Blown in attic insulation blown away...
I need your help on this one please:
This morning I noticed a water spot on the ceiling of my master bedroom. There was no rain in the last few days here in Scarborough. I went up in the attic and sure enough I found some spots that were bare; I could look right at the drywall of the ceiling below. There was condense under the plastic barrier which led to that water infiltrating down.
This is a new house and I'll contact the builder tomorrow morning. I assume (hope) they will come and fix it. What I'd like to know is why this happened in the first place and how to avoid it in the future?
I also took several measurements of the thickness of the insulation in unaffected spots: it read 10". Is this according to the Building Code?
