    When You Need Commercial Roofing

    A compromised commercial roof threatens your inventory, equipment, and daily operations. You need a commercial roofing expert when your flat roof is experiencing ponding water, open seams, or membrane blistering. We also provide new installations for commercial construction projects.

    Signs Your Flat Roof Needs Attention

    • 01
      Ponding WaterWater that stays on the roof 48 hours after rain indicates poor drainage or sagging insulation.
    • 02
      Open SeamsAdhesives break down over time, allowing water to penetrate between membrane panels.
    • 03
      Blistering or AlligatoringBubbles in the membrane or a cracked, dry surface mean the material is failing.

    Why It Suits Saskatchewan

    • Membranes chosen for flexibility in -40°C weather to prevent winter cracking.
    • Proper insulation tapering to ensure drainage during heavy spring snowmelt.
    • High wind-uplift resistance to withstand open prairie gusts.
    • Energy-efficient options (like white TPO) to reduce summer cooling costs.

    Materials We Use for Commercial Roofing

    We install industry-leading single-ply membrane systems, primarily TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer). TPO is highly reflective, energy-efficient, and features incredibly strong heat-welded seams. EPDM is a durable rubber roofing system known for its exceptional flexibility in freezing temperatures. For heavy-traffic roofs, we also offer multi-ply Modified Bitumen systems. We pair these membranes with high-R-value rigid foam insulation (Polyiso) tapered perfectly to guarantee positive drainage.

    What It Costs

    Estimated Cost: $8 – $16 per sq. ft.

    *This is a rough estimate for full flat roof replacement. Cost depends heavily on insulation requirements, tear-off depth, and number of penetrations.

    Commercial roofing costs vary widely. A simple layover on a clean deck will be on the lower end, while a full tear-off requiring new tapered insulation to fix drainage issues will be on the higher end. We provide detailed, honest bids that outline all materials, labor, and safety equipment, ensuring absolutely no surprises. For general pricing information, see our Saskatchewan Roofing Cost Guide.
