Metal Roofing Questions and Answers
Metals' advantages over asphalt shingles
- Longer warranties - metal roofing often carries manufacturer's waranties of up to 50 years. That compares favorable to asphalt shingles, which may need to be replaced every 15 to 20 years. If you compare the average annual metal roof prices to shingles, metal is competitive over the long haul because you need to repair and replace it less often.
- Lower energy bills - metal reflects heat from the sun helping your roof and home stay cooler, using less energy.
- Non-combustible and fire resistant - residential metal roofing has a Class A fire rating, which means it receives the designation of "most resistant" to fires.
- Lightweight roof material - metal doesn't put as much stress on the roofing structure, since it weighs far less than asphalt shingles.
- Durability - metal roofs can withstand winds of up to 140 mph and large hail without getting damaged.
Potential disadvantages of metal roofing
Metal roofs carry a steeper upfront cost compared to asphalt shingle roofs, which turns many people off. However, a metal roof is a far more cost-effective option when you take a look at its long term cost savings. You may replace two or three asphalt shingle roofs during the lifespan of one metal roof.
It’s important to factor in the length of the warranty and expected lifespan of a roofing system to accurately determine its true cost of ownership (TCO). One easy way to do this is to divide the total upfront cost of the roofing system by its warranty in years. The bigger the number, the better the TCO.
