Hi Rooster,
That is distressing news but at the same time informative. I would have thought that a timber frame left standing unsheathed would not have been very vulnerable to windthrow.
It should be possible to fit new "free" tenons to damaged beam ends especially if this is a square rule frame with fully housed joints.
This project might well now form a timber building conservation challenge rather than just accepting that the building is now fit only for salvage materials.
Some pictures would be helpful to be able to offer a more informed opinion.
Regards
Ken Hume
