Metal roofs provide many advantages, from being resistant to pests, mold and heat, to providing you with a long-lasting roof option. However, like all roofing materials, metal needs regular maintenance in order to keep providing you with these benefits. Here are some helpful tips for maintaining your metal roof.
Look for Signs of Rust and Corrosion
While metal roofs can withstand a lot of different incidents, excess water on the roof can lead to rust and corrosion. It is important to inspect your roof on a regular basis to look for signs of rust or corrosion and make repairs as needed. Rust typically happens when it rains or snows and that water pools on panels or in the gutters. It is a good idea to clear the gutters regularly as well to prevent this from happening. You can also seal your roof to reduce the risk of corrosion.
Repair Any Open Seams
After checking for rust and corrosion, you should also inspect the roof for open seams. Seams are used when using metal panels for a roof, as opposed to metal shingles. If you have seams that are open, it could leave the materials underneath the metal panels susceptible to damage from heat, water, and mold. It is important that you repair these seams as soon as possible. You might want to hire a professional contractor to handle this as they will also check the materials underneath to be sure no damage has been done.
Don't Let Metal Materials Touch Each Other
Another thing to check is that different forms of metal materials on your roof are not touching each other. It is okay for panels or shingles to touch each other, but different types of metals, such as metal, copper, or steel, could cause a chemical reaction when they come into contact with each other. This is why you should choose just one type of metal for all materials, including the panels, shingles, flashing, and downspouts.
Get the Roof Re-Sealed
Lastly, get your metal roof re-sealed about once a year or so. It should be sealed when it is installed, and then routinely after that. Sealing the materials on your roof helps to avoid corrosion, rust, and damage from external sources. There are different types of sealants that work on metal materials, though sealants that contain polymer tend to work the best. Polymer protects your roof from heavy winds, rain, ice, dirt, and dust.
