Hello, First timer here, Single story with small attic 12/3 pitch metal roof w/2 layers of shingle underneath. I have a few areas where the decking (seen in attic) is damp to very damp. It looks like rain/snow/ice is getting in at the roof cap. I can see the wet wood right at the ridgeline and seems to work its way through the decking or between the layers of shingle underneath? Maybe? Also have seen these areas DRY in some summer months. I need a new roof but cant until next year & would like to stop this moisture infiltration asap. I have Gable Vents/no ridge venting. What are my options? Foam-Fill in a can? Remove the cap and seal up the open areas? This install was done years ago (incorrectly) way before I bought. Thanks yall

Charles, is there any chance you can send me photos showing the outside of the roof? What you describe could be a leak but it also sounds a bit like condensation. What is the ventilation like in the attic? Just gable vents and no other vents? No soffit vents? Has anything else been done to the house recently to make it "tighter" such as new windows or doors, house wrap and siding? My email is [email protected]

I can send some photos later today, and thanks for replying so quickly! Gable & soffit type ventilation. Nothing substantial has been done to make the house any tighter though. I know the metal does NOT have the joint-tape between overlapping sections and I actually had to install more screws right after I bought to keep the overlapped edges secured. I hope this roofer has another job somewhere else, like a 7-11 or video store. He did several crap-jobs on my street for storm damage, way before I bought though. I can see in a few places (attic) the start point of the wet decking right at the ridge cap then the moisture works its way downward toward the soffit.
