And Other Common Questions

Metal roof installations for residential properties have become more common in recent years here in Jasper, Georgia and surrounding areas. That leaves us with a few questions, starting with – are metal roofs better? For decades, asphalt shingle roof installations have ruled the industry for residential roofing. They are cost-effective, easy to maintain, and reliable. 

But today, a metal roof installation is almost as common as that of an asphalt shingle roof, and there are several reasons why. So, before you choose your next roof based on the appearance because both asphalt and metal roof installations come in designs and styles that match almost anything you may want, opt for the roofing material that is the best choice for your home. Two popular reasons that metal roof installations are taking off in the industry: 

  • Durability: Just about anything that Mother Nature can dish, a metal roof can withstand it and keep on protecting. While a metal roof installation will typically have a 30 to 50 year warranty, they have been known to last up to 70 years. And though a metal roof has its  weaknesses, like falling tree branches or hailstones denting them, it is still a sturdy roofing material. Asphalt shingle roofing materials are vulnerable to moisture, which can grow algae and fungus. It weakens with UV rays, ice dams form, and the lifespan averages 15 years for most homeowners by comparison.
  • Eco-Friendly: The material for metal roof installation is mostly recycled and when it has reached the end of its lifespan, it can still be recycled. Metal roofs are considered to be a more sustainable roofing material compared to asphalt shingles. A metal roof installation also provides more energy-efficiency because of its reflective qualities, and it blocks heat transmission to a home’s interior. A specialized paint coating can be applied that will reduce the cooling bills even more. This is all compared to asphalt roofing shingles, which require replacement more frequently, adding as much as 20 billion pounds of old asphalt roofing shingles to landfills every year. Additionally, asphalt roofing shingles are made from a petroleum-based product.
