Roof & Insulation - 08/05/06 03:20 AM
I am re-roofing 200 +/- yr old TF 1-3/4 sty ell of my house. Total roof area is 400 sf, 5/12 pitch, has 3 bents, (end, midway & one against main house)& horiz. purlins 32" oc.
Plan to cover framing with 5/4 t&g or splined white pine, inside planed and beaded for ceiling. Then rigid foam, "tuff-r" two 2" layers, removing vapor barrier in middle and staggering & taping joints. Then 5/8 exterior ply wood covered with ice & water shield. This will be covered with "cedar breather" mat and white cedar shingles with ridge vent.
I have no experience doing this. Will the foam support a snow load? The foam comes with vapor barriers on both sides, is this the way to go? Would greatly appreciate any advice on methods and or products. Thank you
