Hi,
I’ve been renovating an old outbuilding during which I removed a rotten roof and strengthened and secured walls and replaced corrugated iron gables with concrete block ends. It’s going to continue to be a shed.
I'm now ready to commence the roof construction which will be pretty-much a like for like replacement- but will be cut by hand and not trussed.
The internal wall dimension of the building is 8m x 2.8m. I plan on placing rafters at 0.8m intervals and these will be secured to a ridge-board and to 100x75mm wall plates. The main modification will be that I intend to add sarking boards, and then clad with corrugated iron roof sheets as before.
The pitch is about 40 degrees, (run of 138 with height of about (from memory) 120).
My questions are:
• is a rafter dimension of 50 x 100 sufficient (as before);
• is rafter interval of 80cm sufficient (as before)
• what nail size is most suitable for the wall plate end and at ridge end
I’ve not placed a wall plate across the gable ends as I’m not planning on adding a ridge stud support. Is this ok?
Thanks, and sorry if these questions make you cringe!!
