Expert Verdict — Reviewed by the SuperArbor Pro Desk
Fiberboard cover board is a cost-effective substrate for BUR and modified bitumen assemblies, and the coated face should be laid toward the membrane for best bond. Keep boards dry before installation, since wood fiber is moisture sensitive compared to gypsum cover boards. For heavy membrane traffic or long-term storage loads, a higher-compressive-strength board may be the better pick.
Carry and stack boards carefully on the roof; a standard utility knife is the recommended cutting tool, so use a fresh blade and cut away from your body.
