Never seen this stuff before. Have done some Googling and wondering if it’s possible asbestos. Installed about 25 years ago.
Appears to be severely degraded fiberglass panel roofing. I would think no asbestos if installed 25 years ago or sooner. I see what appears to be fiberglass mesh in the second picture.
Thanks. Buyer was told maybe nylon?
Definately wasn’t hard like an asbestos cement, was really brittle.
Ondura or Onduline roofing panels
Cool. Let’s just say good thing the original roof is still underneath or it’d be pretty darn wet inside
