Condensation and what to look for? | Ask The Experts Forum

Guest User 12/11/2012	I recently bought my first home and it has a metal roof. Today I went up to the attic and noticed some dripping from condensation at the apex of the roof. There are two vents, one facing north the other south as that is where the wind tends to blow. There is fiber glass insulation laid down, though not a thorough job of it. My home is a berm home as well with the roof facing east and west slopes and the berm on the east side of the home. It feels like there is decent air flow but probably not enough. What do I need to do to fix this problem?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17957/find/
Todd Miller Isaiah Industries, Inc. 12/11/2012	How is the metal roof installed? Is it on top of decking (such as plywood) or is the bottom side of the roofing exposed? Generally condensation issues are controlled through a combination of ventilation, insulation, and a vapor barrier.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17958/find/
Guest User 3/11/2013	Todd, I have a similar problem with leaks from the ridge vent. We do have soffit vents and we do have Cobra installed. Still, the issue seems related to blowing snow and subsequent warm up. All of the water stain evidence is directly below the center, where the ridge vents run. This is the 7th year in our home in Central Indiana. Any suggestions on how to stop this?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17959/find/
Todd Miller Isaiah Industries, Inc. 3/11/2013	Steven, have you checked to make sure that air is flowing out the ridge vent and you're not sucking air in there? You can check with a smoke pen in the attic or even by holding up a light piece of tissue paper.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17960/find/
