Metal roofs have come a long way since the days of rusty, corrugated tin roofs found on barns and storage buildings. Still, people who are interested in metal roofs that are nearly indistinguishable from roofs made of asphalt shingles might be worried about rust and corrosion. Though they might not occur for a long time, rust and corrosion do happen on even a contemporary metal roof. Here are ways to minimize these issues.
Find a Reputable Roofer
The first thing to do if you’re worried about rust and corrosion is to find a professional who knows how to install metal roofs. The one sure thing that causes corrosion is when two different metals come into contact with each other. Corrosion has nothing to do with maintenance or the quality of the materials; it’s a chemical reaction. Because of this, all the fastenings and findings must be the same type of metal as your roof shingles. A professional also knows how to properly seal your metal roof.
Keep Your Roof Clean
One sure way to prevent corrosion or rust is to keep your metal roof clean. Clean off any leaves, twigs, or dirt. Clear the valleys of anything that traps water, such as algae. Standing water can destroy your roof’s protective coating. You should also make sure that your gutters and drain spouts are kept clear.
Depending on the size of your home, you may be able to clan your roof with a long-handled broom, a garden hose, or even a pressure washer. If the only way to thoroughly clean your roof is to climb up on it, you can call a professional roofer if you’re too anxious to do this yourself.
Add Protective Coating
Your roof probably came with a factory-installed protective coating, especially if your roof is new. This coating can last for decades, but factors such as your climate and how well your roof is maintained can shorten its lifespan. The material of the coating also affects its lifespan. PVDF, or polyvinylidene fluoride, for example, can last over 40 years. Still, there might come a time when the coating needs to be refreshed to prevent rust and corrosion. Some types of metal roof coating require skill to apply, so this job is better left to a professional.
Make Sure Fasteners Are Sound
Make sure the screws and the fasteners on your metal roof are sound, not too tight, and have neoprene washers of excellent quality. Neoprene washers can make screws and fasteners waterproof, and they bear up under bad weather and the sun’s ultraviolet light. Screws should also be treated with an edge sealant that also protects them from moisture.
A well-cared-for metal roof can last decades, and there are simple ways to keep the rust away. If you have concerns or require metal roofing services, contact River Roofing in Springfield, OR.
