Single Ply Commercial Roofing
Bituminous Commercial Roofing
Adhesives and Cements
With over three decades of experience producing modified bitumen, we understand the science of formulating systems that last.
Our SBS is a premium modified bitumen engineered specifically for elasticity. It is made to withstand even the harshest environments.
SBS is the most customizable of our low-slow commercial roofing products with glass, polyester and composite reinforcements. It can be installed with the widest variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied applications.

Installation Instructions for JM Roofing Systems Urethane Adhesive (RSUA)
Use: For applying SBS cold applied membranes and insulation/ cover board. Used as a direct substitute for hot asphalt.
Type: Two-part, solvent free, elastomeric, cold application adhesive.
Color: Black to Brown
Features: 100% solids with no volatile organic compounds (VOCs). Low odor and fast set time. Can be applied over wide temperature and humidity ranges. High strength with exceptional wind uplift performance. Ideal for those applications where hot asphalt is prohibited, not desirable or not practical.
Meets the requirements of ASTM D 3019, Type III, Grade 2.
Use: For adhering roofing plies, modified bitumen membranes and for aggregate surfacings. It can be used as a direct substitute for asphalt in all JM modified bitumen roof membrane specifications.
Type: One-part, elastomeric cold application membrane adhesive.
Color: Black
Features: Cures to form a durable, elastomeric and watertight film. Cold process – does not have to be heated. Ready for use as shipped.
Use: For use with JM BUR and SBS membrane products. It is part of the JM PermaFlash® Bituminous Flashing System for penetrations and other details. Ideal for areas where hot asphalt is prohibited, not desirable or not practical.
Type: Two-part, elastomeric, liquid-applied flashing material.
Color: Black
Features: Cures to a durable, elastomeric film and forms exceptional bonds between the modified bitumen and underlying substrate. Resists virtually all factors affecting base flashing performance while providing superior flexibility and durability. UV stable, high solids, low odor, VOC compliant.
Use: As a substitute for asphalt and MBR® Flashing Cement in JM modified bitumen flashing details, and can be used to adhere the JM modified bitumen flashing systems and built-up roofing felts to vertical surfaces, as a general purpose mastic on most built up roofing and modified bitumen flashing details, or to strip in the laps of modified bitumen base flashings.
Type: One-part, asphalt-based, trowel-grade mastic.
Color: Black
Features: Cold process – does not have to be heated. Cures to form a durable, elastomeric and watertight film. Ready for use as shipped.
The PermaFlash System consists of PermaFlash Primer, MBR Flashing Cement, and PermaFlash Scrim. It is an integrated flashing system specifically formulated for use in bituminous systems.
