AIA Blog - Metal Roofs Can Be A Fire Hazard For Your HomePosted on 01.15.13 by
Metal roofs have become popular in rural areas because they last longer and are lighter than conventional roofing materials, but they may be a hazard if your house ever catches fire, according to WIVB.com reporter Al Vaughters.
For example, firefighters in New York recently had some tense moments when they were on a roof they didn’t immediately realize was made of tin. Fire chief Steve Pacanowski explained that the home had a metal roof installed over layers of asphalt shingles, which held heat in, compounding problems for the firefighters.
Metal roofs create numerous problems for firefighters. They require special cutting tools to get through, and they can hide the location of the fire inside and its true intensity. “Walking on a metal roof could be the equivalent of walking on a built-up roof with ice on it. Because it is metal it tends to be a little slipperier. Our whole purpose for being up on the roof is to gain access, and release those super-heated gases, and that heat and flames, if that is what’s underneath, and get those out.”
Also, because the roofs are lighter, the supporting materials may also be lighter, which can cause the roof to fall down faster than most standard roofs. They may seem convenient for your home because of how long they can last, but metal roofs are terrible in less-than-ideal conditions. I would strongly reconsider if I was planning on getting one any time soon.
