Im in PA where we do get some snow, they require a 30lb load bearing. In Texas I added a small awning/patio cover to my house by attaching directly to the fascia board. I gather that is not acceptable here.
I am thinking about 13' by 20' foot, preferably polycarbonate? plexiglass smoked translucent roof. I have a 16" soffit.
I dont want to put a ledger under the soffit, because a door opening is only 6 inches below the soffit.
I dont like going back on the roof, and putting it on the shingles, as that would probably mean greater than 12' roofing sheets.
I don't like just using asphalt shinges everywhere because I want more light.
I thought about bolting the 2x8 patio joists to the 2x8 roof joists (16" OC) that angle down and connect to the soffit. That is, I remove the fascia board, and either attach a ledger board to the end of the roof joists and the patio joists on the other side, or by simply bolting the two joists together. However I read that that is not ideal as the wall top plate becomes a teeter totter and can break the joists.
Another option, is to cut back the roof and run the patio joists to lay on top of the house band joist top plate, or attach the joists to the house band or to a ledger attached to the house band. That would mean removing some of the existing roof, making the project hard to undo, and I am concerned about
the patio roof being too thick, or thicker than the ashalt shingles, and how to accommodate that.
I had originally wanted one of the flat metal, built-in gutter type of roofs that my parents had in Virginia, but I have not found them, and I don't know if I could just attach them to the fascia board like my parents house, as if the codes have changed in 40 years for that.
And the last option I have thought of is to add three support posts with a beam/ledger next to the house so to make it free standing, but attached to the roof? And I dont like the extra holes to make and the appearance of these additional posts.
Any suggestions? Am I overlooking something?
