Advantages and Disadvantages of a Metal Roof
The initial cost for a premium metal roof can be higher than shingles or other roofing materials. But in the long run, you could save money. Asphalt roofs often require re-roofing every 10 to 20 years, but a high-quality metal roof can last 40-70 years. However, investing in a metal roof may only make sense, if you plan to stay in your home long enough to enjoy the cost benefits. Fortunately, a metal roof can also increase the resale value of your home.
Metal roofs can sustain wind gusts up to 140 miles per hour, depending on the material. They will not corrode or crack. Some metals are also very impact resistant. Steel metal roofing has a “metallic coating” made of either zinc or a combination of zinc and aluminum. This prevents rust from forming and is bonded to the steel at the factory. Paint is then applied over the coating to give the long-lasting color property owners require. A Metal roof doesn’t need the regular maintenance that other roofing materials often require.
