Howdy all,
Rob Tom mentioned that metal roofing can be attached directly to purlins, thereby eliminating a lot of roof decking while giving you something to grab on your way off the roof. Sounds like a good idea to me.
So, what's the question? you may ask. (Or maybe you wouldn't...) My question is this: I have heard that the underside of the metal can attract condensation that might then drip down onto your ceiling insulation bales. (OK that's not really a question, it's a statement. Here's the question:) Has anyone experienced that type of problem? If so (or even if it seems a reasonable concern), any ideas on work-arounds? My brother the sometimes SB builder, bread baker, and aspiring masonry stove mason suggested tacking 30# roofing paper to the purlins, but he also acknowledged that that could make putting the metal up a bit more challenging. (Goodluck not stepping through the stuff. And goodbye hand, foot, leg, nose, etc. holds... )
Thoughts?
