I live in Minnesota, we have experienced a more frigid and snow filled year then a usual winter. My attic has developed frost on the wood. Its in all of the attic’s ceiling/loft.
I have a roofer coming in a couple days to look at it… I believe my soffits are in good working order, unblocked/that area appears to be dry. I think the insulation level is okay (had some blown in 3-4 years ago…
Is it possible a small vent such as microwave/kitchen exhaust fan could frost the entire attic? (size = lengths is about 50 feet, width is about 25, I believe makes 1250 square feet. Could one 6 inch pipe cause that much trouble, heat up the attic that much?
Or could I blame the new owens corning ridge vent that was installed with a new roof (this past summer)? A few weeks ago I went on my room to clean off some of the snow near the gutters, I noticed there was a fairly good level of snow and ice build up on and around my ridge vent. Is it possible for it to get iced over if its really cold (we have had a few -15 to -20 days/nights this winter?
Problem part 2, we just had a pair of 40-degree days… The ice is thawing, making water marks on my ceiling… I went up to dry off the wood by hand as much as possible to ward off further ceiling damage.
After the roofer finds a solution to the problem (add a new turbine or other vents, finds that its an exhaust pipe… what then? the wood is still a little damp… if there attic now gets proper ventilation, no extra heat, etc what will need to be done? Will the wood dry itself… do I need to find a way or someone to dry the wood in the attic?
Long post/question… sorry I have a big problem and I am looking for all the help I can get.
