Roof decking cement board asbestos?


80 year old raised house in New Orleans. New roof with plywood decking, looked nice. Got to the attic to see what appears to be old decking that looks like cement board. The stuff was cracked up like crazy and literally all over the place. Never seen cement board decking, if that what it is, but my bigger concern is asbestos. Consulted my roofer and he said it didn’t appear to be asbestos but would recommend test. Anyone come across something like this? Should I recommend asbestos test? Should the roofer who installed the new roof removed this existing decking rather than decking over it? Many thanks!


That does not look like cement board. That looks like an exterior gypboard that was never designed to be used as roof decking.
