A lifted shingle can expose vulnerable areas or indicate a fastening, sealing, or damage issue. Pressing it flat does not establish that the surrounding assembly is sound. The cause and condition of adjoining shingles matter.
What to do next
Ask whether the repair can be completed without damaging neighboring material. Request the proposed method and compatible replacement product. If several areas are affected, have their locations documented before deciding whether a local repair is sufficient.
