What Is Elastomeric Membrane Roofing and Is It Good for Flat Roofs in Quebec?
Standard bitumen membranes become brittle in cold temperatures and can crack under freeze-thaw cycling. SBS (Styrene-Butadiene-Styrene) polymer modification gives elastomeric membranes their key property: they stretch and recover rather than crack. In Gatineau’s climate, where rooftop temperatures swing from -30°C in January to +60°C on a July rooftop, this elasticity is the difference between a […]
What Are the Pros and Cons of Metal Roofing in Quebec’s Winter Climate?
Metal roofing was the dominant roofing material in rural Quebec for generations, for good reason. Pre-painted galvanized steel performs exceptionally well in the province’s freeze-thaw climate. Key advantages include: permanent lifespan with no replacement needed; natural snow shedding that reduces load and eliminates ice dams; no granule loss or UV degradation; full installation in any […]
Is Metal Roofing Worth the Cost for Homes in Ottawa and Gatineau?
A quality asphalt shingle roof in Gatineau costs roughly $10,000–$14,000 and lasts 25–35 years. Metal roofing costs $18,000–$28,000 and is permanent. Over 60 years, two shingle replacements at increasing costs total $25,000–$35,000+ — while one metal roof installation stays fixed. Factor in no maintenance costs and higher energy efficiency, and the financial case for metal […]
How Much Does Asphalt Shingle Roof Installation Cost in Gatineau, Quebec?
Roofing is priced per square (100 sq ft of roof surface). A standard Gatineau bungalow ranges from 15 to 25 squares of roof area. Key cost variables include roof size, pitch (steeper = more labour), the number of existing layers to remove, the condition of the roof deck, and the number of penetrations (chimneys, skylights, […]
What Roofing Material Handles Heavy Snow and Freeze-Thaw Cycles Best in Gatineau?
Gatineau averages over 230 cm of snowfall annually. Combined with the freeze-thaw cycles that can occur dozens of times per winter, roofing materials are subjected to enormous mechanical and thermal stress. The leading causes of premature roof failure in the Outaouais are ice dam infiltration, freeze-thaw membrane cracking, and snow load exceeding design capacity on […]
What Is the Difference Between Architectural and 3-Tab Shingles for a Quebec Home?
3-tab shingles are a single-layer product with three uniform cutouts along the lower edge, giving them a flat, consistent appearance. They weigh approximately 180–230 lbs per square (100 sq ft) and are rated for wind speeds up to 60 mph in standard form. Lifespans typically range from 15 to 25 years in the Outaouais climate. […]
