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

What the professional checks

Roofer and, when needed, structural professional assess exposed substrate before it becomes inaccessible.
