hello
My house was built in 2001, it is a two story colonial the roof has arcuteture shingles on it. My attic has at least 12 inches of blown in insulation in it, 6 inches of fiberglass blown in and 6inches of cellulose on top of that. My attic is being vented by soffit vents(with the pink P vents that run up along the roof from the roof line), two 18 x 24 Gable end vents and a ridge vent running across the top of the roof. All of these vents are open, the ridge vent and the gable vents are new installs.
The humidity in the house has been between 35 and 40%. However the humidity in the attic has been 65 to as high as 98%. The tempature in the attic is the same as the tempature outside, within 5 degrees or so. I don't think I have much heat lose from the house because the snow doesn't melt quickly.
Yesterday the tempature reached 50 degrees here in New hampshire and it was raining. The snow covered roof was melting and I went up in the attic and noticed that the sheathing had become very wet and droplets had form on the nails. This is not the first time.
I am at the end, I have had restoration guys and insulation guys here, trying to fix the problem. The restoration guys had me spend $1700 on the gable vents, the ridge vent and to re-route the bathroom exhuaust fan from in the soffit to out the gable end wall. The insulation guy states that there is no problem with the insulation (thought maybe the blown in stuff was holding in the moisture creating condensation). Today the restoration guys are coming to check to see it there is water under the shingles on top of the sheathing from the outside.
If anyone knows of anything I can do, I am very frustrated and I am scheduled to deploy to Iraq soon and don't want to leave this for my wife to worry about. Here are some pictures of the roof and the attic.
thank you
Michael
