Roof Repair Starts at the Water Entry
The ceiling stain shows where water reached the room. The entry can be farther upslope at a flashing joint, a vent or damaged shingles, with water travelling along the underlayment or deck before it drops inside. Repair begins with that path, not with covering the spot directly above the stain.
We check the damaged area and the adjoining roof to see whether a local repair can connect to sound material. A split boot around a pipe is different from a roof-to-wall connection that has separated, and each needs the detail restored in the direction water flows.
