Canadian homeowners are increasingly recognizing the advantages of cool metal roofing as an innovative way to enhance the energy efficiency of their home. Contrary to common misconceptions, a cool roofing system doesn’t have to be flat or white to be effective. In fact, Classic Aluminum Roofing Systems come in a wide variety of profiles and colours that have high energy efficiency ratings.
Cool Metal Roofing provides increased value to your home that will not diminish over time. Enhanced beauty, home value, and protection are some of the reasons why more Canadians are choosing to upgrade to a Classic Aluminum Metal Roof. From a practical point of view, energy efficiency is a major deciding factor.
Why are Classic Aluminum Roofing Systems So Energy Efficient?
Reflectivity: Our Kynar 500® and Hylar 5000® coatings incorporate our advanced hI-R Heat Barrier technology to create a roof that keeps your home naturally cooler, thanks to special reflective pigments. The complex chemical structure of these pigments reflects the infrared portion of the sun’s rays that is most responsible for heat gain. A hI-R Classic roof leaves the attic space and the entire home much cooler in the summer. Proud owners of Classic Aluminum Roofs report saving up to 20% or more on their energy costs.
Emissivity: Compared to most other roofing materials available today, aluminum roofing has a high emissivity. High emissivity means it does not retain absorbed heat for a long period of time.
Energy Efficient Roofing Reduces Cooling Bills
The blocking of both radiant and conductive heat combined with high emissivity aluminum provides the best possible recipe for a cool roof for your home. Studies have shown reduced attic temperatures of up to 34%. When your attic is kept cooler, your air conditioner runs less and you save money.
“Under our old roof, with the temperatures that we have been experiencing, the in-house temperature would rise all day, in spite of our central air unit running constantly. With our new roof, the in-house environment stays at a comfortable 72 degrees, and the central air unit operates only as needed. There is almost no difference in the temperature between the ground floor and the second storey, where before, the upstairs might be five to ten degrees warmer. We are really pleased!” – Henry Smith, Ancaster ON
Thermal Mass: The ability of a low weight Classic Aluminum Roof to be installed over your old shingles is also beneficial. In addition to saving your money and avoiding landfill disposal, your old roof provides thermal mass. Thermal mass is additional insulation to help keep summertime heat outside of your attic.
Ventilation: A Classic Metal Roof can also help you achieve good attic ventilation. Ventilation is a key to even greater energy efficiency, and it also helps guards against winter ice damming in cold climates.
