How to Choose a Roofing and Exterior Contractor in the GTA: A 2026 Homeowner's Guide
Southern Ontario weather is hard on a house, and the roof, gutters, and siding soak up the worst of it. Freeze, thaw, ice dams, that wind that tears off the lake in February. Whoever you hire to handle all of it is the difference between protection that lasts a decade and protection that lasts closer to thirty years. And there is no shortage of crews out there. Toronto, Hamilton, Burlington, take your pick, and most of the flyers read more or less the same way: great work, solid warranty, in and out fast. Fine. But how do you actually tell apart the roofing and exteriors contractor who does it properly from the one quietly cutting corners you will not spot until the snow melts? A few things, mostly learned the hard way.
Why Getting This Right Actually Matters
Money is the obvious part of it. A GTA roof replacement tends to run from $10,000 to $25,000, and the figure climbs the moment gutters, soffit, fascia, or a fresh window or door get added to the job. Hire badly and the regret arrives fast. Maybe it leaks by the first thaw. Or the manufacturer warranty gets quietly voided and nobody says a word. Then there is the 25-year shingle that somehow starts curling around year eight. Hire well and that same money just goes to work and stays out of your way.
Start With Licensing and Insurance
Before anyone gets up on a ladder, ask to see paperwork. A contractor worth hiring in Ontario will carry liability insurance with at least $2 million in coverage, full WSIB coverage for everyone on the crew, and a registered business with an HST number to back it up. Do not settle for a verbal "oh yeah, we're covered." The good companies hand the documents over the second you ask, no awkwardness about it. We do the same at Infinity Gutters & Exteriors whenever a homeowner wants to see them.
Local Experience Counts for a Lot
Housing around here is a real mix, and roofing it well takes more than a one-size playbook. The older brick semis in Toronto come with steep pitches. Century homes in Hamilton hide awkward valleys you only find once the old roof is off. Custom builds out in Oakville pile on dormer after dormer, and a tight downtown laneway turns simple access into a head-scratcher. A crew that has actually worked Toronto, Hamilton, Burlington, Oakville, and Milton has run into all of it already. That is the kind of mileage we have built up across Southern Ontario since 2014, and this climate teaches you plenty about what an exterior really needs.
Pay Attention to What Sits Under the Shingles
This is usually where a cheap quote starts to unravel. A real roof is not a fresh layer of shingles slapped over the tired old one. The crew should strip off what is there, get a proper look at the sheathing, pull and replace any plywood that has gone soft, and then build the thing back the right way. Drip edge. Ice-and-water shield where the eaves and valleys are. Synthetic underlayment, then the new shingles, vents, and flashing on top. See a quote that jumps straight to "shingle-over"? Ask them what got left out. That same thinking carries right down into your gutters too. A spotless new roof draining into tired, sagging eavestroughs will still push water somewhere it has no business going.
Read the Quote, Then Compare Like for Like
A number scrawled on a business card tells you basically nothing. A real quote should name the shingle brand and model. It should say what underlayment is going down and where the ice-and-water shield sits. Flashing, ventilation, permits, cleanup, the warranty, all of it in plain writing. Once you have two or three, lay them next to each other. Same shingle grade against same shingle grade. Same underlayment. Same ventilation. Same warranty length. That suspiciously low number on one of them usually got low by quietly dropping something, and you generally learn what during the first real downpour.
There Are Two Warranties, Not One
A lot of people hear "warranty" and picture a single thing. Really there are two. One comes from the manufacturer and covers the shingles themselves, often anywhere from 25 to 50 years, and it tends to hold only when a certified crew installs the product to spec. BP Canada and the rest of the major names all operate that way. The other comes from your contractor and covers the actual labour, usually somewhere in the five to fifteen year range. Every install we do at Infinity Gutters comes with both of them, spelled out on paper, no fine print waiting to bite you later.
A Gut Check Before You Sign Anything
Give it fifteen minutes of digging first. Pull up the Google reviews. Check the Better Business Bureau. Nose around a couple of local Facebook groups. One angry one-star is just noise, but the same complaint showing up over and over is worth listening to. After that, the usual tells are worth watching for. Door knockers who happened to be "in the area." A fat deposit wanted up front. A price that magically "expires today." No real office anywhere. No proof of insurance or WSIB when you ask. And anyone hinting you could skip a required permit to shave a few bucks has just told you how they operate.
One Contractor for the Whole Exterior
Since 2014, Infinity Gutters & Exteriors has taken care of roofing, gutters, siding, soffit, fascia, and window and door installs for homes and businesses right across Toronto, Hamilton, Burlington, Oakville, Milton, and the rest of the GTA. There is real value in keeping all of that exterior work with one team. You get a single crew on the hook for how the whole thing fits together, rather than three different outfits pointing fingers the moment something starts to leak. Your roof, your gutters, your windows, your doors, they all have to function as one system anyway, so one team watching over the lot of it just makes life easier.
