Hi,
I'm putting a new flat roof on a single story building and just wanted to sanity check it please.
One end of the joists will be attached to the 2storey end of the house using a 7x2 wall plate bolted to the wall (m12 bolts) then joist hangers from that to the joists.
The other end will attach to the top of a single skin brick wall. I was thinking of sitting the joists on top of the wall and using tie down straps to secure. I'd use paint on DPC to cover the ends of the joists. The building control guy suggested building the wall up 2 courses and then using joist hangers (so there was brick between the joist ends and outside for damp), however I'm not convinced about using joist hangers right on top of the bricks - seems they're meant to be built in. Does it make a difference if you put a timber wall plate on top of the brick then joist hangers from the timber?
Any thoughts/suggestions?
Thanks in advance
