Prized by homeowners for the ability to last for decades without needing replacement, metal roofing is one of the most highly sought after types of roofing for residential properties. If you have a metal roof, you will rarely run into issues in the first several decades, but there can be some problems that will call for roof repair. Here is a look at some of the common issues, how they happen, and how they are repaired.
Gaps show up at the seams between the metal panels.
When a metal roof is installed, the panels are butted together in an almost overlapping fashion. Over the years, the panels can shift and move and leave gaps between the panels. These gaps can be problematic because they make a way for water to get into the underlying materials and cause roof leaks into the house. Thankfully, this kind of issue is relatively easy to repair; typically, the only thing required is some readjustment and refastening of the panels, which is quick to do.
Fasteners holding panels in place sink through and leave a hole.
It is rare with new metal panels, but common with older panels for the fasteners to punch through a roofing panel and create a hole. The reason this happens is this spot is where most of the stress is on the panel over time. The pressure of the fastener against the panel, especially in areas that sustain a lot of wind, can cause a puncture through the metal as it grows weaker. The fasteners can be repositioned, but the metal will still have a small hole where the old fastener was situated. Smaller holes can be patched, but if the hole is rather large, the full panel may have to be replaced.
Metal panels buckle and become misshapen due to wind.
Perhaps one of the most common problems with metal roofing that will require a homeowner to reach out for repair is bent panels. Even though metal roofing panels tend to be rather resilient, they can bend and become misshapen if they break loose during periods of high wind. You may have a single panel that seems to curl up from the rest of the roof after a storm or a few panels that have bent almost double. These panels may not be repairable by simply tacking them down; the panels do often have to be replaced to restore the uniform appearance of the full roof.
