Need to know a couple things. How long has it been since the hail damage, and to what extent was the size of the hail and the breaks, and what type of coating is on the roof?

dude, I wrote a paper on repairing hail damaged SPF roofs quite a few years ago. SPFA's Technical Committee used large portions of it for a technical guideline. You can download at sprayfoam.org document number AY 139 Repair of Hail Damaged SPF Roofing Systems.

Also, call me to discuss your specific application. 571-239-5221

I am also on RICOWI's Hail Investigation Team

Thermal scan will tell the tale.
