Howdy -

I put a wood stove in last winter and despite all the hurdles and fears of leaking roof, etc..all seemed to have gone well through the first winter. I have been up in the attic several times to check out the situation during hard rains, etc. and have never seen any issues.

Last week we had a heavy wet snow in the upper 30s and then right after it got down into the lower 20s and we've stayed at that. I had a small roof leak from a nail popping up and went on the roof to fix it. While up there I went to give the chimney pipe a once over just to monitor the condition. I suspected non-water tight bead around the storm collar. I went up in the attic to check it out and sure enough a few drops had made it through.

While in the attic I noticed that the plywood all around the chimney pipe is soaking wet and condensation drops could be seen on roofing nails etc. even have some mold starting...so I think it is something that has been happening even since last winter, but perhaps I never went up during colder weather to check it out. I've identified some issues with ventilation on the eaves/soffit areas in the attic and am going to do some retrofitting to improve that. Things that should be done regardless.

While sealing off the storm collar I noticed the shingles around the stove were soaking wet at as well now, which I did not notice the day before when I identified the problem, the rest of the roof is dry. From what I can tell there is no water actually leaking in under the flashing. Perhaps the shingles were still wet from ice melting, not sure...but don't think so since the rest of the roof is dry.

Has anyone else had this problem? I fear that the stove pipe is leaking a lot of heat into the attic and creating the condition. The insulated pipe stays fairly cool even when I have the stove very hot, so I think maybe need to reinforce the attic insulation shield with some more screws and a bead of silicone around where it meets the pipe and on the framing for the ceiling support, none of that is mentioned in the installation instructions though.

Will put some pictures up if necessary, but looking to hear from anyone who has had these issues and worked through it or just may have some insight into the situation. My wood stove saves me a lot as I have unlimited access to great firewood and don't want to settle for using the propane furnace which is terribly expensive, especially after spending the money and time to get it in operation.

Thanks a bunch!
