Getting good instructions on installation | Ask The Experts Forum

Guest User 7/11/2005	I am in the process of rebuilding an 1870's barn that I dismantled ( numbered all beams, posts, joists and sheathing boards) and am stuck on finding a good installation instruction set. I planned to use 2x4 purlins and attach directly to them. Ridge vent is screwed through the panels to the first level of purlins. Sound OK?

Todd Miller Isaiah Industries, Inc. 7/12/2005	This is reasonable provided the following: I would have a vapor barrier on the house side of any insulation. Make sure that a vented airgap is maintained between insulation and the roofing, with soffit intake and ridge exhaust. Make certain (100%) that the roofing manufacturer is agreeable to an installation on lathe boards of this nature for a residential roof. (Obtaining this may not be easy.)
