Jerry Needham replied to Jerry Needham's discussion Condensation on ceiling and walls of master bedroom"Thanks for the reply Daniel. I have worked with several jobs where we did as you suggest and all seem to be good. I like the concept of the un-vented foam filled cathedral ceiling.

Jerry Needham replied to Jerry Needham's discussion Condensation on ceiling and walls of master bedroom"David
Not sure if there are any supply vents in the ceiling. I am scheduled for an energy audit on June 18th and will know a lot more about the house at that point. Just trying to get ahead of the curve prior to getting to the house."
Daniel Baur-McGuire replied to Jerry Needham's discussion CONDENSATION ON CEILING AND WALLS OF MASTER BR"Spray closed cell foam and get rid of soffit venting.
Problem fixed! Adding soffit vents just allowed hot moist air to hit, I assume, an underinsulated and non air sealed space. Doubt they actually vented the space with baffels all the way up the…"
David Butler replied to Jerry Needham's discussion CONDENSATION ON CEILING AND WALLS OF MASTER BR"Is it the cathedral ceiling that's sweating? Is the condensation on or adjacent to supply vents?"

Is this a flat/low slope roof? If its to the underside of the roof deck? You mention ventilation. How about the…"
Donald Hester replied to Jerry Needham's discussion Closed cell on roof deck to prevent mold."For the roof shingle issue that is an unfortunate issue with many home inspectors that have been given improper information.

Jerry Needham posted a discussionClosed cell on roof deck to prevent mold.
I am working with an insulation company who has already applied 2" of closed cell foam over the deck of a roof deck that has been remediated for mold twice. It was thought by spraying the foam, there would be no chance of the mold coming back. This is a million dollar home in the Chicagoland area and homeowner is trying to sell the home but a private home inspector says the foam will shorten the life of the roof and he has scared off perspective buyers with his talk.

Brad Cook commented on Jerry Needham's blog post Spray foam on attic deck to stop mold"molds needs oxygen, moisture, food and heat (above roughly 40 degF). The SPF will essentially remove O2.
