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.
Permit thresholds in Mississauga
Mississauga 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.
Common questions
Are you WETT and WSIB certified?
Yes — WETT SITE-Comprehensive #C-46082, CSIA #12408, and active WSIB #7248194. Certificates emailed on request before the job.
Do you offer same-day roof cleaning in Mississauga?
Usually — call before 9am and we'll confirm a same-day arrival window inside Mississauga for most standard scopes.
Is roof cleaning covered by home insurance in Mississauga?
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.
When's the best time of year for roof cleaning in Mississauga?
Late September through mid-November with Mississauga averaging 95cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
What warranty do you offer on roof cleaning in Mississauga?
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.
Do you need a permit for roof cleaning in Mississauga?
Cleaning and inspection are permit-exempt in Mississauga. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Do you service condos and heritage homes in Mississauga?
Yes. Condo boards in Mississauga typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
How long does roof cleaning take in Mississauga?
2–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
