Common attic water sources here
- AC condensate drain lines and secondary drain pans overflowing during the long cooling season
- Tank water heaters in the attic reaching the end of their life
- Roof leaks after hail, wind or worn flashing around vents and chimneys
- Supply-line fittings and PEX connections in the attic that drip onto insulation
- Condensation on ducts when attic ventilation is poor
Signs to check
- A brown or yellow stain on a ceiling, often under the HVAC closet or water heater
- Damp, compressed or moldy insulation when you look with a flashlight
- The smell of wet paper or musty air from a ceiling vent
- A full secondary drain pan under the air handler
- Higher humidity or a musty smell in upstairs rooms
Why insulation matters
Wet blown-in or batts hold water against the drywall and can grow mold. Soaked insulation is usually removed, the deck and joists are dried, and new insulation goes back once moisture readings are normal. Leaving wet insulation in place is a common reason a ceiling stain comes back.
Roof vs. plumbing vs. AC
A roof leak often shows up after rain. An AC condensate problem shows up on hot days when the unit runs hard. A water heater or supply leak can happen any time. Finding the source first keeps you from drying the wrong spot. See also AC drain leaks, water heater & AC leaks and storm & roof leaks.
Safety notes
Attics get extremely hot in San Antonio summers. Watch for exposed wiring, low headroom and soft decking. If water is near the air handler electrical disconnect, stay out and call for help.

Can wet attic insulation be dried in place?
Light surface dampness sometimes can. Insulation that is soaked, compressed or growing mold is usually removed and replaced after the deck dries.
Is an attic AC leak covered by insurance?
Sudden overflow from a clogged drain line is often treated as accidental water damage. Gradual leaks may not be. Check your policy.
Should I run the AC while the attic is wet?
Only if the drain is working and the unit is safe. A clogged drain will keep overflowing. A technician or restoration company can advise.
Can I call at night or on a weekend?
