Roof deck after tear-off: inspect before membrane

Use the tear-off window to identify moisture, rot, delamination, fastening and geometry before covering the deck.

VERT / GREEN

Deck is visible, dry and documented before underlayment.

JAUNE / YELLOW

A covered defect disappears from view, not from the system.

ROUGE / RED

Deteriorated wood, questionable framing or persistent moisture: correct cause/substrate before new roofing.

Checkpoint before proceeding

Dark/soft/delaminated wood
Evaluate/replace and find source before covering. Opening/penetration changed
Review support, flashing and details before membrane. Deck wet after rain
Dry and verify condition before underlayment. Complete photos before covering
Archive with roofing warranty/work record.

What the professional checks
