Choosing the best material for your new roof involves several factors, but the most important factor in comparing roofing materials is the life expectancy. Asphalt roofs generally last 15 to 20 years. The weather is a prime factor in shingle life span. In the colder northern states, sloped roofs can last 25 years. In the southern hotter climates, such as in Florida, asphalt shingles often deteriorate in 12 to 14 years. Metal roofing panels will last between 40 and 60 years, close to two times longer than asphalt roofs in the North, and up to five times longer for the South.
Metal roofing is becoming more popular, even though prices are often three times higher than the cost of conventional asphalt roofs. Some consumers find them the preferred alternative. Metal roofs are constructed from metal tiles or pieces and are preferred by some consumers due to their lightweight and durable nature. Because of this, most companies provide a warranty of 40-years, vs that of shingle guarantees of 20 to 25 years.
The question I keep hearing, when the topic of metal roof vs asphalt comes into to the discussion, is – how noisy is a metal roof? Properly installed metal roofing today is actually no noisier than any other type of roof. Metal roofing is typically installed over a solid substrate. Additionally, the attic and insulation provide a sound barrier. Also, because of the weight difference, a metal roof may often be installed on top of an existing shingle roof, avoiding the mess and cost of removing the old shingles. The new metal roof might be elevated over the existing roof by means of furring strips. These furring trips will create an air pocket, which will further deaden sound.
A metal roof can withstand decades of abuse and extreme weather like high winds, heavy snow and hailstorms. A metal roof can withstand wind gusts up to 140 miles per hour. Not only is metal roofing great for your home, it’s great for the environment, since they can be fully recycled. The new Metal roofs come in every type of designer’s choice and style and when correctly installed, can mimic the look of asphalt and most manufacturers guarantee the color for 20 years. A home with metal roof can blend in any neighborhood.
