VERT / GREEN
Map shedding zones after winter events and keep critical access out of fall paths.
Metal roof: sliding snow and ice
Assess where snow/ice can release from a smooth roof onto entrances, decks, heat pumps or travel paths.
JAUNE / YELLOW
Adding retention devices changes how snow remains on the roof and can affect local loads, attachments and roof warranty.
ROUGE / RED
Snow/ice shedding onto an exit, overload signs, deformation or retention device on large roof: roofer/engineer as appropriate.
Interactive triage
Helps choose the next step; it does not replace design, permits or professional diagnosis.
Useful tools and data
- Slope/entrance plan
- Post-storm photos
- Roof type/attachments
What the professional checks
- Assess snow load
- Verify attachments/retention
- Protect exits/equipment
