of water to cause extensive damage to the interior. It can affect the electrical wiring and mildew, with mold growing from there. 

Snow Damage

This part of Texas normally doesn’t see snow, but early 2021 showed us it’s possible. It only takes a few inches to cause snow storm roof damage and a need for repairs to be done. This can be an especially risky problem with a flat roof where snow can’t melt and slide off the roof. 

Often, a homeowner will use a snow shovel to remove the snow from their roof and end up damaging the shingles. Or worse, they apply calcium chloride or rock salt to the roof to melt the snow, which can inadvertently damage the shingles. This type of snow removal will usually void any warranty for the shingles and may get any insurance claim denied. 

Wind Damage

It isn’t uncommon for those high Texas winds to cause a need for storm roof damage repairs, usually because of loose shingles that are blown off with those blustery cold winter winds. Then, if there is any hail within those winds, it compounds the need for roof repair or replacement. 

Does insurance cover roof damage from a storm?

A basic homeowners insurance policy will typically help cover some storm roof damage roof repairs, including hail, lightning, and winds. What isn’t covered is any damage caused by earthquakes or floods. It is important to read and review your policy to learn and remind you what is covered and what isn’t. If you’re unclear, calling your agent to explain is recommended. 

If you own a commercial structure that has roofing issues, you may wonder, “Do I need a commercial roof specialist?” Or will any roofing contractor work?  The answer is yes. Choose a roofing contractor that specializes in both commercial roof repairs and installations. But why? 

Common Commercial Roofing Issues

That’s because a commercial roofing contractor will have a different skill set than a residential roofing contractor. They will have knowledge of the different roofing materials used on commercial structures and be more aware of the challenges and pitfalls of commercial roof repairs, installations, and maintenance. 

Major problems with a commercial structure roof can mean more than an inconvenience. It can result in a long downtime if the building has to be closed for repairs. In some cases, it can be the end of the business. That is why roof inspections and maintenance are important.

Inspections are an opportunity to find small issues and have commercial roof repair completed before they become big and expensive problems. This means you should be aware of what to look for that commercial roof repair is needed.

Leaking

Okay, it’s obvious if your showroom or any area of your building has rain pouring in, you need a commercial roof repair or replacement. However, roof leaks aren’t always noticeable – at first.  Water is the enemy of any structure; it is damaging when left unattended. So, it is important to know what secondary leaks look like and where they may appear. 

If you notice water spots on the ceiling, or you’re seeing or smelling mold, have your commercial roof professionally inspected. There is a good chance, especially if there is attic space, that the is water leaking through the roof. It could also be a plumbing leak, so if the commercial roofing doesn’t find anything, you’ll need a professional plumbing inspection. 

Blistering

Because a commercial structure in Texas is subjected to a hot sun most of the year, it is common for commercial roofing materials to blister. This allows an area for the rain to get trapped under the membrane, and when left unrepaired, it will eventually begin to create a leak. 

Shingle Damage

Like a residential structure, any shingles on your commercial structure will age, have normal wear and tear. They also will crack, curl, loosen, split, and the growth of algae and moss will begin. It is important for any roof inspection catch these things and have commercial roof repair and cleaning performed so that it doesn’t damage the roof any further, or the roof decking below. 

Roof Membrane Damage

For a commercial structure, this is the most common problem and commercial roof repairs can stop from having a major commercial roof replacement installed. Routine inspections to look for the smallest damage will keep the roof healthy longer. Blisters, cracks, splits in a commercial roofing membrane can quickly lead to big problems.

How often do you replace a commercial roof?

The climate, elements, and weather are important factors in determining the frequency of commercial roof replacement. The type of material used for the roofing is another factor, as is the quality of the material installation. Expect an average life span between 20 years and 30 years when routine inspections, proper maintenance, and professional commercial roof repairs have all been performed. 

What is the average life expectancy of a metal roof?

When it comes to commercial roofing materials, there are several choices available today. The most common commercial roofing materials are: 

• EPDM
• PVC
• TPO
• Metal

Metal roofing has become one of the most preferred choices here in Texas, partly due to its durability. That durability means a longer lifespan when it is properly maintained, and commercial roof repairs are done when needed. A lifespan for metal roofing can be up to 45 years or longer. 

How long do flat roofs last?

A flat roof with bare maintenance and upkeep or poor installation will last up to 10 years.  A commercial flat roof that is properly installed by an experienced commercial roofing contractor and has routine inspections, maintenance, and commercial roof repairs done as needed can give you up to 50 years, with the average being between 20 and 25 years. 

What is the best commercial roofing material?

It is important to analyze and research different roofing materials for your commercial structure before having a roof installation done. This isn’t a cheap investment, so you want to choose one that will give you the best care and last the longest.  Here are four of the most popular choices in Texas: 

• PVC Roofing

PVC roofing is considered one of the best flat roofing materials on the market today, even though it is one of the more expensive choices. The benefits are many, like the reinforced membrane that makes a flat roofing impact resistant. This lessens the need for commercial roof repairs!  It is a low-maintenance roofing material, a plus to any commercial structure owner. 

• Metal Roofing

Standing seam metal roofing is the ideal material for a commercial structure that has a 2-inch slope or greater. Metal roofing requires the expertise of a commercial roofing contractor that is experienced in metal roofing due to some required installation specifics. Not all commercial roofing contractors work with metal roofing.  

Once properly installed and maintained, it can last up to 45 years or longer. It is a durable roofing material for Texas with immunity to cracking. If not installed correctly and inspections not performed to look for issues, it is susceptible to leaking at the edges and seams. 

• TPO

TPO is a popular roof type for commercial roofing because of its durability and inexpensiveness. With up to a 20-year lifespan, this white-coated roofing material is great for energy saving in the hot Texas sun and has minimal maintenance requirements. 

• Modified Bitumen Roof

This is the most budget-friendly of all commercial roofing materials. Ideal for a building with a good asphalt roofing base, modified bitumen is ideal for commercial roof covering. However, it has a shorter lifespan for a commercial roofing structure, lasting a maximum of 15 years. 

What is the average cost of replacing a commercial roof?

The size of the commercial structure and the material chosen will be the two biggest factors in the cost of replacing the roof.  For a 20,000 square foot roof, you can expect to pay up to $7.50 per square foot for a single-ply roofing membrane. This includes labor and materials. 

How long does it take to reroof a building?

Again, the size of the structure and the material used will factor into the time it takes. The weather is also a big factor in roofing a commercial structure.  In general, the roof of an average-sized commercial roof can take between two weeks and three weeks.  The type of material chosen may need specific temperature ranges like cold sealed single-ply roofs 

Do cool roofs work?

Yes – a cool roof installation will provide a commercial building solar reflectance and thermal emittance. The difference between conventional roofing and a cool roof is that over 60% of the solar energy, aka the sun’s hot rays – are sent away from the building. This is because of the solar reflectance this roofing offers. 

The thermal emittance in a cool roof is what gives the roof the ability to release any absorbed heat and keep it out of the building. Combining these two things provides an SRI (Solar Reflectance Index) that measures how well a cool roof is working. 

A cool roof will reduce the urban heat island, aka local air temperature, and lower the peak demand for electricity. That minimizes, and in some cases eliminates power outages, while also reducing emissions from power plants like carbon dioxide, mercury, nitrous oxide, and sulfur dioxide.

What are the benefits of a cool roof?

There are several types of cool roofs on the market, but today, we’re going to focus on three of the most common:

1. Acrylic – A water-based coating for sloped commercial roofs. 
2. Silicone – A resin-based coating for flat commercial roofs. 
3. Urethane – A high impact coating for commercial roofs. 

Any of these three will provide a commercial structure owner the following cool roof benefits: 

• Lowers the energy cost by 20%
• Keeps the building cooler with less air running
• Reduces damage from thermal shock 
• Reduces air pollution & greenhouse emissions
• Complies with programs & standards set forth by the government
• Flexes with temperature ranges
• Bonds to existing roof surfaces directly
• Forms a seamless membrane to provide roof leak protection 
• Resists deterioration from the UV rays 
• Expands the lifespan of the roof

Probably the two most popular things for commercial structure owners is the reduction in costs for cooling the building. This helps a company’s bottom line and, by extending the lifespan of the existing roof, it also saves money by not having to replace a roof too soon. 

How much is a cool roof?

The cost of cool roofs varies from state to state, and even from city to city. The size of the building, and any specific circumstances, can affect the cost of the cool roof coating installed. Overall, the price for a low-slope cool roof can be as much as $1.50 per square foot, with a single-ply cool roof membrane costing up to $3.00 per square foot.

How much energy does a cool roof save?

When it comes to the cost of installing a cool roof, there isn’t much of a difference from the cost of a non-cool roof. That is, unless you’re converting your current roof to a cool roof. Once your cool roof is installed, you can expect to save up to twenty cents per square foot each year. That doesn’t sound like much until you do the math for a 200,000 square foot commercial structure, which is $4000.00 saved in a twelve-month period.

What is the difference between a cool roof vs green roof? 

Both a cool roof and a green roof help commercial buildings in areas that are highly populated to stay cool. With parking lots, rooftops, and streets causing the heat island effect, these two types of roofs elevate that effect, lowering the temperature by as much as seventy degrees. A cool roof reflects the heat from the sun back into the atmosphere, keeping the building cool. However, a green roof absorbs that heat, allowing it into the building. 

For example, asphalt shingle roofing s have a shorter lifespan than cedar or wood shake with the asphalt lasting on average 20 years and cedar shakes, or shingles can last 30 years or longer, depending on the weather and other contributions like tree overhanging, etc. Fiber cement shingle roofing s and other composition shingle roofing s can last up to 30 years.

What do shingles do for a roof?

The average person thinks that shingle roofing s have a cosmetic only purpose, but that isn’t their main function. Yes, even though there is a variety of designs and materials in shingle roofing s, their practical purpose is to provide a watertight, wind-resistant seal for protecting your roof. You could actually cover your roof in almost anything that served the same purpose. It doesn’t have to be “pretty”, just purposeful. 

When Should roof shingles be replaced?

Industry experts recommend having a bi-annual professional inspection. This will give the technician a chance to spot any small issues before they become a major leak problem.  This will also give them the opportunity to keep you updated on the aging and condition of your roof, allowing you time to budget a new roof. 

The underlying structure of a roof should last as long as the house itself does. However, if the roofing is done with subpar materials and shoddy workmanship, it can affect the lifespan of the roof. A general replacement schedule that roofing contractors use is: 

• Composition Shingle Roofing: 12 to 20 years
• Asphalt Shingle Roofing: 15 to 30 years
• Wood Shingle Roofing: 20 to 25 years
• Rubber Roofing: 30 to 50 years
• Metal Roofing: 50 to 75 years

These time frames can  vary with the climate exposure, heat, humidity, and severe weather conditions. The better quality of shingle roofing material, the longer the roof will last and routine maintenance and upkeep can help the roof lifespan. 

How do you know when shingles are going bad?

With homeownership, being proactive is better than reactive. There are several signs that you should be aware it may be time for new shingle roofing to be scheduled: 

#1: Loose or missing shingles

This can happen from storm damage and high winds, or your roof may simply be getting old. Regardless how it happened, when they are loose have fallen off, they aren’t doing your roof any good. 

#2: Blistering, cracked, curling, dried out

Shingle roofing s in this kind of condition needs to be replaced, and if there are several, the entire roof should be replaced. 

#3: Sagging

A sagging roof could be from a deterioration or improperly installed. It could have too much weight on it like snow or a leak has filled the ceiling with water. At this point, it has become a safety matter now and a new shingle roofing  job is needed immediately. 

#4: Dark and dirty

Dark and dirty areas of a roof are usually where asphalt granules have fell off from age or weather. Dark spots are also common with algae, lichen, and moss, which is eating away at your shingle roofing s. You can have it professionally cleaned, but if the dark areas are still there, plan on a new roof soon. 

#5: Granules in the Gutters

As shingle roofing s come loose, they fill the gutters and downspouts. When you’re seeing more in the gutters than you have been, it is time for new roofing. The less shingles, the less effective they are at protecting your roof.

#6: Exposed or loose nails

If the nails are exposed, loose, or have popped out, the holes are making your roof susceptible to penetrating water that will cause leaks and other  moisture damage. 

#7: Interior damage

If there has been any roof leaking that you haven’t noticed, you’ll find out by looking in the attic. Any water stains on the attic ceiling, moisture on the insulation, mildew, or mold is a strong indication your shingle roofing s are not doing their job. 

#8: Damaged or missing flashing

Damaged or missing flashing is an area where water can penetrate around the chimney, roof intersections or other projections on the roof. You may be able to have the flashing replaced or it may be too late.

#9: Age

When an asphalt shingled roof reaches its 20th anniversary, it is time to start budgeting for a new roof, you have maybe 5 more years left. 

#10: Energy bills have increased

This can be poor shingle roofing s, insufficient attic insulation, or insufficient attic ventilation. 

What are the different types of roof flashing?

In the early days of roofing, roof flashing was a labor intensive, time-consuming part of the roof. Birch bark and other materials were used to create roof flashing or ways to were used to redirect the water flow from chimneys and other areas prone to leaks. 

One method that was used is applying mortar flaunching, a large buildup of the substance, piled sloped around the chimney so the water would flow away from the chimney. Using shingles at an angle were another method used for roof flashing. 

Today, modern roofing uses a common roof flashing material of  flexible, thin strips of galvanized steel and there are different forms of roof flashing:

• Continuous flashing: This is the apron flashing that is one long continuous piece of roof flashing installed between a sloped roof and a vertical wall. 
• Drip edges: Typically installed all along the roof eaves under the roofing felt to keep water dripping off the roof.
• Step flashing: A ninety degree bent  rectangular piece installed in an overlap fashion at vertical walls to keep water from getting behind the walls. 
• Valley flashing: This W-shaped metal flashing is installed  on top of the roofing felt where 2 roofing angles meet creating a valley.
• Vent pipe flashing: This cone-shaped fitted metal flashing is installed into the shingles to cover areas around the vent  pipes.
• Base flashing: This flashing is installed around the base of chimneys to ensure rain is directed downwards like apron flashing. 
• Counter-flashing: Placed opposite of or above base flashing creating a team of roof flashing. 
• Cap flashing: This L shaped roof flashing lies flat to the roof, windows, and other fittings to keep water running in the opposite direction and keep it from pooling in any cracks that may be around the fitting.
• Chimney flashing: Applied around chimneys, preventing water from pooling in the gaps between the chimney and roof. 
• Saddle flashing: This roof flashing is installed around jutting beams or railing attachments.
• Skylights: This roof flashing is used for skylights that doesn’t have built-in flashing and is needed to keep from water from seeping in around the skylight and into the home. 
• Kick-out flashing: This roof flashing links the gap between step flashing and the gutter system to direct water away off the roof, away from the wall and to the gutter.

Does flashing go over or under shingles?

It depends on the type of roof flashing and the purpose it is to serve. When installed where a wall  begins, the roof flashing is installed on top of the shingles. Base roof flashing, however, should be installed under the shingles around the chimney and then secured to the roof. In some areas, like step roof flashing, it is alternated in layers of flashing, shingle, flashing, shingle, etc. 

Do roofers replace flashing?

Yes, and using a professional roofing contractor for roof flashing installation is recommended. When a new roof or re-roofing is being installed, the roofing contractor will replace the old flashing with new flashing. 

If you’re not comfortable climbing a ladder or working at high levels, calling a roofing contractor is recommended.  Having your roof inspected by a professional once a year, things like bent, damaged, loose, or missing flashing can be addressed while the contractor is on the roof. Call 832-704-2817 today for roof flashing in Spring, TX.
