Metal roofs are often lighter than asphalt shingles. You will be surprised to learn that a metal roof is, on average, 50% lighter than an asphalt shingles roof, and 75% lighter than any other roofing materials. To give an idea; asphalt shingles usually weight from 275-425 pounds per square feet, depending on brand and style. By comparison the average metal roof will weight around 100 lbs per 100 sq feet.The lightweight nature of steel roofing and other types of material means you do not have need as many roof supports and you do not have to worry about your roof sagging under the weight of the roofing material.
With a metal roof snow slides off easily before it can accumulate and rain never gets a chance to pool and seep in yo create water damage. No more worrying about all that is been accumulating on the roof.
