Vetting a Oakville contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Oakville references from the last 12 months you can call — not read.
Red flags on quotes
Verbal-only pricing, deposits above 20%, cash-only discounts, and unwillingness to itemise materials by brand are the top four. Any one is a pass.
What a defensible quote looks like
Written scope with photos, itemised labour + materials, 30-day validity, WSIB and liability certificate attached, and named workmanship warranty (5 years is the current bar for roof cleaning).
Common questions
Is roof cleaning covered by home insurance in Oakville?
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 cleaning in Oakville?
Usually — call before 9am and we'll confirm a same-day arrival window inside Oakville for most standard scopes.
When's the best time of year for roof cleaning in Oakville?
Late September through mid-November with Oakville averaging 119cm 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 Oakville?
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 Oakville?
Cleaning and inspection are permit-exempt in Oakville. 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 cleaning take in Oakville?
2–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
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.
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.
