A ceiling stain is only the part of a leak that reached the surface. Above it, insulation and drywall may be holding water that the stain does not show, and the source can be a roof opening, a supply pipe, a bathroom above or a drain.
Reading a ceiling stain
- A brown ring that grows after rain points to the roof
- A stain that stays the same size points to a pipe
- A bubble or sag means the drywall is holding water
- A drip from a light fixture needs the power turned off
- A musty smell without a stain can mean a wet cavity
Brown stain spreading overhead? The crew can open the ceiling and dry it at any hour.
Ask about the wet ceilingSummer rain adds to the risk
June through September bring between 6.65 and 7.79 inches of rain a month here, so a roof leak that was quiet in winter can show up as a stain in the wet season. A pipe leak does not depend on the weather, which helps tell the two apart.
What gets opened
A small hole lets the crew look at the insulation and the back of the drywall. Wet insulation is removed, firm drywall may be dried in place, and a sagging panel is cut out before it falls. Roof causes continue on the roof leak water damage page.
For a stain beneath an air conditioner, see AC condensate leaks. The Zephyrhills water damage page lists the other local services.
