1
Are metal roofs more expensive than a “traditional” roof?
A metal roof costs less than a slate roof, is comparable in price to tile roofing or cedar shake roofing, and costs roughly two to three times what an asphalt shingle roof costs. However, metal roofs are much more durable and longer lasting than asphalt shingle roofs, lasting several generations, saving you money in the long run.
2
Do metal roofs last longer than asphalt or wood shingles?
Yes. A metal roof will last many times longer than a roof of asphalt shingles or wood shingles. Metal roofs can last several generations since metal roofs can often be repainted versus replaced.
The average lifespan of an asphalt roof is only 12 to 20 years and can be even shorter depending on the pitch of your roof and the climate in your area. Asphalt begins to deteriorate as soon as you expose it to normal weather and UV rays, where as a metal roof will never decompose.
Other roofing materials like wood shingle, shake, and tile have varying degrees of weather-related problems that lead to breakdown. Wood shingle and shake roofs often need replacement before twenty years. Concrete tile roofs can crack and warp in the freeze/thaw cycle of more northern climates.
3
Are metal roofs noisier in bad weather?
Normal attic insulation absorbs most of the sound of weather on roofs. As a result, there is little difference between metal and other materials when it comes to noise from rain or hail.
4
Are metal roofs durable in extreme weather?
Metal roofs are incredibly durable. They can withstand decades of abuse from extreme weather like high winds (withstanding wind gusts up to 140 miles per hour), heavy snow (metal roofs shed snow quickly, protecting the structural integrity of the roof), wildfires (protects against ignition if burning embers land on your roof) and more.
5
Are metal roofs too heavy for smaller structures like a detached garage or porch?
Actually, metal roofing is lighter than other roofing options. On average, it is 50% lighter than an asphalt shingle roof and 75% lighter than concrete tile, fiber cement shakes, and slate.
6
Are metal roof environmentally responsible?
Metal roofing is a green building material. A new metal roof contains steel with approximately 28% recycled content. At the end of its lifespan, a metal roof is 100% recyclable. In addition, metals roofs can be installed over asphalt shingles without tearing off and disposing of those shingles. This reduces shingle waste, which is already extraordinarily high. According to the National Association of Homebuilders Research Center, 20 billion pounds of asphalt shingles are dumped into U.S. landfills every year. If you loaded those shingles into tractor trailers, then lined them up end to end, they would make a line from New York City to Los Angeles, back to New York City again, then on to Chicago.
