I did a Thermal scan for this client, and when I got to her attic space I found there to be about 16"-20" of blown in insulation in places. She had it installed because she has a hard time keeping the 2nd floor cool in summer and warm in winter.
So the insulation installers came in and blew in gobs of insulation to try and help this. I noticed what looked like moisture on the roof rafters and decided to look at them with the TI. Hard to get a good shot because it was 120+ in the space and nowhere to go.
So, long story short, there is no venting in the attic, the roof is a gambrel style, there are vents at the bottom of the bottom roof, but with all the insulation that was blown in, if the soffit vents were working prior, they are not now. Even if they did, there is not place for it to exhaust.
Now my question, the moisture noted in the rafter, is this due to condensation because the insulation is packed in there, she said her roof is new (I don’t know how new) so I am assuming it is not leaking. If you notice, the one to the right is the same way, but not as severe.
Everybody’s thoughts are welcome.
