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.

• Preparation: Remove all contaminants like laitance and sealers from the  surface. This step  is critical if the application is going to be successful in penetrating and adhering to the surface.  Mechanical application is recommended for a through layer of the paste that can penetrate the concrete pores.
• Repairs: Make all repairs of cracks and joints using a polyurea-based material that has superior flexibility and fast curing speed.  To extend the material, use a sand or pea gravel as a filler for large cracks, holes, and spalls. 
• Primer:  Using the manufacturer’s recommendation of primer, squeegee on the number of coats in the thicknesses stated. A colorless primer coat or a tinted coating an be used. 
• Bed Layer:  Allow the primer two to four hours to dry, depending on the temperature, but you should be able to walk on it as a test its ready. If this is for a garage floor or a flooring with metallic or Medici flooring systems, you’ll need two coats and now is the time to apply the second coat primer. 
• Topcoat: With the second coat dry and cured, vacuum the flooring to remove any loose material then apply the top coat using a flat blade squeegee.

Can polyurea be applied over epoxy?

An  existing garage floor with a two-part coating like epoxy, polyaspartic, polyurea, or polyurethane, should be adaptable to applying a polyurea coating without any issues or problems.  Refer to the manufacturer’s instructions and follow the recommended steps for accurate process. 

Is polyurea better than epoxy?

When it comes to flooring in your home, the garage floor is usually overlooked, especially when it comes to applying a coating. Now after living there a few years you’re ready to sell and noticed that the garage floor looks pretty bad. Perhaps a new coating will improve it and help get the asking price for your house. Question you have now, should you go with an epoxy coating or a polyurea coating? Let’s look at the specs of both: 

• EPOXY COATING: Epoxy is not a paint product, but rather, a shield material for flooring, acting as a barrier. Epoxy coatings comes in different thickness that bond with concrete, is durable and moisture-resistant. There are some drawbacks as with any product, one being over time, it drastically fades if exposed to the sun. Epoxy coating isn’t as flexible as some like their garage floor coating, so it may need frequent repairs and will need regular maintenance to take care of any abrasions, and it isn’t good in freezing temperatures.  Epoxy coating is vulnerable to blistering and bubbling, which weakens the material. 
• POLYUREA COATING: Polyurea coating is the result of chemical reaction and creates a beautiful, waterproof coating that is flexible and impact-resistant. It withstand fluctuating temperatures, doesn’t crack, peel, or fade. Polyurea coating is a twenty time stronger material that cures fast. Because it does cure quickly, it is recommended to be installed by a professional contractor with manufacturer training. 

Can polyurea be painted?

In general, spraying a 100% acrylic latex house paint will work well with a polyurea coating. It is recommended to do apply the paint within 24 hours of applying the polyurea coating.

How long does polyurea last?

A Polyurea coating that has been applied by a trained contractor will last up to ten years depending on the environment. With ability to stand up to 5,000 psi, polyurea coating is a durable coating that can be customized  and cures within seconds of application.

With all the information we’ve provided in this piece, let’s discuss what polyurea coating pros and cons are:  

The Pros:

• High tolerance to heat 
• UV-resistant
• Abrasion, chemical, and scratch
• High-gloss finish.
• Impact resistant
• Waterproof resistant
• Flexible, doesn’t crack or peel
• Fast curing

The Cons:

Today, there are several metal roofing types to choose from that will match any architectural style. We’re going to review the different types of metal available for roofing, but your location and the environment can be a deciding factor which one is best for you. 

Copper Metal Roofing 

It has been around forever and is found in all corners of the world, copper is referred to as the grandfather of all metal roofing. It has a long-life span, up to 200 years or longer, it is 100% recyclable, and because it is soft, it is quiet. However, as an extremely soft metal, it may not be the right metal roofing for an area prone for hailstorms. 

Aluminum Metal Roofing 

Aluminum metal roofing is equivalent to a Dune Buggy when it comes to roofing. Seal off any essentials, install a roll cate, and you’re ready to go. Aluminum metal roofing corrosive resistant and durable, like a dune buggy, perfect for coastal residence. It is expensive to have installed and with a high strength-to-weight ratio can make it a thin material for some areas.

 Zinc metal is amazing and as it patinas, it heals any scratches. A lifespan of more than 100 years, this natural property is popular among commercial structures. It is easy to form and manipulate in different chapes, although for residential use, it isn’t one of the most appealing metals. 

Steel Metal Roofing

Steel is an alloy that is used in any building aspect you can imagine. Steel metal roofing is a common material for commercial properties now and is spreading into the residential areas. It is easily available, and the low cost and recyclability makes it a popular choice.

What is a roof restoration?

The basic definition of restoration is the process of restoring an existing item and making it like new. People restore boats, cars, houses, and even commercial roofing. When we are speaking about roof restoration, removing the existing roof is not required. A roofing contractor simply adds to the existing roofing, extending the lifespan and giving your building the protection as a roof is intended. 

What is involved in roof restoration?

A roof restoration is done by applying a highly-engineered roof coating on an existing roof deck. This restores the existing roof to a like-new condition and delays the need to get a completely new roofing job by several years.
