Corrugated metal and standing seams are two popular roofing options. They have the same benefits as other metal roofs, including energy efficiency, eco-friendliness, and durability. While they are excellent choices, there are a few differences in style and performance. Here are a few things to know when comparing these two roofing styles.
What Is Corrugated Metal?
A corrugated metal roof uses a roll-formed metal sheet, which has been formed into a panel. These panels are usually wavy and rounded. Corrugated metal usually means any metal with ridges and grooves. This type of roofing is affordable and lightweight, making it a durable option that is easy to install. Many roofers use corrugated metal as a replacement for asphalt shingles. Corrugated metal can be used for both residential and commercial roofs.
Pros and Cons of Corrugated Metal
There are several benefits and disadvantages to corrugated metal. One of the pros is that it is an affordable metal option. It has a price comparable to asphalt shingles, costing about 50 percent less than a standing seam roof. In addition to that, corrugated metal roofing panels are easy to install, requiring less labor for a new or replacement roof project.
Unfortunately, there are a few cons to this type of roof. Many metal roofs do not require maintenance other than a yearly inspection. However, corrugated roofs have fasteners exposed to outdoor elements. You will have to check the fasteners to ensure they don’t need to be replaced or repaired. These roofs can develop water leaks over time. Once again, the fasteners can loosen, allowing moisture to penetrate the surface.
Corrugated metal panels can be thin. These panels are usually made with 26 to 29 gauge metal, the thinnest on the market. Thin metal is less able to withstand hail storms or high winds. These metal panels cannot be used on a low-slope roof. They need a minimum slope of 3 inches to 12 inches. If you have a lower pitch, you need to look at other options.
What Is Standing Seam?
The standing seam metal roof uses panels that lock together with a concealed fastener. These roofs have a raised seam that rises over the flat surface. Professional installers can use this technology on roofs and walls, but roofs are a more common application. The fasteners are hidden under raised seams, creating a smooth surface. The panels can also be attached with a clip or to the roof’s decking. In either case, all of the fasteners are hidden from view.
Pros and Cons of a Standing Seam Roof
A standing seam roof does have a lot of advantages. These roofs are less likely to leak due to the design of the fasteners. Since they lock together and are hidden, this roof will not have issues with moisture damage. As you can guess, there are no exposed fasteners. You will not see any of the fasteners on the roof’s surface. The fasteners are never exposed to UV rays, moisture, wind, or other weather elements that can lead to damage.
Standing seam roofs are made with technology designed to perform to higher standards. As a result, they are tested for water penetration, impact resistance, wind uplift, air leaks, and fire resistance. These roofs are built with materials designed to last for many years. Some metal roofs can restrict the natural contraction and expansion process. A standing seam metal roof allows the panels to contract and expand since they are not double pinned like other metal roofing systems.
There are a few disadvantages of these systems, and you need to consider them before installing a standing seam roof on your home. These roofs are expensive, and it can be a big drawback for many people. Depending on your roof’s size and complexity, it can be a costly option for your home. Along with that, standing seam roofs do require labor-intensive installation. These panels will have to be formed with an on-site roller or at a production facility. Its clips also need plenty of space to be correctly aligned and seamed together.
Corrugated Metal vs. Standing Seam
With the pros and cons of these roofs in mind, here are a few more points to help compare corrugated metal and standing seam. The cost of these roofing options is quite substantial. Corrugated metal roofs are comparable in price to an asphalt roof. The cost of a standing seam roof is twice as much as the corrugated option.
Corrugated roofs use exposed fasteners, making the installation process faster, cheaper, and easier. However, these fasteners are more prone to leaks. The installation process is complicated with a standing seam roof, leading to higher labor costs. You also need a professional roofer to ensure the job is done correctly.
All metal roofs are known for their durable qualities. They can hold up to the weather better than an asphalt roof. With hidden fasteners, standing-seam roofs are less prone to wind uplift, rust, and leaks than corrugated ones.
Finally, the appearance is different between these two roofs. A standing seam roof has a modern and smooth look. They are also mostly flat except for the vertical seams that run up and down the roof. Corrugated metal roofs have a wavy appearance with their exposed metal fasteners. Both options come in a variety of colors.
Choosing the Right Roof for Your Needs
With these pros and cons, you can decide whether a corrugated metal or standing seam roof is the best option for your home. Standing seams are durable, but they cost more than corrugated metal ones. Corrugated metal is priced comparable to an asphalt roof, but they don’t have a smooth appearance. Compare those options to find the best fit for your next roofing project.
