Hi I had my roof done this summer. There has been pretty huge rain and quite a bit of snow this year and I haven't noticed any leaked yet. As of now, there's a lot of snow on top of my roof. Yesterday, I went into the attic to check on the insulation. I have notices parts of the deck are a little wet. Places where there are ventilation are fine and pretty dry. The only wet part is the inside of the top of the roof. Everywhere else are dry as far as I can tell. I am not sure if I convey adequately. There are some pictures: There's also this interesting situation where the roofing nail is covered with ice. My question is, is it normal? Should I call up my roofer?
