sistering rafters

Binglj · 21 Jul 2005

Hi,
My new trussed rafter roof will join onto my existing purlin roof at 90 degrees i.e. on one slope. Will I need to sister/double up on every rafter or just in the areas where the reducing trusses will bear??
Any help on coach bolt diameters and spacings would help as well.
Cheers,
John.

I'm not sure if I'm reading this right, a photo would help.

Normally I use a 6"x1" flat across the trusses to the correct angle and fix the new single truss timber to the board.
