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 vent install is disproportionate to the cost savings.
The Oakville rental market angle
Landlord roof vent install DIY on rental units in Oakville voids most policies and shifts full liability to the owner under RTA §20. Not worth it.
