VERT / GREEN
Inspect snow, gutters, soffits and ice-dam signs before adding an electrical system.
Roof and gutter de-icing heat cables
Understand when heat cable is a supplemental measure and when it is masking insulation, air-leakage or ice-dam problems.
JAUNE / YELLOW
A cable can help locally, but it does not replace envelope correction or functional roof drainage.
ROUGE / RED
Improvised cable, permanent extension cord, damaged cord or water at a connection: do not use and have it corrected.
Interactive triage
This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.
Useful tools and data
- Roof/gutter plan
- Ice-dam history
- Cable/control data
What the professional checks
- Diagnose thermal cause
- Verify circuit/electrical protection
- Coordinate drainage and roof safety
