SB: Re: re: metal roofing

["Peter Sobey" <p.sobey@computer.org>]

Nick,

 

Here down under we use sarking between the iron roof and the purlins. It is blue on the upper side which is moisture absorbant, and foil silver on the underside which help a bit as insulation.

 

Cheers,

 

Peter

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?
