Roof Project Change Orders
Document and approve hidden-condition changes.
Use five lines on the Roof Project Change Orders decision sheet: condition that triggers a change; photo and location evidence; labor and material price effect; schedule and permit effect; written owner approval before work. Mark an unresolved Roof Project Change Orders line as an exclusion, allowance, or unanswered question instead of hiding it. Stay on the ground or in a safely accessible interior area. Roof access, destructive inspection, and installation belong with qualified people using proper protection.
Planning factors
Five decisions worth documenting
Use the headings as a proposal check. The actions beneath them are specific to this project decision.
Condition that triggers a change
Define which findings can trigger added work, such as unsuitable decking or an unrecorded interface. The trigger should be a documented condition, not a broad permission.
Photo and location evidence
Require location, photographs, quantity, and explanation before concealment. The owner needs enough information to understand why the original scope no longer applies.
Labor and material price effect
Separate labor, material, disposal, and related costs in the change. Ask whether the original allowance is credited or added to avoid double-counting.
Schedule and permit effect
Record effects on inspection, another trade, material availability, dry-in, and completion date. A price change can also alter the installation sequence.
Written owner approval before work
Name the authorized approver and communication method. Work beyond the agreed scope should follow the written approval process, with the revision kept beside the contract.

Before authorizing work
What record belongs with “condition that triggers a change” before work begins?
Request a dated description and the evidence supporting the proposed treatment. Cross-check entries: photo and location evidence; labor and material price effect. Named responsibility: schedule and permit effect. Closeout file: written owner approval before work. Identity check for Roof Project Change Orders: confirm the business, applicable County license, roofing insurance, and current Harrison permit steps separately.
