Just looking for some advice on a patio cover idea I'm tossing around and would appreciate comments by those in the know.
The amount of my patio to be covered is 16'x21'. This will be an attached (via ledger board) patio cover and extend away from the house to cover the 16' width. My plan is for 2x8x16s for the rafters on 16" centers. They will span 14' or 15' with a 1' or 2' overhang. Roofing will be thin enamel coated metal roofing panels - not OSB and shingles.
The snow load requirement is 30psf. I've talked with the city inspector and he indicated since it is not a habitable structure, the code requirements are sparse and even the snow load may or may not apply to it. He simply said to submit my plans and if they don't "look stupid or dangerous", then I should be good to go. This didn't really answer my concerns as I was looking for actual guidelines to follow with my rafter and spacing choice. It seems every online calculator I find is for habitable buildings.
Do you think 2x8x16s on 16 inch centers is sufficient to be safe/solid and not sag when spanning 15' or 16'? Is this overkill? Underkill?
Thanks!
