About Pro Alliance Roofing
Pro Alliance Roofing is a Scarborough-based roofing company built on three principles that rarely come together in this trade: quality, respect, and honesty. We handle the full exterior of your home — architectural shingle and slate, flat roofing, cedar, eavestrough, siding, soffit and fascia — with the kind of craftsmanship that holds up through every Ontario season. Every project is treated as if it were our own home: premium materials, meticulous installation, and a team that communicates clearly from the first estimate to the final inspection. The result is a roof that performs for decades and a process that leaves you confident you chose the right people.

Why Choose Us
Customer Reviews
“Shay and his team were incredibly thorough. They found the actual source of our leak that two other roofers completely missed. Honest, professional, and fairly priced.”
Michael T. — North York
“I appreciated that they gave me an honest assessment. No upselling — they repaired what needed repairing and told me the rest of the roof had years left.”
Sandra M. — Scarborough
We had a persistent leak for 3 years that others couldn’t find. Pro Alliance found the issue in one inspection and had it fixed properly. Can’t recommend them enough.
David R. — Vaughan
