Drains and flashings for heavy summer storms." url: https://flat-roof-repair.ca/locations/vaughan/ last_updated: 2026-10-23 --- # Flat roof repair in Vaughan We repair, replace and maintain flat roofs in Vaughan: houses, garages and additions, condo and apartment buildings, plazas, offices and warehouses. Send photos and a few details for a written quote. ## Flat roof services in Vaughan Vaughan has a lot of newer housing, and on newer flat roofs leaks usually start at details rather than the whole membrane: a terrace door, a rooftop unit or a drain on a roof that is otherwise sound. We find where the water gets in, fix that spot and tell you how much life the rest of the roof has. When a roof is past repair, we [replace it](https://flat-roof-repair.ca/services/flat-roof-replacement/) with EPDM, TPO, PVC or modified bitumen, and fix the [drainage](https://flat-roof-repair.ca/services/roof-drains-and-scuppers/) so water does not sit on the new membrane. Owners and property managers also book [inspections](https://flat-roof-repair.ca/services/flat-roof-inspection/) and [maintenance visits](https://flat-roof-repair.ca/services/flat-roof-maintenance/). ## Villages, highways and warehouses in Vaughan Vaughan was a farming township with mills until the postwar years. Thornhill is its oldest hamlet, with a sawmill from 1801 and a grist mill from 1815, and Woodbridge and Kleinburg grew as village cores. Highway 400 was completed to Barrie in 1951, and the population reached about 16,000 by 1960. Census data show only about 8% of homes were built before 1981, and about 50% in 2001 or later. That makes Vaughan a mostly newer building stock. Around Maple, Concord and Woodbridge you find subdivisions and townhouse blocks from the past few decades, where membrane roofs over garages, porches and flat sections are typical. The heritage main streets of Thornhill, Woodbridge and Kleinburg have older brick buildings that often carry flat roofs behind the front facade. Vaughan also has a large employment base: manufacturing makes up about 22% of jobs, and warehouse, distribution and rail-related buildings, such as those of employers like UPS Canada and Canadian National Railway, have extensive low-slope roofs. The Vaughan Metropolitan Centre around Highway 7 and Jane Street adds new towers with terraces and podium roofs. ## Vaughan weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.

See [flashing leaks](https://flat-roof-repair.ca/problems/flashing-leaks/) and [clogged drains](https://flat-roof-repair.ca/problems/clogged-drains/). **Do I need a permit to replace a flat roof in Vaughan?** Check with the Vaughan building department.
