Many homeowners make the switch to metal roofing because, with proper care, it can last several decades longer than materials like asphalt shingles. However, increased longevity doesn’t necessarily mean that metal roofing is problem-free. Harsh weather elements, especially hail and high winds, can take a toll on the metal. This is why it’s important to familiarize yourself with common metal roofing problems. If you can recognize the early warning signs of damage, it’s easier to take action before the problems become more severe and expensive to repair.
Rust and Corrosion
A lot of people worry about corrosion on metal roofs. The truth is, though, metal roofs often have a protective coating added to them that specifically reduces the risk of rust. Still, over time, that coating can deteriorate, especially when it gets scratched from falling branches and windblown objects. And once it does, those areas become vulnerable to moisture, which may eventually lead to rust and corrosion. Ideally, you’ll call a roofer as soon as you see scratches or signs of rust so they can inspect and repair the damaged areas, which may entail adding another layer of protective coating.
Separated Seams
The metal panels on a metal roof are connected to one another with seams. Those seams need to stay tight and properly sealed at all times to prevent water from leaking underneath. If you live in an area with extreme temperature swings, the repeated expansion and contraction can cause the seams to become loose or even to completely separate. Once water leaks underneath, it may damage the insulation, decking, and other materials.
Missing Fasteners
Just like the seams holding the panels together, the fasteners can also become loose over time. Strong winds are a common reason for this problem. Just one missing fastener can put the entire roof at risk of water intrusion and further damage.
Condensation Under the Roof
Even if the seams and fasteners are tight and in good shape, metal roofs can still experience condensation problems when warm, humid air rises and encounters the cooler underside of the metal panels. If the roof doesn’t have proper ventilation and insulation, that moisture will continue to accumulate and contribute to mold growth, damp insulation, corrosion, and damage to the roof deck.
The Importance of Professional Installation and Maintenance
For a lot of homes, metal roofing problems trace back to improper installation or the neglect of maintenance. This is why it’s so important to have the roof mounted by a licensed roofer who has many years of experience installing metal roofs in your region. You’ll be able to rest assured the expert will use methods that specifically address common local weather conditions.
As far as maintenance, most metal roofs need at least one inspection a year. However, if you live in an area with frequent hail or high winds, you’ll also want to schedule maintenance after each severe storm so that the roofer can check for loose fasteners, separated seams, and deteriorated sealant.
One of the easiest ways to keep your metal roof in good condition is to do an inspection from the ground once a month. To do this, you’ll walk around your home, looking at the roof for rust, loose panels, and visible damage. If you notice any signs of trouble, it’s best to schedule a professional inspection as soon as possible.
