A leak can start on one unit's section and show up in the home next door. 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/). ## Old Oakville, Bronte and the newer north: Oakville Oakville began as a Lake Ontario port. William Chisholm's shipyard worked Sixteen Mile Creek into the 1840s, grain and lumber went out by schooner and rail, and shipbuilding continued into the late twentieth century. In the 1900s oil refineries and the Ford Motor Company's Canadian headquarters and plant added industry near the rail lines and the QEW. Old Oakville became a heritage conservation district in 1981. Census data show about 27% of homes were built before 1981 and 38% in 2001 or later. Old Oakville, Kerr Village and Bronte have older brick and stone buildings, shops and houses, where flat roofs over rear additions, dormers and storefronts are frequent. Eastlake, Clearview and College Park lie between the old core and the newer north. Glen Abbey, River Oaks, Palermo and West Oak Trails are newer, with townhouse blocks and detached homes that commonly use membrane roofs over garages and low-slope sections. The Uptown Core along Trafalgar Road and the employment areas near the QEW include plazas, offices and manufacturing buildings with large low-slope roofs. ## Oakville weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.
