Features to know about

Cover Smaller Roof Sections

Not every roof repair calls for a full-width replacement roll. This white SuperFlex membrane measures 4-1/2' wide x 10' long and covers 45 sq ft per roll, giving your roof a smaller sheet of membrane material for section repairs or patch-style work.

Fitted Coverage Over Roof Contours

RV roofs may look mostly flat, but crowns and molded roof shapes still need membrane material that can settle into position without losing strength. SuperFlex construction is flexible and stretchable while staying puncture and tear resistant, with increased thickness, tear resistance, and elongation compared with PVC roofing. Once positioned, your roof has a fitted membrane surface that follows the roof shape.

Know What You Need Before Installation

This roll includes the SuperFlex membrane only, so plan the rest of the roof repair before the old material comes off. Alpha Systems water-based adhesive (AL87CV or AL27CV), butyl tape (AL32EF), self-leveling sealant (AL98KV), and non-sag sealant (AL28KV) are needed and sold separately. Don't use silicone sealant, because it won't adhere to the membrane.

Roof Surface Protection With Lighter Material

SuperFlex material is approximately half the weight of traditional EPDM roofing, which makes smaller roof membrane sections easier to handle and position during repair work. The UV-resistant surface resists fading, mold, algae, and fungus, while periodic cleaning with standard household cleaners keeps the surface easier to maintain.
