The New Trend in Residential Metal Roofing

You’ve seen steel roofs on barns, but how often have you seen them on residential property? It’s very likely you’ll be seeing them a whole lot more around the country. With wildfires, hurricanes, hail and other extreme conditions damaging houses, an increasing number of homeowners roofing companies toronto are taking advantage of the benefits of metal roofing.

Steel roof installations have more than doubled in the last five years and will continue to grow 15 percent per year, according to the Metal Roofing Alliance (MRA). There is no material more capable of protecting a home from destructive weather conditions.

Benefits of Metal Roofing

§ Durability

A metal roof will last at least two to three times longer than an asphalt roof, or 40 to 60 years. In the warm, humid Southern states, metal is virtually immune to the unsightly mildew stains that often form on asphalt shingles. Properly installed, a metal roof won’t leak or rust and can withstand wind gusts up to 140 miles per hour.

Shane Scott, a real-estate entrepreneur from LaGrange, Georgia, renovates and resells older homes. He installed a metal roof for his own home in 2000 and was so pleased with it he’s purchased metal roofs for all the homes he’s refurbished since then.

“When buyers are considering a home, they’re always concerned about the condition of the roof,” notes Scott. “With metal, they know they won’t need to do anything to it for at least 50 years. With an asphalt roof, they’ll need to replace it within 15 to 20 years.”

§Protection

Most metal roof systems have passed UL 2218 Impact Resistance testing at its most severe level, Class IV. As a result, homeowners in hail-prone states who choose metal roofing may be eligible for discounts on their insurance premiums.

Ed Parker, a retired homeowner from Sharpsburg, Georgia agrees. “We’ve gone through two or three asphalt roofs on our home over the years and they discolor and rip off during wind storms, or leak due to hail storms,” Parker said. “Metal is much more durable.”

§Environmentally Friendly

The National Association of Homebuilders Research Center estimates that 20 billion pounds of asphalt roofing is taken to landfills every year. Metal’s longevity removes the need for frequent roof replacements. Better still, it can be laid over the current roof, eliminating the costs of shingle removal and land-fill fees. If a metal roof is ever removed, it can be recycled.
Steel is the best choice for “green” buildings, where the goal is to reduce or eliminate chemical substances, according to the American Iron and Steel Institute (AISI). Unlike wooden shakes or some other traditional materials, steel is not vulnerable to insects, mold or rot. Therefore, it does not require the application of insecticides or other hazardous chemicals.

§Energy Efficient

Time-tested metal roofs save energy and reduce your cooling costs by as much as 40 percent, depending on location, says the MRA. The advent of new reflective paints with energy-saving properties has revolutionized the residential roofing industry.

While asphalt and cedar shingles absorb heat, the new cool pigment technology can reflect up to 85 percent of the sun’s radiant energy. Now, even dark colors achieve the “cool” attributes. An Energy Star roof can stay up to 100 degrees cooler on its surface than other roofs, so less heat is transferred into the building.

Wilmer Dykes, a homeowner from Cochran, Georgia, noticed a decrease in his energy bill of at least 25 percent after installing his metal roof. Dykes believes keeping his old roof on his home helped save energy. “By building the new metal roof over it, we created an air pocket between the two roofs, giving us an added layer of insulation,” he said.

§Low Maintenance

A metal roof won’t crack, curl, split, rot or lose impact resistance with age. The only maintenance recommended for a metal roof is an annual inspection, clearing the roof of accumulated leaves or other debris and checking roof top ancillaries and air conditioners to ensure that they are properly drained and supported.
