I spent a long time trying to figure out how to put in joists without offsetting them. I finally bought some longer screws, which of course used Torx, and I Had been concerned with pre-drilling at an angle, with the slope of the ceiling.

Except I am not up against the ceiling, I am up against that pink cotton candy.

I cut and installed 2x4s against the front to support the corners of the new section.

I couldn't find my long Torx driver or my small extension. The screws wandered too much, at least on the 6" extension I found.

In some places I couldn't fit the extension, at least until I drove the screw as far as I could, so I pre-drilled, started with the bit, and then switched to the extension.

I put in a cleat to hold one end of the boards while I screwed in the other, cut, and installed the next set of boards.

I felt disappointed to only do one set.

It was raining and with all of the lumber that I have bought over the years, the wood I bought to make that lady a wheelchair ramp, and the wood I pulled out of the shed, which had supported some ugly shelves, I only have 2 2x4s left.

I need to cut another board like the one that I installed in the front, but it won't be long enough to reach studs besides the first one.

I could cut through the foam in the back, insert spacers, screw through the siding, and then screw the edges of the back joist to that.

That doesn't sound stable.

Neither does cutting through the fiberglass and trying to secure it to the roof, on top of needing to seal screws that I put through the roof.

Also, I loathe trying to screw through siding or the roof when I don't have x-ray vision.

I think that my best bet is to cut a narrower piece, screw it to the main one, and screw that to the back.

I don't know how to reduce flex more than that without cutting a 1.5" between the back studs, attach them to the studs, and then screw the new joist to that.
