Roof Replacement
A proper roof replacement is more than new shingles — it is a chance to inspect every square foot of your decking, upgrade your underlayment and ventilation, and install a system designed to outlast the next two decades of West Coast weather. Island Roofers performs complete tear-offs on Vancouver Island homes from Victoria to Campbell River.
A roof system, not just a product.
- Full tear-off down to the deck
- Plywood and rot repair priced transparently
- Upgraded synthetic underlayment and ice-and-water shield
- Most homes completed in 2 – 4 days
Why tear-off matters
Layering new shingles over old hides rotten sheathing, traps heat and voids most manufacturer warranties. A proper tear-off is the only way to guarantee a true 30 to 50 year roof.
Ventilation upgrades included
We bring intake and exhaust ventilation up to current best practice, which reduces ice damming, extends shingle life and lowers attic temperatures in summer.
How a roof replacement project actually runs.
- 1
Tear-off
We strip the roof down to the wood deck, exposing every nail, vent and flashing so nothing is hidden under new material.
- 2
Deck inspection & repair
Rotten or soft sheathing is replaced at our published per-sheet rate — you see what we replaced and exactly what you paid for.
- 3
Underlayment & flashing
Ice-and-water shield at eaves, valleys and every penetration, synthetic underlayment across the field, and new pre-finished flashings throughout.
- 4
New roof system
Shingles, metal panels or membrane installed strictly to manufacturer spec with starter, ridge and ventilation from the same system.

Roof Replacement questions, answered.
How do I know if I need a full roof replacement?+
Signs include curling or cupping shingles, granules accumulating in gutters, daylight visible in the attic, repeated leaks, or a roof past 20 – 25 years old. A free inspection from Island Roofers will give you a clear answer with photos.
Should I layover or tear off?+
We never layover. Layering hides rotten decking, voids most manufacturer warranties, and shortens the life of the new roof. A full tear-off is the only way to install a roof you can warranty for 30+ years.
What is the average cost of a roof replacement on Vancouver Island?+
For an average Island home in 2026, a complete tear-off and re-roof with architectural asphalt runs roughly $9,000 – $22,000. Standing seam metal runs $25,000 – $55,000. Final price depends on size, pitch, access and deck condition.
Will rain delay my roof replacement?+
We never leave a roof open overnight. Sections are torn off, dried in and finished the same day, and we monitor Environment Canada forecasts daily so your home is never exposed in a downpour.
Do you offer financing for roof replacement?+
Yes — we partner with Canadian lenders to offer 0% promotional and low monthly-payment financing for qualified homeowners. See our Financing page for current options.
