When it comes to roofing materials, there's nothing better than metal. It's extremely durable, resisting impact damage from fallen branches, hailstones, and debris. Insects, moss, and fungi can't wreak havoc on the sheet, making it immune to rot and other forms of decay. It'll stay in great condition for a lengthy period—two to three times longer than asphalt shingles, in fact.
Also, it helps you cut down on energy costs. Metal doesn't absorb sunlight; it reflects it. This keeps the heat out of your home, maintaining a cool indoor temperature. Since you and your family won't be relying on an air conditioner as much, you'll save on your utility bills.
Functionality and sustainability aside, metal adds a wow factor to any home. You can count on this option to enhance a house's look, no matter what architectural style it has. It can even be designed to replicate another material, such as clay tiles, wood shake, and slate.
But all these advantages are accompanied by a downside: rusting. Corrosion occurs when iron-based products interact with oxygen or water, resulting in a reddish-brown stain. As time goes by, this discoloration slowly eats at the material, making the once-strong sheet brittle and flaky.
Luckily, there are ways to prevent this from happening. Here are some solutions that metal roofing contractors use to keep rusting at bay.
Beyond changing a sheet's color, a fresh coat of paint provides resistance against corrosion. Before you climb a ladder with a brush and bucket in hand, there are a few things you should do to prepare the roof for the job.
- First, give it a thorough cleaning, removing all traces of dirt and debris. If you spot a bit of rust, simply scrub it off with a hand wire brush or disc grinder. It's crucial to follow these steps since they'll keep grime from being driven into and trapped on the surface.
- Next, apply a good layer of primer. This creates a smoother and more stable foundation for the color to lock onto. It's also a great way to disguise any stains.
- Finally, once the primer has dried, you can proceed with painting the roof. It's best to use zinc-rich solutions, as the chemical contains amazing corrosion-resistant properties. To keep this barrier looking and working like new, give it a touch-up every 3 years.
Add a Roof Coating
Another way to stop rusting before it begins is by layering on special solutions, such as an elastomeric coating. This acrylic system seals out elements that cause corrosion and rust. As with painting, it's crucial to get rid of all dirt and grime from the surface before applying the sealant, helping it adhere better and last longer.
Elastomeric coatings come in a wide range of colors, so you can also give your roof an aesthetic update upon application. Reapply this every 5 to 10 years.
Apply a Layer of Zinc
For something a little stronger, go with galvanizing. This involves putting a layer or more of liquefied zinc onto the metal to form a protective barrier against corrosion. This substance strengthens the sheet, making it tougher and less reactive to excessive heat, heavy rains, and other natural elements that cause rusting.
The best part about having a galvanized roof is that it doesn't require much maintenance. The only thing you'll have to do from time to time is general cleaning.
