Roof past 15 years
Most GTA asphalt roofs start failing between 15 and 25 years. Past that point, patching buys a season at a time.

What we see most
Signs a roof is ready for replacement
These are the conditions that usually move a roof from patching to planned replacement.
Repeat leaks in different areas
One leak is a repair. Leaks appearing in new places each season mean the roof system itself has run out.
Get a replacement quoteWidespread shingle failure & granule loss
Curling, cupping and lifted tabs across multiple slopes mean the seal strips are gone system-wide. Granules washing into the gutters confirm the mat is exposed and the shingles are near end of life.
Get a full-system assessmentFailing flat / commercial membrane
Ponding, seam separation and blistering across a low-slope roof call for a full membrane replacement, not patching.
Ask about commercial systemsSoft or damaged decking
Spongy sheathing and sagging lines between rafters can only be corrected with a tear-off and re-deck.
Book a deck assessmentRoofing systems
Roofing systems we install
A roof is a system, not just shingles. Every quote states the exact components being installed.
Architectural asphalt shingles
The default for most GTA pitched roofs. Layered profile, good wind performance, wide colour range.
Metal roofing
Standing seam and metal panel systems for long service life and shedding snow.
Modified bitumen (flat roofs)
Torch-applied or self-adhered membrane for low-slope sections, additions and garages.
Underlayment, ice & water and ventilation
Eave protection, synthetic underlayment, intake vents and exhaust are specified with every roof system.
