Roofing contractor in Mississauga

Big roofs, open sky, and a lot of wind off the lake

We have been working on Mississauga roofs for the better part of our 20-plus years in the trade, and the housing stock explains most of what we find. Mississauga is mostly subdivision stock: wide two-storeys from the eighties and nineties with large uninterrupted roof planes, plus a lot of newer builds with complicated hip-and-valley layouts and steep front elevations you can see from the street. Those big planes catch weather. Between Lakeshore and the QEW you get wind coming off Lake Ontario with nothing to slow it down, and on an aging roof that means lifted tabs along the exposed edges and rakes long before the middle of the roof looks tired.

The complicated newer roofs fail differently. More valleys, more sidewall transitions, more skylights and dormers means more flashing, and flashing is where roofs leak. We see plenty of ten-year-old Mississauga roofs with perfectly good shingles and a valley detail that was never done properly.

Freeze-thaw does its work here too, and so does ice damming at the eaves — especially over garages and cantilevered bonus rooms, where the space below is cold and badly insulated. Those spots stay frozen while the rest of the roof drains, and the trapped water backs up under the shingle courses.

What a Mississauga call usually sounds like

Often it's the garage or the front hall: "there's a wet patch on the garage ceiling drywall" or "water came down the inside of the front window after the freeze last week." Sometimes it's cosmetic first — "the shingles look patchy and dark in strips from the driveway" — which usually means granule loss, not staining.

And after a real windstorm the phone is all one call: shingles in the yard, in the pool, up against the fence. We'll come out, count what's actually gone, look at whether the rest of the field still has any seal left, and give you a real read on whether this is a repair year or a replacement year.

When a repair is the smarter buy

A twelve-year-old Mississauga roof that lost twenty shingles off one exposed corner does not need to come off. Match the shingles, fix the flashing detail that was probably part of the problem, and you get years out of it. We will tell you that even though the bigger job is the bigger invoice — the referrals are worth more to us than one oversold roof.

The flip side: if the seal is gone across the whole field, the next windstorm will find another corner, then another. At that point repairs are a payment plan for a roof you don't get to keep. We'll spell out both options in writing with the materials named so you can compare quotes properly.

What gets installed, start to finish

Full tear-off, deck inspection and sheathing replacement where it's soft, ice and water shield along the eaves and through every valley, synthetic underlay, new drip edge and starter, then architectural shingles nailed to spec. New step flashing where the roof meets brick, new counter flashing at chimneys, new pipe boots, and ridge venting balanced against soffit intake so the attic stays dry in winter.

For flat sections — additions, garage roofs, low-slope commercial off Dixie or Britannia — two-ply modified bitumen with the drains, scuppers and parapet terminations detailed before the field membrane goes down. Every job ends the same way: eavestrough cleared or replaced, downspouts running away from the foundation, and a magnet sweep of the driveway and lawn so nobody picks up a nail with a tire.
