Hi,
I am totally new to this but recently got some experience with roofing with my DIY shed I completed (ground-up build). It was a sucess...!. My next project is a patio roof (shingles) over my deck. Dimensions are 14.5' x 12'. If this is a rectangular roof, it would have been simple as my shed roof but unfortunately, it's not. My construction includes 2x6 rafts and 4x4 poles.

This is a cartoon of roof (not to scale) - Image link added


My question is related to the left corner where it is angled (not rectangular) Since I don't have a pole supporting the middle raft of the three rafts on to the left, I am thinking creative way to have the best support to the middle raft without adding additional pole there.

This is the 3D sketch of it - Image link added


I am thinking of adding a cross-bar between first and third raft (in addition to edge) I will do a cut-out of 2.75" on both where they cross so that height remains at 5.5". Is there any other better way? I do not want to have any safety concerns here.

Thank you.

No, I am not using any cross trusses. What do you think about my cross-support between the leftmost and third raft?

What you drew here is the ideal case but my poles are not at the same height thus that beam is at an upward angle. Isn't that looking weird from the inside ?

It is a problem I have not seen before, It will look odd no matter what you do.
Is there a reason why you can't go out square?

Hi Nealtw,
My roof length is about 20 ft. So for the horizontal beam, if I use 4x6 lumber, would it be ok to have 3 4x4 posts ? I want to make sure it does not sag the beam with roof weight. I want 7.5' gap between posts with 2.5 ft overhang from both sides from last post. Or should I go with 4 posts? Do I have to have 4x6 for posts as well ?
My contractor says 4x4 is enough for the horizontal beam as well which I dought.

Where I live all decks and deck roofs get 6x6 posts and 2 ply 2x10 beams unless some one thinks they need more. So anything less than that would just be guessing from me. Depending on load and support from below our post might be 10 ft apart.

I did some progress with the plan. I decided to use a rectangular frame at the corner I was concerned. Going rectangle saves whole lot of trouble. This is my plan. I will build the frame and roofer will help with roofing.
One of the contractors I contacted said going 4"x6" is an over kill but I decided to use 4"x6".
Any feedback?

Thank you for your thoughtful feedback. I think I will move forward with this. I feel comfortable now.
Forgot to mention the last long rafter beside the notch want to be a 2 ply and the short at the top of the notch is a 2 ply out to the post. I did draw them in.
