Asphalt Shingle Roofing
in Calgary

Quality architectural (laminate) fiberglass shingles typically last 25–35 years in Calgary's climate when properly installed. Premium designer or Class 4 impact-rated lines can carry manufacturer warranties up to 50 years. Proper attic ventilation and ice & water shield installation are critical factors in achieving maximum lifespan.

Class 4 is the highest impact resistance rating assigned by UL 2218 testing, where shingles are struck by 2-inch steel balls simulating large hailstones. Calgary sits in Canada's hail belt — southern Alberta experiences more hail events per year than almost anywhere else in North America. Class 4 shingles can also qualify you for insurance premium discounts with several Alberta insurers, often offsetting the upgrade cost within a few years.

Yes — and beyond the code minimum. Alberta Building Code requires ice and water barrier along eaves and in valleys, but Calgary's intense freeze-thaw cycles create significant ice dam risk. We install ice and water shield at least 24 inches past the interior wall line on all eaves, covering the first two to three courses of shingle. This protects your roof deck during the worst winter conditions.

Pricing depends on home size, roof pitch, number of layers to remove, and shingle grade chosen. A typical Calgary bungalow (1,200 sq ft home, approximately 1,500 sq ft roof) ranges from $8,000–$16,000 installed for architectural shingles. Two-storey homes generally range from $12,000–$24,000.
