Metal Roofs Are Becoming More Common
At one time, metal roofing could only be found on high-end, architect-crafted homes. That is no longer the truth. Metal roofing is now commonly used on conventional houses, thanks to increasing availability and improved manufacturing processes. According to industry statistics published in 2017, the market share for metal roofing increased at a rate of roughly three percent each year for a few years and about 15 percent of all roofing installations use metal roofing materials.
Roofs Aren’t Loud Like Most Think
Although it’s a common misconception that metal roofs are noisy when rain or hail falls on them, the reality is that when properly installed, metal roofing is no noisier than any other type. Metal roofing is typically installed over a solid substrate. Additionally, the attic and insulation provide a sound barrier. From interior living spaces, inhabitants rarely notice any increase in sound levels when a metal roof is installed.
Lightning Isn’t a Problem
Although you may think that a metal roof will attract lightning, this is not supported by facts or statistics. According to a technical bulletin from the Metal Roofing Association, “Metal roofing does not in any way increase the risk of a lightning strike.” “Furthermore, if metal roofing does happen to get struck by lightning, it is less combustible than conventional roofing materials such as wood shakes or shingles.”
They Last Longer
Although the vast majority of metal roofing products come with warranties comparable to the very best asphalt shingles (about 30 years), in practice, metal roofs have been known to last 50 years or more. According to State Farm Insurance Statistics, metal roofs routinely have a life expectancy of 40 to 70 years.3 As a result, it is very rare for a homeowner to install more than one metal roof over the time he or she lives in the home.
They Are More Energy Efficient
Industry-backed studies demonstrate that metal roofs reflect solar radiant heat, which can reduce cooling costs by 10 to 25 percent.3 In climates where cooling costs are higher than heating costs, coating a metal roof with a shiny or granular coating can optimize the reflective capacity of the roof and improve energy savings.
