Thanks.
On the basis of that one pic its maybe an attempt at sistering (now known as brothering) the existing rafters to strengthen them or straighten them out.
Thing is, there's barely any fixings to be seen - unless they've been fixed from the other side? But even then, we most always bolt-on when sistering (or brothering) & no bolting-on can be seen.
- so, in a sense, they are pinned there doing nothing that i can see? Do you have the mortgage surveyors report from the house sale?
The fixings look to have been shot in (professional?) but the nearest length is cupping (non-professional: the cupping should have been facing the rafter).
Hopefully, others will give you better advice than me?
Looks like some attempt at sistering. They're only nailed on one side, no bolts, and aren't connected near the soffit, they look to offer little support.
No further ahead - except its not cut rafters but a trussed roof, and the latest pics show a gap between the truss rafters and the new lengths?
There's no way that the soffit would need new lengths for the remedial fixing of rotten rafter tails.
No fixings have been removed.
My #4 deals with strengthening/cracks.
