Roofing Change Orders: What to Record Before Approving Extra Work
Quick answer: When a roofer discovers additional damage, ask for a written explanation, supporting photographs when safe, the added scope, price and schedule effect before approving nonemergency extra work. Keep the change with the original contract so the final invoice can be reconciled.
What changed from the original scope?
A decking allowance can be exceeded after tear-off. A concealed flashing detail may require additional work. Ask the contractor to separate a newly discovered condition from work already included in the price. A verbal statement that “the whole thing is worse” is not a clear scope.
| Change-order item | What to request |
|---|---|
| Condition | Location, description and safe inspection photographs |
| Work | Quantity, materials and tasks being added or removed |
| Price | Unit prices, allowances used, credits and revised total |
| Timing | Impact on completion and temporary protection |
| Authorization | Dated approval through the agreed contract process |
Check the allowance before paying twice
Compare the original proposal's decking or repair allowance with the newly measured quantity. Ask how included amounts are credited. Keep the explanation specific enough that someone reading the file later can understand the calculation.
Discuss protection while the decision is made
An open roof may need prompt protective action. Agree on communication and emergency procedures in advance, and follow qualified safety advice. Do not climb onto the roof to verify a finding yourself.
Keep a final record
Retain the original contract, approved changes, inspection documentation and final invoice. CSLB's homeowner resources provide California contract and hiring guidance; local requirements differ outside California. A referral service does not approve a change order or guarantee workmanship.
