Metal roofs are far more durable than traditional shingle roofs, and some require very little maintenance. While metal roofs aren’t indestructible, they’re the next best thing and typically take a long time to show wear and tear. However, metal roofs will start to show their age after a few years or in response to the climate. Here’s an overview of what to expect from your Pittsburgh metal roof.
Battling the Elements
Some types of metal roofing materials are better in some climates than others. Areas with a lot of wet weather do better with a Galvalume roof, while homes near the coast need aluminum to prevent corrosion. By understanding the elements your Pennsylvania roof will need to face, you can pick the right metal roofing materials for your region.
Chalking and Fading
Chalking is a white powder that forms on the surface of painted metal over time. The breakdown of the resins coating the surface of the metal panel cause a layer of white chalk to form. You may not notice it at first, but a swipe of your hand over the surface will come up with white powder. The degree of chalking depends on the type of paint used to coat the panel and the elements of the local area. Reduce the effects of chalking on your roof by identifying the proper coating for your area and by using the correct type of metal roofing.
Fading happens over time on any painted surface, not just metal roofing. The wind, rain and other elements take their toll on the surface of the metal, causing discoloration and sometimes a complete change of the original color. Nothing can stop this process, but fortunately, it does not affect the function of your metal roof.
Inspect your roof regularly for signs of wear and tear. Being proactive can catch small problems before they turn into a major repair bill. Watch for peeling, cracking, flaking, and corrosion on the surface of your metal roof. These signs can indicate your paint is failing and your roof needs a new coat. If you suspect this is happening before the warranty is up, contact the manufacturer of the panels to find out the details. Most sealants last about 20 years.
Don’t allow standing water to puddle on the roof’s surface. This can cause corrosion and rust to form, damaging the surface of the panels. Seal small holes and cracks with roofing cement, and the seams may need resealing when facing harsh elements.
These tips and tricks will keep your roof in great condition. Metal roofs typically require less maintenance than more traditional roofing materials. Check with your roofer to see if a metal roof is the right option for your home.
