Spraying foam over EPDM or other single ply
Bidding a job on an old epdm roof.

The epdm is "fully adhered", but if you find a loose corner, you can pull up the epdm and feel the adhesion letting go.

Should this be a tare-off, or can we use fastners to fix problem spots down and spray the foam over it.

You might be able to cut the epdm loose, screw dens deck down and foam over. If theres no moisture under the epdm.
