Reducing a valley rafter

[DME1970]

Hello everyone,
I was wondering has anyone come across a situation whereby they needed to reduce the depth of valley rafters in a loft conversion as the current depth (290) obstructs, I was thinking reduce in depth and fix a flitch plate, I have a SE looking at it at the moment but Id be interested to know if anyone has done it as even using a flitch plate Im struggling to see how you would go about it unless you fixed it to the underside like an UA maybe providing you leave enough timber to bolt through?
Cheers

A flitch plate goes between 2 joist, and can be either metal, or as some suggest plywood. But you're not telling us a lot about the setup, so it's difficult to say much more. Is the too high joist in place at the minute, and needs to be reduced, or is one going in that needs to be lower than the adjoining joists. What about a steel RSJ instead.

No mate the valley rafters insitu (1950s mid terrace) or yes would be relatively easy as could use a flitch plate between 2 timbers as you discribed or a UB, a flitch plate can also go on one side of a reduced timber as I've used this method before on ceiling joists that were too shallow due to ceiling height restrictions so we had to spec 100x100 CJ with 75x10 flat bar bolted to one side to resist deflection, so with it being in place you can see the problem, cheers anyway thanks for replying
