(I am a first time homeowner doing my first attic inspection.)

The prolonged cold weather in my area gave me a good opportunity to look for problems in my attic yesterday. The only thing I found that I was unsure about was some frost on the underside of the roof. It's not very heavy frost, and it is confined to the far edges of the attic.

Is this a cause for concern?

We need pictures or some heavy detail. What are the dimensions of the frost? – DMoore Feb 10 '14 at 19:43
And is there insulation below the frosted areas? And is there a vapor barrier anywhere? – bib Feb 10 '14 at 20:06
Having frost inside the attic is not good. It means water has penetrated below the roof. It may be due to faulty shingling or lack of a drip edge. It should be addressed to prevent rotting of the boards at the edge of the roof. – getterdun Feb 11 '14 at 0:44
@DMoore - Unfortunately, I didn't think to take photos, but there are a couple of patches maybe about 6ft x 4ft, although the rafters in that space do not have frost. – anon Feb 11 '14 at 14:34
@bib - There is insulation below that area, with the lowest layer having a vapor barrier that faces downward. – anon Feb 11 '14 at 14:37
