Most Common Problems That Impact Metal Roofs

While asphalt shingles are one of the most popular roofing materials in the United States at large, metal roofs have continued to increase in popularity. For numerous reasons, from their longevity, durability and energy efficiency. Metal roofs are increasing in usage across the state of Maryland. However, just like with any roofing product there pros and cons.

In many instances you may never experience any issues with your metal roof. But, there are some things to look out for that can happen outside of your control. You should know what to look for as you care for and maintain your metal roof – and when it is time to bring in a professional and experienced roofing contractor with metal roofs.

When the metal is over-stressed on a roof, you may notice visible waves forming in the flat portions of your metal roof. This can happen when the metal was properly handled, if there is stress from coil slitting, over production, or there simply isn’t enough space for thermal expansion of the metal. It is important to watch for this.


Just like any roofing material, metal isn’t immune to leaks. The point of any roof is to shed water away from your home or building. So, a leaky roof is counter-productive, and is not doing its job of keeping your home or business dry. It is important to have a leaky metal roof evaluated as soon as possible to prevent small leaks from worsening into more costly repairs.

Leaks that start small can be exacerbated over time, causing water damage and mold damage in your home. Sometimes metal roofs can leak because of hail damage, ice damming, structural damage to your roof, gusting winds or driving rain, or accumulation of heavy snow on your roof.

Leaks may not necessarily be from storm damage. It can also occur from improper roof installation, such as if flashing was done incorrectly, seams are open, sealant or fastener issues. A quality Baltimore roofing contractor will ensure that everything is installed properly from the get-go.


When the metal roof is being installed, it is important that your roofing contractor takes care to avoid scuffing the material. Metal has paint applied, so if it is not treated gently, it could be scratched during the installation process causing damage.
