I have a pitch roof of 20deg and a span of 2.7m. I have used C24 150x50 for rafters and celling joists. (The roof runs down the existing house wall then a small ridge meets two hips.)
Do i need to put noggins between rafters and between joists? if so do they need to be 150x50? i obviously need to at the gable to attach the straps to.
Also do i need to diagonally brace under the rafters?
and do i need to somehow tie the rafter to the joist mid span?
Thanks
Ben
