On a Richmond Hill house the flat roof is the garage, the front portico or the sunroom — small, ignored, and usually the first thing to leak. Along Yonge and Highway 7 it's the roof over your business.(416) 846-3797Or send the form and we'll call you back.

Most Richmond Hill homes have at least one flat section: a three-car garage in Bayview Hill, a portico over the front door, a rear sunroom or addition on an older Doncrest house. The builder covered these with a basic membrane that gets none of the attention the shingled roof above it gets, and the transition where the flat meets the pitched roof is almost always the leak. Then there's the commercial strip — plazas and office buildings along Yonge Street, and industrial units near Highway 7 and Leslie — with large low-slope roofs where a blocked scupper after a storm or a failed seam at a rooftop unit means water in a tenant's ceiling.
We look at the whole flat roof — where the water goes, whether it ponds, how the edges and the transition to the sloped roof were built. A sound membrane with one bad seam or one failed curb gets a bonded repair that becomes part of the roof. A surface that's cracked, blistered or been patched twice already gets replaced: layers off, deck checked, tapered insulation to give it slope it never had, new membrane, new metal at the edges and the transition. On commercial units we schedule around your tenants and keep the work off the busiest hours.
Repair when the leak is at one clear point on a roof that's otherwise holding. Replace when water sits for days after rain, when the surface has gone brittle or alligatored, or when it's the original roof on a 20-year-old garage that has never been touched.
Yes — plazas along Yonge, office units, and industrial buildings around Highway 7 and Leslie. We inspect the drains, seams and rooftop unit curbs and quote the repair or replacement in writing.
Usually, yes. The transition is the problem, not the field of the roof. It needs proper step flashing and membrane overlap into the sloped roof above, and that joint is the core of any repair we do there.
Yes. It's a small area that fails before the main roof and leaks into the garage ceiling and the shared wall. It's a modest job that doesn't have to wait for a full roof replacement.
