it is through out the place on exterior wall ceilings i would say the new roof is like 10 years old myself my wife and i have only lived here for two years this problem could have been going on for a long time

Provided I get the humidity reading and it is high, how do I get it down? My wife and I don't think it seems humid in here. I know I'm not an expert but I think the problem is that there is no air circulation in the old roof. Also we borrowed a dehumidifier and it was not getting any water in it.

they are gable vents
there was vapour barrier
i had a contractor here today and he said that he thinks i should get a turbine what do you think

i just went out and checked i do have soffit panels

I don't know exacty how the new roof was built I bought the place with it already on

The new pitched roof has a large vent at either face of the peak do you think its possible I need a vent at either end to circulate the air between the old tin roof and the ceiling to eliminate the condansation

I have a 12/54 1974 mobile home with new vinyl window vinyl siding a pitched roof. The pitch roof was put over top of the old roof which was a tin roof .Recently I discovered I have soft spots in the ceiling along the exterior walls i pulled down one of the ceiling panels and cut open the vapour bar...
