Will the repaired area match?
New shingles can differ in color from aged, weathered material. Identify the product and likely visible boundary before work so the appearance is part of the decision.
When can the repair uncover more work?
Underlayment or decking may be hidden until shingles are removed. GAF explains that decking may be replaced as needed before new underlayment and shingles; document and approve that added scope before covering it.
What should a replacement recommendation explain?
It should identify which roof areas and observed conditions support wider work, along with removal, decking decisions, underlayment, and cleanup. Compare it with the defined local repair scope.
