So we had our roof replaced in 2007 from a ribbed metal roof to a comp roof. We also live in Washington State in a gambrel roofed home with no duct work and about a 4' by 12' attic.
During the tear off, the metal roofing and stringers were torn off. Then sheathing was layed down, followed by paper, ice dam and shingles. Beautiful roof right!
Fast forward six months later, I was fetching something out of our small attic and there was standing water and mold under the visqueen. It was horrid and I was less than thrilled. So I called the roofer and he sent a dude out and he yoked out the bad stuff, painted the entire attic with Kilz and replaced the insulation, A few weeks later a few of them came out and cut in a ridge vent. Cakes and rainbows right?
Now, there are dark areas showing up on the ceiling where the rafters are. The only thing I can think of is that the rafters are getting wet.
So my question is what are the chances that the rest of the insulation is in as bad of shape as what I saw in the attic? Am i looking at a huge mold problem?
Also, before the sheathing was put down, shouldn't the stringers have been replaced as well? Without the stringers, wouldn't it be a giant dead space with no circulation? Looking from the inside, the layers are drywall, visqueen, insulation, sheathing and roofing. I would assume there is no air circulation.
There are a few roof vents but I'm not sure how effective those are either.
Any suggestions? Should I call him up after six years? Is this an insurance thing? Should I track down a mold inspector?
Any help or guidance would be greatly appreciated.
