Commercial Roofing Services in Calgary

For more than two decades, CMP Roofing has been the commercial roofing contractor Calgary property managers, building owners, and facility teams call when a flat roof has to perform. We've completed 550+ commercial roofing projects across the city — from single-storey retail plazas and 15,000 sq ft warehouses to multi-tenant office buildings and industrial facilities. Every crew is COR-compliant, fully insured, and backed by $10M in liability coverage and manufacturer-certified installation training.

Why Calgary Commercial Roofing Demands Local Expertise

Calgary is one of the most demanding roofing environments in Canada. Chinook-driven freeze-thaw cycles, summer hailstorms, heavy spring snow loads, and intense UV at altitude all attack low-slope membranes differently than they would anywhere else. A commercial roof installed to a generic spec doesn't last here, which is why experienced Calgary roofing contractors design for this climate from the start. We design, install, and maintain flat roof systems specifically for Alberta's conditions — correct slope to drainage, reinforced flashing details at every penetration, and membranes matched to your building's thermal and traffic profile.

Why Calgary Businesses Choose CMP Roofing

We work exclusively on commercial and industrial low-slope roofs, so your project is handled by crews who do this every day — not residential installers stretching into flat work. You get a single accountable contractor for the full lifecycle: assessment, system recommendation, installation or replacement, warranty registration, and ongoing maintenance. Workmanship is warrantied for a minimum of five years and manufacturer membrane warranties run 15–30 years depending on the system and tier. When a leak can't wait, our 24/7 emergency line gets a crew on site to stop water intrusion before it reaches your inventory or operations. Comparing roofing companies in Calgary? Ask every bidder for proof of insurance, ARCA membership, and local commercial references — we provide all three up front, and our Calgary commercial roofers are employees, not brokered subcontract crews.

What Does Commercial Roofing Cost in Calgary?

Commercial roofing is priced by system, roof size, deck condition, access, and the number of penetrations and details. As a planning benchmark, a 5,000 sq ft flat roof replacement in Calgary typically ranges from roughly $40,000–$70,000, with TPO and SBS-modified bitumen falling mid-range and PVC at the premium end for grease- or chemical-exposed buildings. Targeted repairs and maintenance programs cost a fraction of replacement and can extend a sound roof's life by 10+ years. The only way to get an accurate number is an on-roof assessment — which we provide free, with a written scope and itemized quote.
