Edmonton winters, with their subzero temperatures, harsh winds and freeze/thaw cycles, are extremely hard on roofing materials. Asphalt shingles appear on roofs across the country, but extreme weather causes them to dry and crack, shortening their lives. Fortunately, A. Clark Roofing & Siding LP offers materials designed to withstand long winters. Here are a few of the options.
Concrete roofing tiles are extremely strong and capable of withstanding the most brutal weather conditions. They are even fireproof. The tiles consist of a cured product made of cement, sand and pigments. The weight is equivalent to three layers of asphalt shingles, so check the strength of your roofing system.
Metal roofs have become popular in colder climates and with proper care, a metal roof may last many years longer than a traditional asphalt roof. As the most durable option, metal roofs allow snow and ice to slide right off. However, it’s important to make sure that the roof is large enough that any snow that could build up around your home’s exterior, falls to the ground doesn’t prevent access to the home.
New research published in April 2015 from the University of Calgary’s Schulich School of Engineering, by Joule Bergerson and her research team found significant energy differences between three types of technologies in their life cycle assessment of white roofs, green roofs, and photovoltaic panels.
“We found that roof-mounted photovoltaics are by far the best-performing option in all impact categories,” said Bergerson, assistant professor in the Chemical and Petroleum Engineering Department and the Centre for Environmental Engineering Research and Education. Active, or photovoltaic, solar panels convert sunlight (photons) into electricity. The roofs work more efficiently in northern climates because too much heat degrades the system’s performance.
Other key performance indicators include insulating and sealing the attic floor so the warm air stays in your home and does not rise to the roof. The roof should be about the same temperature as the outside air. A simple roof design that’s tailored to a winter climate is the best way to avoid problems like ice accumulation and buildup of pine needles along the bends in the roof. A simple roof makes it easier to avoid the buildup of snow.
