Very timely thread for me guys, as I'm planning to reroof the shop here at my new place in the panhandle. So I really appreciate the info and experiences shared here.
The building is currently done with open 2x6 rafters with metal sheeting fastend on top. This leaks at many of the fasteners and at some of the seams.
This will be the first step of a major overhaul of the shed built structure. To include refastening the ply siding and cladding with metal sheeting. New garage doors, adding some windows, and a sliding glass door, etc.
As it is pretty shed built structure that Im wanting to convert to a more liveable man cave adjunct to my motorhome, which I plan to park under a carport built off the left side of the building.
So the reroof calls for some insulation to make it more useable in the summer heat.
Like Baz, I've come around to considering standing seam galvalum metal.
Any thoughts as to what materials, sequencing, and specs would be best and most affordable to archive the best results would be helpful, thanks.
My current thinking is 2x10" rafters, 5/8 ply sheathing, 3/4" or 1" foam, some sort of membrane, standing seam metal roofing.
The rafters span 21' from the end walls over a center beam. The 2x6 are pretty undersized even to support just the pearlings and metal roofing .
Cheers Richard
