I've got an existing building, roof slope 9.5/12 in which the existing rafters are toe nailed into the attic floor decking, and possibly the joist below (I haven't been in the space to verify, though I will ASAP). Due to loading changes I'm planning to sister the joists, and I wonder, anyone have a recommendation for a better connection to resist the outward thrust? There is no ridge beam or ridge board, the rafters simple meet directly at each other and I can't see any connection other than bearing. Any suggestions on how to connect these as well? I'm thinking some kind of light gauge clips/straps in both cases, I don't see anything specific in Simpson that will work. Since the slop is fairly steep, the kickout thrust shouldn't be too high.
Thanks for any assistance,
