Insulating and venting | Ask The Experts Forum

Guest User 9/24/2012	I have a metal standing seam roof and I am having a problem with condensation. The roof rides up and meets an exterior wall with windows, see attached pictures. Originally I thought the windows where leaking until the sheet rock was remove to find the roof is not vented. The bays were paned and insulated properly however no venting exists where the roof meets the exterior wall. Is venting required for this type of application? What type of vent would you suggest that will not leak? Thanks,	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17826/find/

My email is [email protected] One option too is to spray the underside with closed cell urethane foam insulation.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17827/find/

Todd Miller Isaiah Industries, Inc. 9/24/2012	Thanks. That is very helpful. It would take some work by an experienced installer but it would be possible, if you can bring air in at the bottom, to have a vented topwall flashing that would exhaust air out. Ultimately that would help with overall building health and efficiency but spraying the underside of the roof deck with foam would likely be much easier.
