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.

  • Where are you located some areas require higher snow load and this could Change the answer by quite a bit. – Ed Beal Aug 23 '19 at 20:54
  • Hi Ed. Thank you for responding so quickly. I am in Sacramento CA, no snow. – litewrkr Aug 24 '19 at 0:55
  • Well I I grew up not far west but a costal zone and my little brother lives in auburn and he built his home, as the snow load is different in each zone can you tell me your elevation and how far from the coast or provide GPS locations? Not sure if I have much time to look things up but , I sold 10 acres we had and planned to build on because the county has crazy rules and the sessional stream turned out to be a class 1 fish stream, noth worth the trouble, but if you can provide the county, location and elevation we may be able to assist. – Ed Beal Aug 24 '19 at 2:32
  • Hello Ed. I live 40 min. west of Auburn, elevation 1200 ft, and on the Sacramento River at 20 ft. elevation. Sacramento has a hot-summer Mediterranean type climate , characterized by damp to wet, mild winters and hot, dry summers. The Latitude and longitude coordinates are: 38.575764, -121.478851. Thank you for your kind consideration. – litewrkr Aug 24 '19 at 4:04

These may be of help to you:



You will need to estimate your live load.

  • Residential live load is 40 lbs. per square foot, per Code...unless deck, etc. and not waterbeds or refrigerator. – Lee Sam Aug 27 '19 at 19:56
