Madison Roofing: Article About Metal Roofing: The Pros and Cons
When discussing roofing materials with a Madison roofing company, Wisconsin homeowners may want to consider metal roofing. Steel, copper and aluminum roofing is especially suited to areas subjected to heavy rain or snow. Because metal roofing conducts and reflects the sun's heat, snow slides off quickly, reducing the chances that melted snow will refreeze over the eaves of the roof and form an ice dam. Because metal roofs reflect rather than absorb the sun's heat, they also help cool homes in the summer.
Metal roofing has other advantages over more common asphalt shingles. While asphalt shingles can be subject to rot, mildew and moss buildup, metal roofing is immune to these threats. Further, a metal roof offers no food source for insects such as termites or carpenter ants. Because metal roofs are installed in large sheets that are tightly sealed together, rather than nailed down rows of small shingles, there is less opportunity for leaks to occur.
Furring strips are used to install metal roofs over the existing roof. This installation is one of the reasons that metal roofs are no noisier than roofs covered with asphalt shingles. The raised space created by the furring strips creates a sound deadening air pocket. As with asphalt shingles, the attic and insulation provide additional sound barriers.

Homeowners may have to make an additional investment, however, for the installation of this type of insulation.
During a storm, metal roofs resist high winds extremely well, and they do not attract lightning any more frequently than a standard asphalt shingle roof. However, in contrast to asphalt or shake shingles, a metal roof is much less likely to catch fire after it has been struck by lightning. In areas where wildfires may occur during a drought, a metal roof protects the home by extinguishing the embers that fall on it.
Metal roofs do have their downsides, nonetheless. They are far more expensive than asphalt shingles, and that cost is not necessarily offset by the greater life expectancy of a metal roof. While a metal roof may last for up to 50 years, the underlying substrate may need replacing after 30 years. Metal roofs are less expensive than other roofing materials, however. A metal roof complicates the installation of skylights, tube lights and other modifications. Further, metal roofs are slippery and become more so when wet. While all metal roofs can withstand pea size hail, larger hailstones can damage copper and aluminum roofs. Only a professional roofer should inspect them for damage, in addition.
