Existing Gravel BUR Roof System
Existing Gravel BUR Roof System
Restore, protect, and extend the life of a variety of weathered gravel BUR roof systems.
AlphaGrade™ Roof Restoration System
Gravel-surfaced built up-roofs (BUR) deteriorate with age. Until now, all you could do was either replace the roof—which is expensive, labor-intensive, messy and disruptive—or restore it with aging, limited technologies. Tremco’s AlphaGrade restoration system changes that by enabling these roofs to be rejuvenated with an environmentally responsible, waterproof covering that will last for decades, with minimal stress for building occupants during installation.
