Here's how Cambridge homeowners actually approach roof cleaning in 2026, based on what our field crews see every week. Suburban wind loads and freeze-thaw cycles drive most masonry failure. Below: what to expect, real numbers, and the questions worth asking before you book.

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 Cambridge

Common questions

Is roof cleaning covered by home insurance in Cambridge?

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.

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 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?

Yes. Condo boards in Cambridge 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 Cambridge?

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

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 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.

What warranty do you offer on roof cleaning in Cambridge?

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.
