Separate plumbing water from roof water
A bathroom above may point toward a toilet seal, shower assembly, drain or supply connection. Staining that appears during rain calls for inspection of roof openings and the insulation beneath them. The crew considers source repair findings, moisture pattern and water appearance before assigning category and selecting cleaning controls.
Readings extend from the stain through nearby ceiling finish and wall tops. An attic or upper room is inspected where accessible. Insulation can hold water away from the visible center, so the edge is marked before any selective opening changes conditions.
