Hail: roof and envelope impact assessment

After significant hail, document roof, skylights, siding and drainage without climbing onto a potentially damaged roof.

VERT / GREEN = documenter/entretenir · JAUNE / YELLOW = mesurer/vérifier · ROUGE / RED = arrêter et faire sécuriser/valider.

Broken glass/opening exposed
Secure the area and weather-protect it without unsafe exposure. Slippery roof or unknown damage
Do not climb; use ground/professional inspection. Dents/marks without visible leak
Document and distinguish true damage, wear and cosmetic marks. Post-storm record complete
Keep dated photos and affected components for maintenance/insurance.

What the professional checks

Inspect roofing, flashings, skylights and siding
Distinguish impact, wear and repair need
