Common questions

Is roof cleaning covered by home insurance in Hamilton?

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 Hamilton?

Usually — call before 9am and we'll confirm a same-day arrival window inside Hamilton for most standard scopes.

What warranty do you offer on roof cleaning in Hamilton?

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 Hamilton?

Cleaning and inspection are permit-exempt in Hamilton. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.

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 service condos and heritage homes in Hamilton?

Yes. Condo boards in Hamilton 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 Hamilton?

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

When's the best time of year for roof cleaning in Hamilton?

Late September through mid-November with Hamilton averaging 117cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
