Common questions
Is roof repair covered by home insurance in Toronto?
Sudden damage (storm, animal, appliance failure) is usually covered minus deductible. Gradual wear generally isn't. A written pro assessment before the claim call materially improves outcomes.
Do you offer same-day roof repair in Toronto?
Usually — call before 9am and we'll confirm a same-day arrival window inside Toronto for most standard scopes.
Do you need a permit for roof repair in Toronto?
Cleaning and inspection are permit-exempt in Toronto. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
How long does roof repair take in Toronto?
2–5 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
What warranty do you offer on roof repair in Toronto?
Five-year written workmanship warranty on materials and labour, transferable to a new homeowner within that window. Manufacturer warranties on any installed products pass through separately.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
When's the best time of year for roof repair in Toronto?
Late September through mid-November with Toronto averaging 127cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
