After putting it off for way too long with quite a few leaks, I had my roof redone in the beggining of Aug. Tore off the old asphalt shingles completely, had the roofer put down a layer of 1/2″ ply over the planks since there were gaps of 1/2″ or greater, 30lb felt and some decent architectural shingles. The roofer came came well recommened.
I was up in the attic recently after some heavy rains (mid Dec) and the framing in the places where there were leaks before seemed wet, above 30% moisture content according to my moisture meter. I had the roofer back, he took the shingles off in that area and the tarpaper showed no sign of water.
The framing dates back to 1892, could it still be holding that level of moisture from before Aug when the leaks were happening? I would have thought it would have dried out by now since there were quite a few hot days since the roof was redone and it is like a kiln up there in the hot weather.
Another thought I had was maybe these areas that were subjected to water from the leaks is more prone to airborne moisture coming up from the house? I’m skeptical that moisture from the living area is condensing on the rafters since it is only in certain places and the soffits are actually open right now so venting shouldn’t be an issue though I didn’t have the ridge vented.
Anyone run across something like this? I don’t want to beat this guy up if it isn’t his fault.
