FIBERBOARD ROOFING SUBSTRATE
COMPLETES A PROJECT RELIABLY AND ECONOMICALLY
Durable and dependable, fiberboard roofing substrate helps you stay on top of any roofing application. As basic as a standard
built-up roof, yet as current as today's latest single-ply systems, fiberboard is durable and consistent, easy to handle, easy to
apply, and lasts for years in both re-roof and new applications.
