I will soon be doing a roof for a friend in Illinois. It's a hybrid timberframe. The main body of the house is a 2- 1/2 story 10/12 pitch frame made with King post bents. My concern is the panels on the roof. They are made up of 1"tounge and groove spruce, 4-5" foam,and 1/2" plywood.
When my company stocks or puts bundles of shingles on roofs, we load the whole job at once. Normally on a steep roof such as this we use a 12' or 16' 2x4" nailed through to the rafters. Question, Seein as how I wont be able to nail through the panels in this case, I need to figure out a way to keep them up there. Lotta weight, those 2x's will just tear right off the roof.
Another question, same problem. When putting my hooks or brackets at the bottom will the panel hold my weight, plus a square of shingles? Yikes!
Once again, Normally I'd put the 16p nail in a rafter and feel safe, but I dont think 1/2" plywood will hold all that.
Any thought s or experience please write me, here or at JGYOGA@aol.com Thank you JG
