Each year, hail causes about 1.6 billion dollars worth of damage to residential roofs in the United States.1 Hail can break, split and cause tear-off damage to traditional roofing materials, resulting in big repair or replacement costs. Metal roofs, on the other hand, are naturally very tough and highly resistant to hail damage. Many insurance companies even offer discounts to homeowners who install an impact-resistant metal roof.
Most metal roofing carries a Class A fire-resistant rating, the highest possible. If you live in an area prone to wildfires, a metal roof is the number one home investment you can make. A common cause of residential fires is due to wind-blown embers, which can travel up to a mile and become lodged in between shingles. Unlike wood shake or petroleum-based asphalt roofs, metal is inherently non-combustible and offers a high degree of fire protection for your entire home.
Roof damage is one of the most expensive cost homeowners face after an extreme windstorm hits their area. High winds are also typically accompanied by heavy rains, which expose homes with compromised roofs to massive amounts of water damage. For areas with inclement weather, metal roofs are the smart choice. Metal roofing can withstand gusts of wind of up to 140 mph. And because they consist of large interlocking panels, metal roofing resist uplift caused by high winds further reducing the risk of water intrusion.
While metal roofing offers exceptional protection from extreme weather including tropical storms, steel roofing has traditionally not been recommended for coastal homes due to the corrosive effects of sea spray and salt air. Modern galvanized steel roofing however is comprised of a steel core with a zinc/aluminum coating surrounding it and delivers great resistance to corrosive marine conditions. Aluminum, copper and zinc roofing will also not rust and provides a lifetime of protection for your coastal home.
A common misconception is that metal roofs are more susceptible to lightning strikes. The probability of a lightning strike is determined by a number of factors including: topography of the area, size and height of structures in the area, relative location to nearby taller structures and frequency of thunderstorms in the area. When struck by lightning, metal roofing actually provides superior protection than traditional roofing material because it is electrically conductive and noncombustible so the threat of fire is drastically reduced.
