A leak can start on one unit's section and show up in the home next door. Its design snow load is among the lightest of the cities on this site, so freeze–thaw and summer storms do more damage than snow weight. 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/). ## Bay Ridges to Seaton: Pickering's three waves Pickering was farmland, hamlets and Quaker settlement from the early 1800s. Two communities emerged in the early twentieth century: the Pickering Beach cottages and the Defence Industries Limited munitions plant. Urbanization in the south began after the Second World War. Pickering Nuclear Generating Station, with Pickering A opening in 1971, is the city's largest employer. Census figures show about 31% of homes were built before 1981 and 22% in 2001 or later. South Pickering holds most of the older stock. Bay Ridges, Rosebank, Dunbarton and Village East are older, and houses and low-rise buildings there often have flat roofs over additions and garages. Pickering Town Centre is a two-storey mall with large low-slope commercial roofs, and new condominium buildings are going up near the GO station. The Brock Industrial area and the lands around the nuclear station include industrial buildings with wide flat roofs. Seaton, the planned northern community, is still in early stages, so most of its roofs are new. ## Pickering weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.
