Metal building and condensation
I got a call from a friend Friday. He was asking me about a metal commercial building that was having a problem with condensation on the underside of the roof. He had not been out to see it yet so he did not have all the details.
From what I gathered it didnt have insulation against the underside of the roof. There was an insulated flat ceiling with an air gap above. Supposedly not much room in between.
Does a metal roof require the insulation in contact with it to prevent the condensation. Or if the air barrier is improved will venting do the trick.
Nearly forgot…..Climate zone 5a. We have had snow on the ground sine mid December, only a few days last week that melted a lot of snow but back to single digit lows.
