Toronto roofs don't fail the same way twice. A 1910 semi in Roncesvalles, a 1955 bungalow in Scarborough and a 2005 townhouse in Etobicoke each leak for different reasons — and each gets a different fix.(416) 846-3797Or send the form and we'll call you back.

Much of the west end and the east end was built before 1930: semi-detached and row houses with low-slope or flat roofs, brick party walls and chimneys that have outlived several furnaces. In Roncesvalles, Leslieville and The Junction the typical call is a flat roof that has been patched over three or four times, with water finding the seams around the chimney or the neighbour's parapet. Further out, Etobicoke and Scarborough are mostly post-war bungalows and split-levels with straightforward shingle roofs — easier to replace, but old enough that the deck under the shingles often needs attention too. North York and East York sit somewhere between, with 1950s houses and newer rebuilds side by side.
Toronto weather is hard on both types. Freeze-thaw cycles through February and March open up seams on flat roofs and lift shingles that were already brittle. Ice damming along the eaves pushes meltwater back under the first courses. Summer brings the opposite problem — heat that bakes tar and cracks older membranes — and the storms that come off the lake in late summer test every flashing on the house. Most leaks we see in the city started as a small opening a season or two earlier.
Water that gets past the roof rarely stops there. It runs down inside walls, sits on top of the foundation and shows up as damp in the basement — which is why we handle the roof, the chimney, the masonry and the foundation as one job. On a century home that means one crew, one quote and one person responsible for where the water actually goes. The owner inspects the property himself and writes the quote; there is no salesperson between you and the person who will do the work.
There's no honest flat number. The price depends on the roof's size and pitch, whether it's shingle or flat, how many layers are on it now, the condition of the deck underneath, and how much flashing and chimney work is needed. A semi with a simple flat roof and a two-storey detached with valleys and dormers are very different jobs. We come out, look at everything, and give you a written, itemized quote — no obligation.
Yes — flat and low-slope roofs on semis and rowhouses are a large part of our Toronto work. Because you share a wall with your neighbour, the details at the party wall and parapet matter as much as the field of the roof. We repair sections when the membrane is sound and replace the whole surface when it isn't.
For a like-for-like re-roof — new shingles or a new membrane on the existing structure — Toronto normally does not require a building permit. A permit is needed when the structure changes: raising the roof, adding a dormer, or replacing rafters or the deck. We tell you before work starts if your job falls into that category.
