I am building a patio cover over a recently poured concrete slab, my main concern is the span between posts. I have included a diagram of my plan. I live in central Texas, not much rain and no snow to worry about. When I had the slab poured i was not planning on building a cover, since then I've decided to cover it to protect from rain and the sun. I do not believe the slab will support the structure and I don't want to attach to the house. Will I have any problems with the spans or do you see anything else that needs correcting before construction?
Thanks, i was trying to avoid connecting to the roof, there is an existing gutter on the roof that I was hoping would catch runoff, I thought the gap might also act as a vent for the patio as it gets quite hot here in the summer, the patio will not be closed in on the sides. I was basically trying to construct a free standing structure that happens to be close to the house Yes I was sinking the posts down 24" in concrete. I'm going with a low pitch (3/12) with shingles or a asphalt rolled roofing. Is this just a problem waiting to happen or do you think it will work?
