Single-ply membranes are the workhorse of modern commercial flat roofing. As certified TPO and EPDM installers, we help London building owners choose the right membrane and install it to last.
TPO (thermoplastic polyolefin) is a bright, reflective membrane that lowers cooling costs in summer and resists punctures and tears. Its heat-welded seams create a continuous watertight surface — ideal for warehouses, retail plazas, and offices. See our guide to TPO roof lifespan in Ontario.
EPDM (rubber membrane) is proven, flexible, and extremely durable in cold climates — a strong fit for London's freeze-thaw winters. It's a cost-effective, long-lived option for many low-slope roofs.
It depends on roof size, sun exposure, foot traffic, insulation, and budget. During your free assessment we'll recommend the system that gives you the best cost-per-year — not just the cheapest install. Planning a full flat roof replacement? Membrane choice is step one.
