After
During Project
Is it time to replace your roof?
The warning signs are usually there before things get serious:
- Lifted, curled, or ruffled shingles
- Heavy granule loss collecting in the eavestroughs
- Moisture stains on interior ceilings
- A roof that’s been through 15–20+ Ontario winters
About half the time, homeowners call us because they’ve noticed something. The other half, we spot the need when we come out to quote. Either way, you’ll get a straight answer — if a repair will solve the problem, we’ll say so.
What we look at before quoting
Every estimate starts with a visit to your home. We get up on the roof ourselves — an accurate quote means seeing the actual condition of the decking and ventilation system, not guessing from satellite imagery.
If we find decking that needs attention or ventilation that doesn’t meet current code, we flag it upfront and include it in the scope. Inadequate ventilation can void your manufacturer warranty — better to know before the job starts.
How it works
1
Free estimate
We come to you, get up on the roof, and provide a written quote. Anything worth flagging gets factored into the scope upfront.
2
Material selection
We walk you through shingle options and grades and help you find what fits your home and budget.
3
Tear-off & installation
Old materials come off, decking is addressed, ventilation is brought up to code, and your new roof is installed to manufacturer specs.
4
Final walkthrough
Our own team does a final check before we call the job done. Your property is cleaned up and you receive your warranty documentation.
Backed by warranties that hold
Every installation comes with two layers of protection:
- 10-year workmanship warranty — If something goes wrong because of how the roof was installed, it’s on us.
- Manufacturer product warranty (lifetime) — We’re factory-certified to install BP, GAF, and Polyglass products, which keeps your manufacturer warranty intact.
Certified, insured, and accountable
If an uninsured contractor is injured on your property, that liability can fall on you as the homeowner. Chouinard Bros is:
- Fully insured with liability coverage
- WSIB registered
- Working-at-Heights certified
- GAF Certified Contractor
- Factory-certified BP and Polyglass installer
Financing Options Available
A roof replacement is a significant expense and the timing isn’t always ideal. We offer flexible financing plans so you can protect your home now without putting everything on a credit card. Ask us about options when you reach out.
FAQ
Wondering about the process? We've got answers ready!
Most residential shingle replacements in the GTA range from $8,000 to $20,000+ depending on roof size, pitch, material grade, and what we find on the decking when we get up there. An on-site estimate is the only way to give you an accurate number.
Roof size and pitch, shingle grade, decking condition, whether ventilation needs updating, and roofline complexity (valleys, skylights, dormers) are the main drivers.
Yes — we offer flexible financing plans that let you spread the cost into manageable monthly payments. Ask us when you book your estimate.
Insurance typically covers sudden damage from storms, wind, or hail — not general wear over time. We can provide a written assessment to support a claim if one applies to your situation.
Document visible damage, contact your insurer to open a claim, and we can provide a written damage assessment and quote to support the adjuster’s review. The sooner you act after a storm, the cleaner the process.
Contact us as soon as possible — we’ll assess the roof, provide a written quote, and document the current condition, which gives you something concrete to work with in your conversations with the insurer.
Localized damage is usually repairable. Widespread granule loss, multiple failed areas, or a roof already 15–20 years old often makes replacement the more cost-effective long-term answer — we’ll tell you honestly which one applies.
Lifted or curled shingles, heavy granule loss in the eavestroughs, moisture stains on interior ceilings, and shingles that appear to be holding moisture (they look darker or heavier than the surrounding area).
A well-maintained laminate shingle roof typically performs for 20–30 years in Ontario — though ventilation quality, sun exposure, and installation workmanship all have a significant effect on that number.
Tear-off of existing shingles and underlayment, decking inspection and repair, ventilation update if needed, new underlayment including ice and water shield, new shingles and ridge cap, flashing, full cleanup, and a final walkthrough.
We always remove the old shingles — going over top adds weight, traps moisture, prevents a proper decking inspection, and voids most manufacturer warranties.
It’s a self-adhering waterproof membrane installed under the shingles at the eaves and in valleys — the areas most vulnerable to ice damming. In Toronto’s climate, it’s not optional.
Metal roofing lasts 50+ years and performs well in snow and wind, but the upfront cost is significantly higher than shingles — whether it’s worth it depends on how long you plan to stay in the home and your budget.
Most residential shingle replacements are completed in one to two days. Flat roofing and custom projects may take longer, and weather can shift the schedule.
Yes — we work year-round when needed. The practical consideration is that shingle sealant strips require warmth to fully activate, so a cold-weather install may take until spring to fully seal.
Ask for proof of liability insurance and WSIB coverage before anyone gets on your roof — a legitimate contractor will have no hesitation providing both. Be cautious of door-to-door solicitation after storms and unusually low quotes.
A straight shingle-for-shingle replacement generally does not require a permit in Toronto — structural changes or certain commercial projects may. We’ll flag it if your project requires one.
You should receive a workmanship warranty from the contractor (ours is 10 years) and a manufacturer product warranty on the shingles — both require proper installation to be valid, which is why certifications matter.
Keep eavestroughs clean, watch for storm damage, and book a roof check every five years after the 10-year mark — caulking around flashings starts to crack around year seven, and catching it early is far cheaper than dealing with a leak.
We use magnetic nail sweeps as part of our cleanup — and we’ll always suggest you do a walk of the yard yourself too, especially around landscaping where magnets have limits.
