Reinforcing joists


I have an old unfinished 16' wide garage and trying to reinforce roof joists to then put plywood down and light storage. My problem is the joists rest on top of the garage framing, where the wall ends and the roof starts. Although I cut 2x4's at the same roof angle and length as the existing joists, because of the framing, I cannot maneuver the new joist past the framing to then nail to the old joist. Any help in figuring this out would be appreciated.

cut the ends a hair shorter, though not so far as both ends will not slip over the plate. slide in one end, pull from other end to fit on edge.

Reinforcing joists


DM,
I tried cutting the joists a little shorter, about an inch shorter, but I still can't get the new joist past the 4x4 that is the top of the wall frame. Should I just keep cutting until it fits. It appears I will have to keep cutting until only about an inch of the new joist will rest on top of the 4x4 (while the old joist extends all the way to meet the roof at an angle, more than 3 inches). With just one inch on the 4x4, will that still provide reinforcement?

Thanks,
Mull

you should think about support from underneath as well. your idea of 'light storage' may not be the same as the next owner who wants to store his bowling ball collection up there with the antique cannons.....

i don't see why one inch should be a problem. you're reinforcing what is already there, after all. another option could be cut them in half, then put them in and use a third 2x as a band-aid in the middle. lol

The old joists also have two boards (1x6s maybe?) nailed to the joist and the roof rafter, which I plan to repeat...unless you or someone else tells me this is a bad idea.

that would make for an ok loft then, IMHO. those supports will help a lot. but there's still that guy with his cannon collection.....

you should call the inspectors office to check if you need a permit for this as well.
