The St. Catharines rental market angle
Landlord roof cleaning DIY on rental units in St. Catharines voids most policies and shifts full liability to the owner under RTA §20. Not worth it.
What you can safely DIY
Visual inspection with a flashlight, exterior debris clearing from the cap area (from a stable ladder, not the roof), and photo-documentation of concerns. That's the safe list.
What needs a pro
Anything requiring roof access, working chemicals or sealants, disturbing masonry, disassembling the appliance, or interpreting a scan. The insurance and liability exposure on DIY roof cleaning is disproportionate to the cost savings.
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 service condos and heritage homes in St. Catharines?

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.
How much does roof cleaning cost in St. Catharines?

2–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
Is roof cleaning covered by home insurance in St. Catharines?
