I have a 910mm wide opening (excluding door frame) in a lean-to porch that needs re roofing in tiles across the whole. LHS is brick, RHS is (skinny) timber frame and glazed built on a half height wall.
My plan is to use a lintel/wall plate combo made from x3 4"x2" treated timbers as show on drawings.
1. Do you think this is sufficient?
2. Is it ok that it will bear onto masonry one side and timber the other?
The two roof sections need a new construction for tiles across the whole, as the old design had two parts with differing wall plates and projecting out to two elevations- the gutter across the front had a zig zag mess, joining the two parts.
I have to build up the wall on RHS to door header height, and build in a lintel that can bear tiles from the 3330x2550 roof, across the door. Rafters (6"x2") at 400mm centres.
I made below post in the wrong place, where 'CDBE' has kindly advised I need not run the 'wall plate/lintel combo' all the way across. I was a bit stuck on how to integrate masonry on one side, across a doorway and onto timber framework so fancied the one-piece solution, but with the doubled up 4"x2"s on top of the wall plate.
Any thoughts/advice gratefully received

Re roofing tricky lean-to with split level wall plate. Wall plate/header combo from 3x 4"x2" is ok?
Hi and thanks for taking the time to look and hopefully advise... :p Short form; see pics and Q: Will this 'beam'/wall plate/header/design for over the doorway aptly support the rafters, or is there a better way? Longer version; We have a single skin brick lean-to with half pan tiles and half...
