Start with documentation
Take photos of missing shingles, lifted shingles, damaged vents, interior stains, and any emergency mitigation. A written inspection helps separate visible damage from assumptions.
Understand the scope
A replacement scope should identify tear-off, decking, underlayment, flashing, vents, penetrations, ridge, cleanup, and warranty details. If insurance is involved, a clear scope reduces confusion.
Keep repair and replacement options separate
Some storm damage can be repaired. Widespread shingle failure, multiple leak paths, age, or repeated damage may make replacement the practical path.
