Gather the problem’s history
Note when symptoms appear and which areas have already been repaired. Invoices, photos or descriptions of previous work help establish whether the leak returns in the same place or involves several details.

The visible defect does not always define the whole repair. Nearby seams, flashing and deck condition may change the scope; the repair needs to remain compatible with the existing roof covering.
Ask which components will be repaired and which will remain. If defects are widespread, also compare replacement so you understand what each proposed solution actually addresses.
