The white you see is frost on the nails and plywood.....the sheathing is soaked and you can see that by the darker areas on the sheathing.
Also on this part of the roof there is maybe 1/8" of snow on top of the shingles.
You can also see in this picture above that the moisture has a definite ending point.

This pic above is a closer look of the first pic.

You can see here the water drop on the end of the nail and how wet the sheathing is.

Sorry about the angle of above pic, but this is the flat part of the roof (left angle side of the pic). The sheathing here is wet in areas (large areas) but not the nail heads here. And it is not exactly next to the area of the sloped roof that has the moisture problem.
By the way, There were two different roofing contractors on this roof. One did the entire roof 4 years ago and then a different one on the flat area this past summer.
My question here is, can the problem on the pitched roof be only condensation (the roofer is suggesting that about the water dripping off the nails) The Ventilation in the attic is not enough. I was quite comfortable in there and it was 8 degrees outside. Or do you think it is more of a problem with the installation.?.?
I could not see the top of the shingles because of the snow. So I don't know if the nail heads were exposed or not.
Thanks in advance on any opinions, The roofing contractor is going there tomorrow morning. ![icon_confused.gif](upload://qv5zppiN69qCk2Y6JzaFYhrff8S.gif)
