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.

Common questions
Do you need a permit for roof cleaning in Cambridge?
Cleaning and inspection are permit-exempt in Cambridge. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
When's the best time of year for roof cleaning in Cambridge?
Late September through mid-November with Cambridge averaging 109cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
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.
Do you offer same-day roof cleaning in Cambridge?
Usually — call before 9am and we'll confirm a same-day arrival window inside Cambridge for most standard scopes.

Do you service condos and heritage homes in Cambridge?
