Built for heavy snow loads." url: https://flat-roof-repair.ca/locations/barrie/ last_updated: 2026-10-23 --- # Flat roof repair in Barrie We repair, replace and maintain flat roofs in Barrie: 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 Barrie Barrie 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. Barrie has one of the five heaviest design snow loads of the 40 cities on this site, so drains and parapet flashings get extra attention. 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/). ## Fast growth around Kempenfelt Bay in Barrie Barrie's population rose from 38,423 in 1981 to 147,829 in 2021, a growth tied to its role as a commuter city for Toronto. It annexed land from Innisfil in 2010. Downtown Dunlop Street was rebuilt after fires between 1870 and 1890, and newer areas such as Ardagh Bluffs, Painswick and Park Place were built much later. Census data shows only about 29% of homes were built before 1981, and about 33% after 2001. That makes Barrie younger than most Ontario cities. In the newest areas townhouse blocks and condominiums commonly have membrane roofs over flat or low-slope sections, and these roofs are now reaching an age where seams and flashings need attention. The older stock near Allandale and downtown includes brick houses with flat rear additions, and commercial buildings on Dunlop Street. Large retail centres and the institutional roofs of schools, Georgian College and the hospital add substantial low-slope areas. ## Barrie weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.

If you clear snow from a flat roof, leave a few centimetres on the membrane so shovels do not cut it. ## Starting prices in Barrie | Item | Starting price | |---|---| | [Small leak repair (patch, seam or puncture)](https://flat-roof-repair.ca/services/flat-roof-leak-repair/) | from $350 per repair | | [Flashing repair or replacement](https://flat-roof-repair.ca/services/flashing-and-seam-repair/) | from $500 per repair | | [Maintenance visit (drains, seams, flashings, photos)](https://flat-roof-repair.ca/services/flat-roof-maintenance/) | from $295 per visit | Starting prices in CAD before 13% HST, based on typical Ontario contractor rates (mostly Toronto and the GTA).

Prices in Barrie depend on access, layers to remove and the membrane. See [pricing](https://flat-roof-repair.ca/pricing/). **Should I clear snow off a flat roof in Barrie?** Only if the snow is deep and wet, drifts are building against walls or units, or the building shows signs of stress. Use a plastic shovel, leave a layer on the membrane and never use picks or salt. If in doubt, ask a professional. **Do I need a permit to replace a flat roof in Barrie?** City: roof alterations (dormers, skylights, solar panels) need a permit; re-shingling needs none if the roofing weight does not increase. That wording is about shingles, so ask how it applies to a flat roof membrane. Rules can change, so confirm with the building department before you start. See [re-roofing permits in Ontario](https://flat-roof-repair.ca/guides/re-roofing-permits-ontario/). **My Barrie home is fairly new. Why is the flat roof leaking already?** On newer roofs leaks usually start at a detail, not the membrane: a terrace door, a rooftop unit curb, a drain or a sealant joint. Those are repairable. See [flashing leaks](https://flat-roof-repair.ca/problems/flashing-leaks/). **Do you also work near Barrie?** Yes, including Orillia, Collingwood, Newmarket and the rest of central Ontario.
