rafters cut short and timber nailed to them, is that ok?

[johns1999]

hi

i'm having a small first floor extension done with a hipped roof. the carpenter thought the existing rafters were sitting on top of the new steel beam whereas they were meant to be on the side of the steel and cut them too short by about 6". what he's done is nailed new 4x2 to each rafter he's cut short so that they can attach to the side of the beam and these run up just past the purlin. 3 of the rafters have been cut anyway with double trimmers to allow access from the loft into the new loft area.

i've attached a couple of pics but is that ok do you think? i've got the building inspector coming next week, but would appreciate some advice as to whether that's adequate and likely to meet building regs?

any advice appreciated, thanks in advance

Why ask a bloke on the internet when the person who needs to be happy with it is coming next week. Email your BCO son some pics?

Probably is OK, but as above, it's basically down to your SE and building inspector. The fixings will be the important bit, in our extension I was concerned about the splices old to new rafters but the SE didn't bat an eye lid.

Structurally it will be fine, as long as there is a reasonable number of nails. As the tiles are off, the rafters will hardly be carrying any weight, and the shear force at the end will be low.
Your building inspector will most likely have a different opinion, though.

As an unqualified person, wouldn't it be better with "the missing bit" added back in?
With a fresh bit of wood added on each side as a splint?

Unless he is a PI in which case just ask him to log on to this site and look at the photographs.
