A new roof is only as good as the tear-off
A replacement is your one chance to see and fix everything under the shingles, so we never roof over an old roof. We strip it to the deck, replace any wood that is soft or rotted, and start the new roof on a sound, dry base. Skipping that step is how a brand-new roof ends up leaking in five years.
The full system, not just shingles
A roof is a system: ice-and-water shield at the vulnerable edges, underlayment across the deck, new flashing at every wall and penetration, the shingle or membrane itself, and balanced attic ventilation to let heat and moisture out. Our certified installers build all of it, because a weak link anywhere is where Ottawa weather gets in.
Warranty and permits, handled
You get a manufacturer warranty on the materials and our written workmanship warranty on the install. For what a replacement costs by house size in Ottawa, see our roof replacement cost guide. When the job needs a City of Ottawa building permit, we pull it – so the work is done to code and on record.
Roof replacement FAQs
How much does it cost to replace a roof in Ottawa?
Most asphalt shingle replacements in Ottawa run about $4.50 to $7.50 per sq ft installed, so a typical home often falls between roughly $8,000 and $18,000 depending on size, pitch, shingle grade, tear-off, decking repairs, and ventilation. Flat-roof replacement costs more per square foot. Use the estimator on our services page for a ballpark, then book a free inspection for the exact number.
How many layers can be torn off?
We always tear off to the deck, however many layers are up there. Roofing over old shingles hides rot and shortens the new roof's life, so we do not do it.
Will you replace rotted wood under the shingles?
Yes. Once the old roof is off we inspect the decking and replace anything soft or rotted. We include a decking allowance in the quote and show you anything we swap out.
Do you offer a warranty?
Yes – a manufacturer material warranty on the shingles or membrane, plus our own written workmanship warranty on the installation.
