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 flashing repair is disproportionate to the cost savings.
The Hamilton rental market angle
Landlord flashing repair DIY on rental units in Hamilton 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.
