Roofing is one of the more punishing trades to operate in Calgary. Hail seasons, chinook wind cycles, and freeze-thaw patterns specific to the eastern Rockies foothills mean Calgary roofs face stress that roofs in milder Canadian markets simply do not. Yet most Calgary homeowners and commercial property owners walk into roof replacement decisions with little market data on what shingles actually perform here, what flat roofing systems Calgary commercial installers prefer, and what realistic pricing looks like in 2026.
One of the more useful first-hand datasets on this comes from EZ Roof Repair, a Calgary roofing company founded by Sokol Preka that has documented its installation patterns across nearly 1,850 residential roofs and over 428 commercial properties in the Calgary area. The company's findings, published on ezroofrepaircalgary.ca, give Calgary property owners a concrete reference for what's actually being installed, by which brands, and at what cost.
According to EZ Roof Repair's records, asphalt shingles account for over 85% of residential roofing installations across 1,848 completed Calgary residential projects, and roughly 8% of commercial installations. The brand distribution the company documents is concentrated: IKO, Owens Corning, and Malarkey substantially outsell BP, GAF, and CertainTeed in Calgary. EZ Roof Repair's preferred residential shingle is the IKO Dynasty, citing its class 3 hail resistance rating and 130-mph wind warranty as the best value-for-money combination available.
EZ Roof Repair also tracks the physical profile of the average Calgary residential roof. The typical Calgary residential roof in their dataset is around 2,000 square feet, with a 2/12 pitch (18.4 degrees) and a roof height of 12 feet. Most of the company's residential clients indicate they plan to stay in their current home for at least 5 more years, which the company notes is a significant factor in choosing between budget and premium shingle products.
On the commercial side, EZ Roof Repair's data shows a different picture. Across 428+ commercial properties the company has roofed, SBS flat rubber roofing was chosen on over 45% of buildings, with EPDM coming second at 38%. PVC and TPO thermo-plastic membranes remain a minority of installs because of higher material costs, though EZ Roof Repair reports year-over-year growth in both. PVC stands out as the only commercial flat roofing product that can be substantially recycled at end-of-life.
The brand picture on the commercial side is similarly concentrated. EZ Roof Repair documents IKO and Soprema as the dominant SBS manufacturers in the Calgary market, with Carlisle and Elevate leading on EPDM. Average commercial dimensions in the company's dataset come in at roughly 5,000 square feet, a 1/12 slope (4.76 degrees), and a 20-foot two-story height. Over 95% of EZ Roof Repair's commercial clients now consider added slope packages important for water shedding, with EPS and polyisocyanurate slope systems increasingly specified on new installs.
EZ Roof Repair's residential repair data reveals a pattern most Calgary homeowners would not predict. Out of 1,560 residential roofs the company has repaired, over 80% involved water-pooling areas: chimney leaks, skylight leaks, and vent or flashing leaks. The remaining repairs were distributed roughly evenly between damaged shingles, missing sealant, and acts of God like hail or wind damage. EZ Roof Repair attributes the dominant cause to faulty workmanship, with material failure ranking second.
On commercial properties, EZ Roof Repair documents a similar pattern centred on transition points: areas where the roofing membrane bends up a wall or wraps around a penetration, plus zones around drains and scuppers where water collection compromises seams over time. The company recommends preventative maintenance every 5 to 10 years on commercial roofs, with formal inspections every 2 years once a roof reaches 15 years of age.
EZ Roof Repair's pricing data gives Calgary property owners a usable benchmark. Residential roof replacements in Calgary range from $8,000 to $46,000, with the average coming in around $12,800. Residential roof repairs range from $450 to $7,500 with an average of approximately $2,800. On the commercial side, EZ Roof Repair documents repair costs ranging from $1,650 to $18,000, averaging around $9,500 per commercial repair project.
EZ Roof Repair's data shows growing but still niche demand for eco-friendly roofing in Calgary. On the residential side, the company highlights Euroshield, a Calgary-based manufacturer producing rubber shingles made from 95% recycled compounds (up from 75% just a few years ago), primarily sourced from used tires. Steel panel roofing also incorporates 25 to 35% recycled content on average. EZ Roof Repair notes that Euroshield products currently account for only 1 to 2% of their projects, but the company expects year-over-year growth.
EZ Roof Repair also flags a sobering statistic on shingle recycling: in the Calgary area, only about 15% of discarded asphalt shingles are actually recycled, despite landfill discounts on construction material. The company attributes the gap to the cost of building recycling facilities and the fact that virgin fiberglass and bitumen inputs remain cheaper than extracting them from old shingles. Until that economic gap narrows, EZ Roof Repair does not expect significant changes in shingle recycling rates.
EZ Roof Repair's installation data converts what is usually an opaque buying decision into something measurable. For Calgary homeowners, the default choice is asphalt shingles from IKO, Owens Corning, or Malarkey, with realistic replacement budgets centring around $12,800 for a typical 2,000-square-foot home. For Calgary commercial property owners, SBS and EPDM dominate flat roofing, slope packages should be specified on new installs, and brand selection should be driven by warranty terms and material recyclability for long-hold properties.
The broader takeaway from EZ Roof Repair's first-hand data is that Calgary roofing failures are largely workmanship problems concentrated at transition points (chimneys, skylights, vents, flashings, drains), not material failures. Calgary property owners evaluating roofing quotes should weigh installer experience with these specific transition details as heavily as the shingle or membrane brand itself.
