It has been for 88 years (1930s semi with rosemary tiled roof). It is 170mm deep X 65mm. Above, but separated by a bed of mortar, is a 75mm x100m wall plate supporting the rafters and joists. I'm adding some new 7x2 ceiling joists sitting on the wall plate and 18mm chipboard flooring to provide loft storage (3-400kgs). Roof covering will be replaced in a few years (flat concrete tiles seem to be popular in the area - don't know whether these are heavier than the existing). I think I'll have problems if I leave it as is and I know if it was a full loft job it would need steel in. I'd rather not take it out as there's a big lead cavity tray nailed to the back of it so wonder if I can reinforce it with an angle iron or flitch plate.
While I appreciate it may be an SE question any suggestions would be appreciated. Thanks

Sorry the photos aren't great it's sunny here!
