Send photos and a few details for a written quote. ## Flat roof services in Orillia Many homes in Orillia are rented, so a roof leak is often reported first by a tenant, then handled by a landlord or property manager. Orillia has one of the ten 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/). ## A small lakeside city with an old core in Orillia Orillia developed at the Narrows between Lake Couchiching and Lake Simcoe and became a commercial centre and summer resort once links to Toronto and Georgian Bay opened. It became a city in 1969, and its population grew from 8,774 in 1921 to 24,040 in 1971. Industry has included machinery and automotive parts. Census data shows about 58% of homes were built before 1981, and about 31% before 1961. The downtown, including the Arts District on Peter Street, has older brick buildings where flat roofs sit behind parapets. Houses from the early twentieth century, many near the waterfront at Couchiching Beach Park, often have flat-roofed additions. Schools, institutional buildings and industrial plants of the mid-century decades are typically low-slope. Newer retirement residences and apartment buildings add membrane roofs, and about a quarter of the city's dwellings are in apartment buildings. ## Orillia weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.
