WHERE THE FIRST THING WE BUILD IS TRUST
CPR Group Ltd installs, maintains, and repairs commercial roofs across Calgary, including TPO, EPDM, SBS modified bitumen, and standing seam metal systems. Since 2007, CPR Group has worked on office buildings, warehouses, multi-unit residential properties, and retail sites across Southern Alberta.
Every commercial roofing project is backed by $5 million in commercial general liability coverage, SECOR safety certification, and a written scope of work before any crew steps on the roof.
Since 2007, CPR Group Ltd has served Calgary and Southern Alberta with full-service roofing, property restoration, and exterior renovations.
We offer a comprehensive range of commercial roofing services to meet the diverse needs of Calgary businesses:
CPR Group heat-welds TPO (thermoplastic polyolefin) single-ply membranes for continuous, watertight commercial roof surfaces. TPO's reflective white surface reduces cooling loads on Calgary office buildings and warehouses, and resists chemical exposure from HVAC exhaust.
Our crew torch-applies or cold-adheres SBS modified bitumen membranes for commercial roofs that need superior puncture resistance and flexibility. SBS systems handle Calgary's freeze-thaw cycles and work well on roofs with foot traffic or rooftop mechanical equipment.
CPR Group installs and repairs EPDM (ethylene propylene diene monomer) single-ply rubber membranes, a flexible system that holds up to Calgary's temperature swings without cracking or seam failures.
Our team installs standing seam metal roof systems for commercial buildings that need long service life, high wind resistance, and hail performance. Standing seam is one of the most durable commercial roofing options available in Alberta.
CPR Group repairs leaks, failed seams, damaged flashings, and ponding issues on all commercial membrane systems, with documentation suitable for insurance claims or warranty files.
Our crew inspects membranes, drains, flashings, and rooftop penetrations on a scheduled basis, catching small failures before they become full replacements.
Since 2007
CPR Group Ltd, trusted Calgary roofers since 2007, has installed and repaired commercial roofs across the city on office buildings, warehouses, strip malls, multi-family properties, and strata-managed complexes. CPR Group is a member of the Alberta Allied Roofing Association (AARA) since 2021 and the Canadian Condominium Institute, South Alberta, giving property managers and building owners a contractor who understands both the technical and contractual side of commercial work. Our HAAG Certified Inspectors produce the inspection reports and damage documentation insurance adjusters require for commercial claims.
Every CPR Group commercial roofing project is backed by $5 million in commercial general liability coverage through Federated Insurance, SECOR safety certification (Partnerships in Injury Reduction through the Alberta Construction Safety Association), active WCB-Alberta coverage since February 2013, and a BBB A+ accreditation held continuously since July 2015. CPR Group serves commercial properties across Calgary, Airdrie, Okotoks, Chestermere, Strathmore, Red Deer, Lethbridge, Medicine Hat, Brooks, and High River.
Our Process
CPR Group's HAAG Certified Inspectors assess the membrane condition, drainage slope, flashing terminations, rooftop penetrations, and the condition of insulation and deck beneath. The inspection produces a written scope, photos, and measurements, the same documentation required by insurance adjusters and property managers.
Not every commercial roof needs the same membrane. TPO works on warehouses where reflectivity matters. SBS modified bitumen performs well on roofs with foot traffic. EPDM handles Calgary's temperature extremes. Standing seam metal makes sense where long service life and hail resistance are priorities. CPR Group recommends based on the building, not the margin.
Commercial roof failures almost always start at the edge, the penetration, or the seam, not the middle of the field. CPR Group details every termination, curb, and flashing to the manufacturer's specification and Alberta building code requirements.
CPR Group provides photos, warranty paperwork, and a maintenance recommendation at close-out. That documentation matters for building owners, property managers, strata boards, and insurance records.

FAQ
Find answers to commonly asked questions about our commercial roofing process.
CPR Group installs and repairs TPO, EPDM, SBS modified bitumen, and standing seam metal roofing systems for commercial properties across Calgary. Our crew also maintains and repairs existing built-up tar and gravel roofs on older commercial buildings.
Dark membrane colours absorb heat and can raise summer cooling loads. White TPO reflects solar radiation and reduces cooling demand on Calgary commercial buildings during peak summer temperatures. Insulation R-value matters more than membrane colour in winter, CPR Group can inspect your existing insulation during the roof assessment.
CPR Group Ltd has operated as a Calgary roofing contractor since 2007, 18+ years of continuous commercial and residential roofing across Calgary and Southern Alberta.
CPR Group responds to commercial roofing emergencies with same-day or next-day assessments in most cases, followed by temporary weatherproofing (tarps, board-ups, or temporary patches) and a permanent repair plan with documentation for your insurance file.
CPR Group serves commercial properties across Calgary, Lethbridge, Medicine Hat, Red Deer, Airdrie, Okotoks, Brooks, Chestermere, High River, and Strathmore.
Yes. CPR Group offers scheduled preventive maintenance, membrane inspections, drain cleaning, seam and flashing checks, and penetration assessments, on commercial roofs across Calgary. Scheduled maintenance typically extends membrane life and catches small failures before they become full replacements.
Restaurant exhaust is hard on EPDM and TPO, which can degrade from grease and fryer oils over time. PVC single-ply membranes resist chemical and grease exposure better than EPDM or TPO, making them the more durable long-term choice for kitchens and food-service buildings. CPR Group can assess your existing roof and recommend a system matched to your exhaust layout and building use.
Standing seam metal roofing can reduce insurance premiums by 15-25% due to superior hail resistance. Ask your insurance carrier about potential savings when comparing material options.
