What tryp ridge did they install?
Askeyb: I am not sure. It was the third ridge cap venting. It has a scotch pad looking black material. Roofing was installed over it.
If it's Cobra vent then that's part of your problum.
How far did they open up the roof at the peak?
askeyb: I think a couple inches on each side.
A ridge vent is useless if you also have gable vents or any other type venting.
askeyb: The roofer today told me they should of never installed ridge cap venting with the fans already installed on the roof. The contractor that did the roof even had me buy humidity thermostats for the fans so I would be protected against heat or moisture. The fans never came on till recently and last week ran for almost 24 hours and again today for about 10 minutes.
Those power vents should have been removed when the ridge went on.
All those power vents are just drawing in air from the ridge vents not from the soffits.
It would be nice to see a picture of the soffit vents you have now.
The attic should have been air sealed any place there's ceiling lights, or fans, any place wiring or plumbing was run through the top plates.
There should have been baffles to keep the soffit vents clear of insulation.
askeyb: one of the previous owners had insulation blown into the attic and they didn't put card board barriers in to block insulation from covering the eve vents or suffits. My wife and I went around the house blowing out the suffits. The one area I had to go into the attic and remove wood that had been placed over the suffits. Interesting is that the original roof did not have a moisture problem even with what was found. The contractor blamed the problem in 2008 to the suffits and suffits that had been covered. The contractor had holes drilled and round vents installed for more ventilation. I was told that those little round vents are worthless.
Another issue I was told is wrong is a mushroom vent was used on the roof for the bath room vent. The vent hose is wired to the struts and pointed into the vent. Contractor told me that a round vent that the hose clamps to should of been installed.
Sure you have enough insulation up there?
askeyb: I believe I do have enough insulation but more would probably be better. The current blown in installation is as deep and a little over the framing on the bottom of the attic. You can still see where to place your foot when in the attic and it looks pretty deep. I would describe the material as looking like worm bedding.
Attached is a picture I took today. You can see the ridge cap venting material, black at top. You can see the mold in the plywood. And the sky lite with nothing around it. The vent to the bath room is barely visible but you can see the open vent on the left side of the picture.
