Toronto building services generally require a permit for any structural masonry, liner replacement, or new appliance install. Cleaning, cap replacement, and cosmetic work are permit-exempt. Turnaround for over-the-counter permits is usually 5–10 business days.
Certifications that carry weight
WETT SITE-Comprehensive, CSIA CCP or CCS, and WSIB clearance are the three signals adjusters and buyers accept without pushback. HRAI membership adds credibility on venting work.
Which rules apply
Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most roof cleaning work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.
Common questions
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.

Usually — call before 9am and we'll confirm a same-day arrival window inside Toronto for most standard scopes.
Is roof cleaning 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 need a permit for roof cleaning in Toronto?

2–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
