Condensation

[Karen Johnson]

Will a rubber roof eliminate a condensation problem? Water pours out of my ceilings and down my walls when it is cold out. It is not from snow or from rain. There are no leaks. The colder it is out and the warmer inside water just pours out of ceilings and the windows sweat. Now all new textured ceilings are ruined and sagging down. All new painted walls are water stained. Any suggestions would be deeply appreciated. Thank you.

Karen, also try your post at www.mobilehomerepair.com in the forum section. I've seen this on my old storm windows, but not at the ceiling.

Karen,

Water in the light fixture indicates a negative pressure within the home. This also causes all the other condensation problems you have described.. I have seen many!
Two major causes of negative pressure within the home are1) Duct leakage... make sure all duct are tight, have them tested to know for sure. 2) Lack of return air pathways from bedrooms to the main body of the home... again can be tested and corrected....
I bet you keep your thermostat around the 70 degree mark or below.. this can be an indication of an underperforming a/c system. This does not cause a condensation problem, but can take a present problem and exagerate it. Find a respected a/c company to test how well your a/c is balancing it's heat and humidity removal.

I'm wondering if the walls and ceiling have a moisture barrier. Normally the air inside a home is more moist than the air outside. If walls do not have a moisture barrier, then the moist air from the living area travels through the walls to the cold outer walls and then condensation occurs. Sounds like the existing sagging ceiling panels need to be removed and replaced, but before they are replaced, a moisture barrier (normally just a thin sheet of plastic) needs to be installed.
