A flat roof over a Toronto home takes more punishment than most people realize. Snow load, ice, standing water and summer heat all work on it year after year. That is why quality roofing on a low-slope deck is a specialist job. At Flat Roofs Toronto, residential flat roof installation is what we do every day, on rear roofs, garages, additions and row house decks across the city and the GTA.

 

Where Residential Flat Roofs Are Found

Toronto is full of homes with flat or low-slope sections. Row houses often have a flat rear roof, laneway garages sit under low-slope decks, and many rear additions and dormers use a flat roof as well. These roofs are small compared with commercial buildings, but the details are demanding. Flashing must tie into brick walls and parapets, drains must be clear and correctly placed, and every penetration needs to be sealed properly.

 

Choosing the Right System

There is no single best membrane for every house. We walk your roof first, then recommend the system that suits the deck, the exposure and your budget:

  • 2-ply modified bitumen torch-down, two reinforced layers torched into one continuous surface
  • Cold-ply with ceramic granules, applied with adhesive and with no open flame on the deck
  • EPDM rubber, a flexible membrane that handles freeze-thaw cycles and patches cleanly
  • TPO single-ply, a reflective white membrane with heat-welded seams

Each has its place, and we explain the trade-offs in plain language before any work begins.

 

How Our Installation Process Works

Every job follows the same five steps. You call or send your details, we inspect the roof and photograph what we find, and you receive a detailed written quote with the scope, system, materials and price. Once you approve, we schedule the work, protect your property and keep you updated. At the end we walk the finished roof with you and hand over your warranty paperwork.

 

Slope, Drainage and Detail Work

Most flat roof failures start with water that has nowhere to go. Where a deck is flat or sagging, we can frame a lumbered slope to move water toward the drains before installing the new system. We also finish the small details that decide whether a roof leaks, including parapet flashing, drain connections, vents and edge metal.

 

Warranties and Honest Pricing

A properly installed flat roof in Toronto generally lasts 20 to 30 years. Full replacements typically run about $8 to $15 per square foot, depending on size, material and complexity. Our quotes are free and carry no obligation, so you see the real number before deciding anything. Materials are covered by manufacturer warranties, and our installation is covered by a workmanship warranty.
