I have a house with brick facade, so I neither can nor want to screw a ledger board into the brick. One option is to find studs behind the brick, but since there is an air gap in between, I'm not comfortable doing that myself, so I want to find another solution.
I have trusses on CC 120 and I'm considering two options and a third that I prefer to avoid.
1. Joist hangers in the fascia board (which is nailed to the trusses) and placing the patio roof trusses in them.
2. Remove the fascia board and replace it with a beam (120x45?) that is screwed into the trusses, then joist hangers in that?
3. Hang the patio roof trusses under the house's trusses, attached with nail plates. I've seen this option on other houses here on the forum, but I prefer not to use CC 120 because then I would have to significantly increase the size of the patio roof trusses, plus they won't be exactly where I want them, and I'd have less slope on the roof.
Has anyone done something similar or can offer tips?

I realized that I read another thread earlier where a bearer was attached to the ends of the rafters and a 45x45 timber was glued and screwed on the underside for the patio roof rafters to rest on, sounded like a convenient solution but then I have to increase the size of the bearer, but that's okay.
But with what screws do you attach it to the ends of the rafters?

Before we renovated and remodeled the deck, the existing deck roof was attached with 45x120 beams that were fastened "on the side" of each rafter, almost like option 3 but next to instead of below. Across them were 45x45 beams. At the front edge, there was a 45x170 support beam on posts that the 120 beams rested on.
It had quite a steep slope for a deck roof, was only 2.2 meters deep and 15 meters wide.

Went out and looked a bit more now and it will probably be too tight to screw towards the ends unfortunately, was misled by the fact that the footboard is a bit higher so it looks like there's more to screw into. So it will probably have to be option 3 or, as you say, laying them next to each other and screwing parallel. Or do you have any other tips since your renovation, if you found a better solution?
