Asphalt Roofing Systems
Tough. Reliable. Built for real-world conditions.
GenFlex™ Asphalt systems are designed to perform under pressure. These APP (plastic-like toughness and UV/heat endurance) and SBS (rubber-like flexibility and cold-weather resilience) modified bitumen membranes combine strength, flexibility and multiple layers of protection to handle harsh weather, tight schedules and demanding jobs.
Asphalt membranes offer benefits for everyone:
FOR ROOFERS
Fast, familiar installation with proven results in any climate.
For Design Pros
Reinforced redundancy and design versatility across systems.
For Building Owners
Durable, time-tested protection that delivers lasting confidence and value.
APP
GenFlex APP is a plastic modified asphalt system designed for quick installation, long-term UV resistance and durability.
SBS
GenFlex SBS modified bitumen
systems consist of a rubber-based polymer technology that delivers strength and flexibility,
even in extremely cold climates.
