but that’s for a different discussion) & for such a small project, I think I’ll go top end - but then there’s not really a whole lot to do on a simple gabled roof / no valley / 5:12 structure that’s less than 2 squares.
I was thinking Ã‚Â½" type OSB over rafters, Gorilla Guard, then maybe a layer of 4x8 foam board (the Ã‚Â¼" thick type) with purlins over this & a simple corrugated metal or 5V Crimp. Edging will probably be reversed C channel galv. metal over fascia (or not if I go with a wooden drip edge) & maybe even a 1-Ã‚Â½" drop drip edge (or a custom 3" galv. drip if no wooden drip) with the metal roof panels extended about 3" beyond the fascoa (eaves should be 18" deep & not back slanted or angled as I instructed the framer).
I’ll also add a ridge vent product to the center; one that’s metal specific. I’m also going to add eave vents on a fully cased in soffit & the walls are being built about 4’ taller than ‘normal’ height for lofting concerns… which essentially means I’m going to finish in a ceiling.
Now, I’m no metal guy :arrow: but I don’t think it will be any difficulty anywhere in there, however a friend who used to do framing said I will get too much expansion & contraction out of the insulating styro sheet. I will probably staple insulation under the deck as well, however that’s easily done after I finish the cap & siding work (going with Hardie lap, BTW).
:mrgreen: you should be happy with the metal & exposed screws, LoL. It will have electricity run to it & I intend to wire up for a window A/C when I find a decent unit on CraigsList or somesuch inexpensive unit (will frame a hole in the wall vs. an actual window). I’m putting an A/C in there because this is where we’ll be storing the saddles & some feed; it’s important to keep the humidity to a certain level - not too high, not too dry.
