Typically, this joint is flashed. Run the shingles up to the wall and flash behind the siding and over the top of the shingles.

What kind of siding do you have?

Well first off you should never install a lean to roof like that over vinyl siding. I would support that roof and remove the siding from behind and around that roof. If the structure can not be shifted against the wall then slip a strip or wood between the wall and plate of the roof structure and then use leg bolts to attach the roof structure to the studs of the wall. Once that is done you can then install the shingles all the way up and properly flash the wall to the roof as Spruce said. You can the install J channel around the roof structure and cut and re install the vinyl siding.
It really is not safe to have the vinyl siding pinched inbetween the wall and roof especially if you live anywhere that gets snow. Also if you do not have metal joist hangers on the roof joists connecting them to the joist plate then you really should.
I don’t mean to pick things apart but structures like this are dangerous if not done correctly.

hi ok thanks.. sorry what i did was cut the siding out around the 2 by 6. and fastened a 2 by 6 to wall. then i built the frame and screwed it to the 2 by 6 that was on the wall already i have 6 .. 6 by 6s holding the lean to roof up. one is not shown in picture. so its not really using the wall as too much support . if the water did leak it wouldn't be that big of a deal cause im gonna build a deck around the hot tub and some sort of privacy shutters or something between the 6 by 6..

so anyways i am trying to make the best of a situation that wasnt thought out very well lol

Ok so if you did not frame over the siding then you can remove the siding above roof and install the proper flashing easily once the shingles are fully installed and finished. I would also seal the shingle edge to the wall sheathing to add some extra security.
