1960's GLB, cords delaminated.

Mark, RTU's too close or load not accounted for?

No, GLB delamination.

Any photos of the delam? Roofing was redone in the area, how long had it leaked and if so then why wasn't it observed earlier?
This will be a good "lessons learned case".

Going out there again today
Did not leak, no sign of water damage

My first thought was time had done a job on the glue and it became brittle. Is there not a shelf life on glue as it dries out?

Is there not a shelf life on glue as it dries out?

Gosh I hope not.

There will be a shelf life for glue in the bottle, but once it is incorporated into the assembly it should be forever.

Were they domestic or imported Glue-lams?
