We hope that all of our neighbors in the greater Portsmouth and southern Maine area survived Hurricane Sandy and that you did not suffer any personal injury or damage to your house or business. As one of the leading metal roof fabricators and installers in the region, we are often asked how metal roofs stand up to storm conditions, so we thought that we would address that topic in this article.
In general, metal roofs hold up as well, if not better, than other forms of available roofing systems regardless of the type of storm. For storms like Hurricane Sandy with high winds, metal roofing can provide significant wind resistance since the roof is a structural element and thus can perform better than other traditional roofing materials. In addition to that, metal roofs are predictable in their performance behavior and it does not degrade over time, whereas other roof systems will not perform consistently throughout their typically shorter useful lifetime. With regard to lightning, metal roofs are no more likely to attract a strike than a traditional material, but if it should happen, metal roofs dissipate the energy from the strike and actually makes the roof and house less susceptible to catching on fire. Finally, we are often asked about the sound of a metal roof and whether this is an issue during a severe rain or hail storm. Employing the proper installation techniques that Performance Roofing professionals are trained to do, metal roofs are actually no louder than traditional roofs that use asphalt or other materials. The proper use of plywood decking and batt in the attic to insulate the house ensures that your metal roof will not leak nor cause undue noise to distract those inside.
