The Toronto rental market angle
Landlord ice dam prevention DIY on rental units in Toronto 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 ice dam prevention is disproportionate to the cost savings.
Common questions
Do you need a permit for ice dam prevention in Toronto?
Cleaning and inspection are permit-exempt in Toronto. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Do you service condos and heritage homes in Toronto?
Yes. Condo boards in Toronto typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Do you offer same-day ice dam prevention in Toronto?
Usually — call before 9am and we'll confirm a same-day arrival window inside Toronto for most standard scopes.
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.
