Flat and low-slope roofs cannot use shingles – they need a continuous, watertight membrane. We install all three of the systems Ottawa buildings rely on, and we help you pick the one that fits your roof, your budget, and how the space is used.
A tough rubber membrane that handles Ottawa's temperature swings and lasts for decades. Great value for homes and low-traffic roofs.
A bright, heat-welded white membrane that reflects sun, seams that are welded rather than glued, and strong energy performance.
Torch- or self-adhered asphalt layers – rugged, redundant, and proven on decades of Ottawa flat roofs.
We build in slope and drainage so water leaves the roof instead of sitting on it.
Heat-welded or fully bonded seams that do not open up like old glued laps.
Careful membrane detailing at walls, drains, curbs, and penetrations – where flat roofs almost always fail.
We match EPDM, TPO, or modified bitumen to your roof rather than installing whatever is on the truck.
Choosing a flat-roof system is not about brand loyalty, it is about the roof in front of us. A low-traffic home addition, a bright commercial roof that bakes in the sun, and a rooftop that gets walked on regularly all call for different membranes. We walk your roof, check the slope and drainage, and recommend EPDM, TPO, or modified bitumen based on what will actually last there.
Flat roofs almost never fail in the middle of the field – they fail at the edges, the seams, the drains, and the penetrations. That is where we spend our time: building positive slope to the drains, welding or fully bonding the seams, and detailing the flashing at every wall, curb, vent, and drain so water has nowhere to sneak in.
Flat roofing is where a lot of Ottawa roofers are thin, and it is a core part of what we do. Whether it is a flat section over an addition, a whole low-slope house, or a commercial building, you get certified installers who put down membrane roofs every week – not once a season.
It depends on the roof. EPDM (black rubber) is durable and great value. TPO (white, heat-welded) reflects sun and can lower cooling costs. Modified bitumen is rugged and redundant, good where a roof takes abuse. We look at your roof's slope, drainage, foot traffic, and budget, then recommend the best fit.
A properly installed EPDM, TPO, or modified bitumen roof typically lasts 20 to 30 years in Ottawa. Drainage and flashing details matter more than the brand – which is exactly where we focus.
Often, yes. If the membrane has life left and the problem is a seam, a flashing, or a drain, we repair it. If the membrane is failing across the roof, we will tell you straight that replacement is the better spend.
Yes. We install and repair flat and low-slope membrane roofs on commercial buildings, additions, and multi-unit properties across Ottawa, and can schedule around your operating hours.
