So i have a patio area i would like to cover over.
3.7m x 4.6m
The plan so far is
Flat roof
For a 4.7m length i will need 9x2 joists from what i gather
So 9x2 wall plate bolter to external wall running 3.7m
10 9x2 joists will be hung off this spanning 4.7m
These will attach to a 9x2 bearer (will this need doublin up)
This will sit on 2 8x8 timber posts.
Does this seem right so far.
Roof will be covered in osb 18mm, then epdm, may have a roof light in there aswell
The posts will sit on t shape post bases
These will sit on 2 concrete piles i plan to dig out (not sure on the size these should be but i was going with 600 to 1m deep and 12 to 14 inch sq
I was also going with joist hangers as mounting them on top of the wall plate will make the roof/celling height a bit higher then what i would like.
Any advice or info would be great please
