Warning: Metal Roof Issues You Need to Know About

Metal roofing has become a popular option for residential and commercial structures in recent years.

While there are more than a few benefits with this material, there are also potential metal roof issues to be aware of before having one installed. Understanding the main issues can help mitigate problems and know when to call for professional service.

Keep reading to learn what those issues are.  

The Roof Is Loud When It Rains

This is true—metal roofs can be loud when it rains.

However, this is only an issue when roofing isn’t installed properly.

The truth is that metal roofing can be installed “fast and dirty” like virtually any other construction job (and a common side effect of this method is excess noise).

However, when you find a roofing company that knows how to install this roof properly, sound-dampening effects are achieved with the installation of a quality underlayment and insulation.

Remember, though, just like anything else, not all dampening products are the same. There are several products to choose from, like synthetic underlayment which is referred to as a “game-changer” because of its long life and durability. 

Leaks in the Roof

Leaks are one of the most common issues that property owners experience with metal roofs. Usually, this is due to poor installation

During installation, punctures and gaps may occur, which makes it more likely a leak will occur, too. And, of course, over time, leaks get bigger. If you notice your roof leaking, you need to address it right away.

Failure to do this will cause the problem to spread and bring even more damage.

Oil Canning

Oil canning is visible waviness in the flat areas of your metal roofing. The technical name for oil canning is elastic buckling or “stress wrinkling.”

This problem can occur with any type of metal panel, including copper, zinc, aluminum or steel and results from the metal being over-stressed and no longer able to maintain a flat form.

Oil canning is considered a hot topic in roofing today because it’s so difficult to measure and define. There are a few reasons why oil canning may occur, which include:

  • Overproduction and extreme pressure during metal coiling
  • Improper storage, handling or use
  • Changes in the original form of the structure causing tension or movement
  • Insufficient space for thermal contraction and expansion
  • Frequent stress

There are ways to reduce the chances of oil canning. For example, you can buy a thicker metal or use a ribbed roller to reduce the flat space on the panel. Another option is to choose a matte or low-gloss finish, which reduces reflectivity.

Strength of the Roof

What happens if you need to get on the roof to make repairs?

Many people assume that a metal roof cannot be stood on—but it’s not because of the material.

The support of the roof doesn’t come from the material used. Instead, it comes from the finishing and the framing right under the surface. If you have a solid deck, you can walk on any flat part of the metal roof panel.

There are also many metal roofing panels that are textured, which means you have some traction when you walk across them.

Blow-Offs

A blow-off may occur if the roof is not installed properly.

If the flashing isn’t attached well, for example, laps and open seams can result in portions of the roof blowing off.

You can avoid this by making sure that you have your roof installed by commercial roofing professionals and checking for issues regularly.

By preventing blow-offs, you can save a lot of money on repairs.

Scratching and Scuffing

Similar to anything else with a paint system applied to it, metal roofing may be subjected to scuffing or scratching.

Trustworthy commercial roofers will take extra precaution to make sure the coil isn’t scratched during the slitting process, making sure to handle panels and coils with care.

Ponding Water

Another cause of problems with metal roofing is ponding water.

If water begins to collect on the roof, it results in unnecessary pressure and may lead to leaks or other issues.

If you maintain your roof and remove any puddles of water, especially after it rains,you can avoid more serious issues.

Metal Roof Issues: Now You Know

If you are concerned with metal roof issues, there is one way you can feel confident—hire a quality contractor for the installation of your roof.

By doing this, you can prevent issues from occurring at the onset.

Keep in mind, though, that even with proper installation, problems may occur from time to time. Regular maintenance can help stave off several potential issues.
