Home protection
Your roof is the first line of defence for everything under it. We strip to the deck, inspect for rot, and rebuild the system properly so water stays outside where it belongs.

Ventilation
A roof has to breathe as well as shed water
Ventilation matters as much as the shingles. On roughly 90% of the roofs we do, the right answer is Maximum sloped-roof ventilators (ventilation-maximum.com) — we calculate how many your roof needs from its square footage so warm, moist air escapes the attic instead of condensing under the deck. Ridge venting is the exception: we install it on homes with cathedral ceilings that were framed for it.
- Maximum roof vents as our standard exhaust
- Vent count calculated from your roof square footage
- Ridge venting where a cathedral ceiling is framed for it
- Helps prevent ice dams and attic moisture
How it works
What happens, step by step.
No surprises and no vague answers — here's exactly how the job runs from first call to final paperwork.
- 01
Free assessment
Rob inspects your roof in person — on the roof, not from the driveway — and discusses and shows you what he finds.
- 02
Detailed quote
An itemized quote with product links and colour selection, so you know exactly what you're paying for.
- 03
Tear-off & deck check
Old shingles come off and the deck is inspected. Any rot is replaced with new plywood before we build back.
- 04
Underlayment
A minimum of 6 ft of ice-and-water shield at the eaves and 3 ft in valleys where there are any, with synthetic underlayment over the remainder. The rare very low-slope roof gets 100% ice-and-water shield.
- 05
Shingles & ventilation
Duration shingles installed to spec, with proper ventilation calculated based on your roof square footage. We utilize Maximum roof vents and ridge venting for cathedral ceilings so the attic breathes properly.
- 06
Cleanup & records
Meticulous cleanup, then an email with photos of the finished roof, your workmanship and shingle warranty information and receipt.

91 reviews. One word keeps coming up: trust.
I am very impressed with this company's professionalism and attention to detail. The work was done on time, and the quality of service was superb. I also liked that his quote was on target and extras were discussed and agreed to before going ahead with work. Extremely honest, and you can tell he cares about his customers. I fully recommend this company.
Rob was a pleasure to work with from the start. He was friendly, professional, and answered all our questions. Our roof was completed in a timely manner, and the site was thoroughly cleaned upon completion. We strongly recommend Rob for your roofing needs and look forward to having him do our jobs in the future!
Rob did an absolutely amazing job on our roof. From the second he came to do our quote, he was a pleasure to deal with. Very knowledgeable and answered all our questions. They worked fast and efficiently, and left our space spotless upon completion. Highly recommended!
Rob and his crew were outstanding in every way. They were very conscientious and meticulous in their work and always cleaned everything up before leaving each night. On the last day they spent more than one hour cleaning up. They take great pride in their work and the final product is a reflection of this fine work. Not only was their work excellent, their prices were much more reasonable than their competitors. Differing from most other roofing companies, Rob, the owner, worked on the roof right beside his crew. This makes a real difference.
Great job Rob. Roof looks fantastic. Appreciate your efficiency and workmanship. Clean-up was great. Anyone looking for a new roof should be talking to Rob's Quality Roofing first.
Rob's Roofing was professional in every way. Honest and respectful of each home owner's concerns and needs (4 in one town house). I wouldn't hesitate to recommend this team of hard workers. I'm very pleased with the result.
Good questions
Answers, straight from Rob.
The questions homeowners ask most about roof replacement. Still unsure? Call Rob directly — he'd rather you understand exactly what you're paying for.
613-223-6467How do I tell when an asphalt shingle roof needs to be replaced?
If your shingles are starting to curl, crack, raise in the wind (this means your seals are broken) or lose granules, it's time to start thinking about replacing your roof. Some of these signs are hard to spot from the ground. If you're not sure of the condition, call Rob — a roof replacement estimate is always free.
If my roof has a leak, does that mean I need to replace all of it?
Not necessarily. If your roof is still in good shape, repairing the leak should fix the problem. If the roof is in poor shape, repairing the leak could cause more damage than it solves — in that case a replacement may be the better option. An inspection tells us which.
Is it okay to put new shingles over old ones?
No. After the old shingles are removed, the roofer should inspect your roof deck for rot. If rot is found, new plywood needs to be installed — it's unsafe to leave rot on a roof deck. Laying new shingles over old ones skips this critical step.
What's the best underlayment to put under new shingles?
We install a minimum of 6 ft of ice-and-water shield at the eaves, plus 3 ft in valleys where there are any, with synthetic underlayment over the remainder. The rare exception is a very low-slope roof, which should have 100% ice-and-water shield.
