In creating PermaMop® modified roofing asphalt, we didn’t just one-up regular asphalts, we’ve three-upped them.

PermaMop is versatile. It’s specially formulated for use on any slope of roof. It has the softening point of a Type IV asphalt but with a lower equiviscous temperature (EVT) than any standard Type IV. It stays where it’s mopped, even on steep-sloped roofing in intense heat.

PermaMop is long lasting. In laboratory testing, ordinary asphalt exceeds 60 weather cycles (approximately 15 years). PermaMop lasts a minimum of 150% longer – withstanding up to 193 cycles. Making it an ideal choice for projects in extreme weather areas – whether it’s heat, cold or moisture.

PermaMop is low fuming. Its composition includes a technologically advanced polymer additive. When heated, the polymer floats to the surface and creates a skim layer on the kettle that traps the fumes and odor inside – without affecting the asphalt or disrupting kettle operation.
