So I plan on building a patio roof over the back of my home. 32' wide by 16' deep. I have several roof lines and angles that intersect back there so I plan on using SkyLift roof risers to support the upper ridge beam. (Sorry if my terminology is incorrect, I'm not a carpenter....)
I also plan on using Perma-Columns for the lower side.
So here's the issue. I have no idea on what to size the framing lumber to. I'm thinking a LVL or glulam being used as the upper and lower ridge beams, 3.5" wide. I don't know how many risers or columns to use either. I will be using the galvanized HD risers and 6x6 Perma-Columns. I have to have a minimum of a 10lb snow load, 90 mph wind rating, and I'll be using standard roofing materials, aka architectural shingles.
I also want to clad it in siding on the posts and underside to give it the clean look and help preserve it. But that will come later. Along with fans and lights.
So what size LVLs, rafters, what spacing to use on the rafters, and how many columns and risers?
I'm guessing, usually to overkill standards by using 4 each of the columns and risers. That gives a span of under 10' between each. I'll also have an eve or overhang at the top and bottom. Probably 1' at the top, 2' at the bottom, and the outer columns and risers located at least 1' inside the outside roof edges.
I don't have any plans drawn up, can't find anything either, and really don't want to pay $1k for someone to do this. Any suggestions?
