TPO Roofing System Installation in Toronto & the GTA

Energy-efficient thermoplastic roofing for commercial buildings.

TPO Roofing System in Toronto by AZ Roofing

Thermoplastic Polyolefin (TPO) roofing has become the preferred choice for flat and low-slope roofs across Toronto's commercial and residential market. Its white reflective surface reduces cooling costs, its heat-welded seams are stronger than the membrane itself, and its resistance to UV, ozone, and chemical exposure makes it one of the most durable flat roofing options available.

AZ Roofing's flat roofing team has installed TPO systems on everything from residential additions to multi-storey commercial buildings. We work with leading manufacturers including Firestone and GAF to ensure you get the right membrane thickness and warranty for your application.

Our TPO installations include proper drainage planning, tapered insulation where needed, and meticulous attention to penetrations and perimeter details. These are the areas where flat roofs fail — and where our experience shows.

"I highly recommend AZ Roofing. Came at time promised. Family run business. Cleaned up after the repair was completed. Very pleasant to deal with. Understood the urgency of the roof repair, as rain was starting that night. Price for the shingles replaced was very reasonable."

"Darwin was quick, efficient and very professional. He did an assessment and told us exactly what needed to be done. His price was fair and he went out of his way to get the job done before the next rains. He took the time to match the shingles to the existing ones."
