Homeowners hear all about the amazing benefits of metal roofing, but roofing experts can be pretty stingy on the details sometimes. There are many types of metal systems available on the residential market, but not all of them are created equal. If you’re thinking about switching to a metal roof installation, you’ll want to start your search with corrugated roofing!

Today, we’ll be looking into this durable and very cost-effective style of metal roofing. Let’s start with the corrugated metal roofing pros and cons, then look into comparisons with other solutions. By the end of our discussion, you should have an idea whether or not corrugated could be right for your home! Let’s dive in.

Is Corrugated Metal Roofing Good?

When you first become a homeowner, your relatives probably warned you not to go with the cheapest building materials for improvement projects. As the entry level solution for metal roofing, many homeowners are intimidated by the lower price range of corrugated panels, which is only natural. However, this style of metal roofing offers several enticing benefits for adopters, including:

  • Long Roof Life Expectancy
  • Exceptional Energy Efficiency
  • Extremely Capable Weather Protection
  • Low Maintenance Requirements
  • Simple Installation
  • and More.


How Long Will a Corrugated Metal Roof Last?

Metal roofing (in general) comes with a very long lifetime. Corrugated metal roofing can last as long as 60 years without needing replacement. That’s three times the average life expectancy of an asphalt shingle roof! Keep this fact in mind when we discuss pricing later.


Does Corrugated Metal Roofing Rust?

Have you ever seen a plumber hydro jetting through a metal pipe, when suddenly they realize the entire line is covered in rust? Corrosion is a natural concern when it comes to metal roofing, but modern manufacturing techniques allow us to capably address this problem. If your corrugated paneling is made from steel, there’s a chance the materials have already been dipped in a protective coating. When that coating is zinc, it’s known as galvanized steel. Galvalume steel is steel that has been coated in aluminum.

Speaking of aluminum, that’s another material you can select for your corrugated panels. This reflective material is naturally immune to rust, which is why you’ll often see it in salty-air places like the Texas coastline. If you don’t want to worry about rusting problems, aluminum panels could be your best choice.


How Much Does it Cost to Install Corrugated Metal Roofing?

Corrugated metal is typically priced per square, which is another way of saying 100 square feet. While price varies based on the material used (steel vs. aluminum), gauge (thickness), and style, you can anticipate a price range of $75 – $600 per square. Of course, the upper price limit will continue to climb if you add finishes, specialized paneling, and other additions.

When you contrast that range with that of asphalt shingles ($70 – $100 per square), corrugated panels appears to be much more expensive. However, you must remember that metal roofing also boasts three times the life expectancy of shingles. Once you weigh this factor, you’ll find the two materials are very competitive.


Corrugated Metal Roofing vs Standing Seam

All these facts lead us to the big question: how does corrugated stack up against other solutions in metal roofing? There are several points of comparison for us to examine when we compare corrugated metal with high end metal solutions, especially standing seam. These include:

  • Price Difference: Standing seam may cost up to 3x as much as corrugated.
  • Installation: Standing seam comes with higher installation costs and a more complicated process.
  • Maintenance: Corrugated panel fasteners have to be tightened every 10 years.
  • Waterproofing: Standing seam overlap creates stronger waterproofing.
  • Thickness: Standing seam panels are slightly thicker (thus stronger).

Overall, standing seam metal roofs are clearly more effective in terms of protection. However, your budget will ultimately determine whether that added defense (and reduced maintenance) is worth the higher price point.
