Finding a Roof Leak in Shawnee
The place water appears indoors tells us where it reached the room. Before it gets there, rain can run along the roof deck or framing and drip farther down. A stain beside a chimney or light fixture is a useful starting point, but it does not prove that the roof opening is directly above it.
We follow the likely water path and examine the covering, flashing and penetrations around it. A plumbing vent has a collar and metal base; a wall joint has overlapping flashing; a valley carries water from adjoining slopes. Each detail has a different connection to restore when it fails.
Tell us the room, what you noticed and roughly when it started. If you already know that it followed a storm or earlier roof work, that helps too. Finding the entry point and deciding the repair belongs to the roofing work.
