Flat roof repair in Oakville

Flat roof services in Oakville

Townhouses and row houses are common in Oakville, and their flat roof sections often span several units. 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 with EPDM, TPO, PVC or modified bitumen, and fix the drainage so water does not sit on the new membrane. Owners and property managers also book inspections and maintenance visits.

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. They show what a flat roof in Oakville has to handle.

• 1.1 kPaGround snow load (about 23 lb per sq ft)
• 0.4 kPaRain load added to snow (Sr)
• 23 mmRain in a 15-minute storm (design value)
• 97 mmRain in one day, 1-in-50-year storm
• -18 °CJanuary design temperature
• 3,760Heating degree-days per year
• 0.47 kPaHourly wind pressure, 1-in-50-year

That snow load is about 1.2 times the Toronto figure. Snow drifts against parapets, walls and rooftop units, and the weight sits on the roof for weeks. Drains that freeze shut leave meltwater nowhere to go.

Short summer storms can still drop 23 mm of rain in 15 minutes, so drains and scuppers have to be clear and sealed.

17% of homes in Oakville are row houses or townhouses. Flat sections often run across several units, so a leak can start on a neighbour's part of the roof or at the joint between two units. See townhouses and row houses.

38% of homes in Oakville were built since 2001, one of the higher shares among the cities we cover. Newer flat roofs rarely fail across the whole membrane; they leak at details first: flashings at rooftop units and terraces, drains and dried-out sealants. A maintenance visit catches those early.
