Flat roof repair in Brampton

Flat roof services in Brampton

Brampton 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. 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.

From Flower Town to Bramalea and Springdale: Brampton's building stock

Brampton began as a village laid out in 1834, with a downtown at Main and Queen streets and a name later tied to its greenhouses and nurseries. Dale's Nursery once had 140 greenhouses. In the 1950s Bramalea was developed as a planned new town, and in 1974 Brampton merged with Chinguacousy and Toronto Gore townships. Development of Springdale began in 1991. Census figures show only about 23% of homes were built before 1981, while about 48% date from 2001 or later.

Downtown Brampton has brick commercial blocks and older houses where flat roofs over rear additions and storefronts are common. Bramalea, built from the 1950s onward, has plazas, schools and apartment buildings of an era when low-slope roofing was widely used. Springdale, developed from 1991, brings newer townhouse blocks and detached homes with membrane roofs on porches, garages and flat sections. Brampton is also a logistics and manufacturing city, with distribution centres, an intermodal rail terminal and assembly plants whose very large low-slope roofs need regular inspection.

Brampton 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 Brampton has to handle.

• 1.3 kPaGround snow load (about 27 lb per sq ft)
• 0.4 kPaRain load added to snow (Sr)
• 28 mmRain in a 15-minute storm (design value)
• 119 mmRain in one day, 1-in-50-year storm
• -19 °CJanuary design temperature
• 4,100Heating degree-days per year
• 0.44 kPaHourly wind pressure, 1-in-50-year

That snow load is about 1.4 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.

A design storm can drop 28 mm of rain in 15 minutes. On a flat roof that water has to reach a drain or scupper quickly, so clear drains and sound drain flashings matter as much as the membrane.

Environment and Climate Change Canada climate normals (1991–2020) record about 115 cm of snowfall a year at the Toronto Pearson Int'l Airport station.

13% of homes in Brampton 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.
