I built a tiny house on a trailer with no problem, but this freaks' me out. I am building a 14'x 44' pergola on a 3-1/2" cement slab. It has a 10'x 44' foot footprint, with 2' overhangs. The beams are 6x6x9 and 6x6x10 to cantilever over the roof of the house (I am fine with 8x8 if necessary). It will have a 1" standing seam metal roof. My intention is to use double 2x10's (I am fine with 2x12 if necessary)to support theon the rafters .The rafters are 2x6x14 @ 24 o.c. I will using ornamental wood ties/ post base, etc. What would the max span be between the beams (the 44'length)? Am I correct in thinking this is sufficient support? Thank you very much, I tried to be thorough.
