Expert installation of TPO, PVC, and EPDM single-ply membrane roofing systems. The right solution for every flat and low-slope commercial roof.
Book Free AssessmentEach membrane type excels in different applications
Thermoplastic polyolefin—the modern standard for commercial roofing. Energy-efficient white surface with heat-welded seams.
Polyvinyl chloride—ideal for environments with chemical exposure. The premium choice for restaurants and industrial facilities.
Ethylene propylene diene monomer—50+ year track record. Exceptional cold-weather flexibility and longevity.
Industry-leading performance for flat and low-slope roofs
White TPO and PVC membranes reflect up to 90% of solar heat, dramatically reducing cooling costs and HVAC loads.
Heat-welded seams are stronger than the membrane itself. No seam failures means no leaks.
Reinforced membranes withstand foot traffic, rooftop equipment, and mechanical impact.
Minimal maintenance requirements—periodic inspections and drain clearing is typically all that's needed.
No Dollar Limit warranties from manufacturers cover materials, labor, and consequential damages.
From small retail shops to million-square-foot warehouses, membrane systems scale to any project.
CMP Roofing provides expert membrane roofing installation throughout Greater Calgary. As certified applicators for major manufacturers, we deliver installations backed by the industry's strongest warranties.
We're certified installers for Carlisle, Firestone, GAF, Johns Manville, and Versico. This means factory-trained crews, proper material specifications, and access to NDL warranty programs.
Choosing the right membrane depends on your building's specific needs:
Two other flat-roof systems are worth comparing, especially on older Calgary buildings: two-ply SBS modified bitumen, which adds multi-layer redundancy and handles heavy foot traffic, and built-up roofing (BUR), the tar-and-gravel system still found on many older warehouses and schools.
Membrane roofing is more than just the surface. We install complete systems including:
Protect your investment with our roof maintenance programs. Semi-annual inspections, drain clearing, and minor repairs keep your roof performing and maintain warranty compliance.
Calgary roofs deal with deep cold snaps, chinook freeze-thaw swings, heavy spring snow and summer hail. We specify each membrane for those conditions: thicker membranes over high-density cover board on hail-exposed roofs, tapered insulation so meltwater reaches drains instead of refreezing, and edge and flashing details built to resist wind uplift.

Common questions about commercial membrane roofing
TPO and PVC typically last 25-30+ years with proper installation and maintenance. EPDM routinely exceeds 30 years and many installations from the 1970s are still performing.
Both are heat-welded thermoplastics with similar performance. PVC is chemically resistant and self-extinguishing, which makes it the preferred choice for restaurants and chemical facilities. TPO offers excellent value for most other applications.
Often yes, if your existing roof is in reasonable condition. Overlay installations save tear-off costs and reduce landfill waste. We'll evaluate during inspection.
As certified installers, we offer manufacturer NDL (No Dollar Limit) warranties from 10-30 years covering materials, labor, and consequential damages. These are backed directly by manufacturers.
For most buildings TPO offers the best balance of cost and performance. PVC is the choice for restaurants and facilities with grease or chemical exposure, and EPDM suits owners who prioritize cold-weather flexibility and simple repairs. We recommend a system after assessing your roof, drainage and budget.
Single-ply recovers typically range from about $4.00 to $9.00 per sq ft and full tear-off replacements from about $6.00 to $14.00 per sq ft, depending on the membrane, insulation and roof complexity. We confirm pricing after an on-site assessment.
