When roof work keeps coming through the shop, waiting on membrane slows everything down. SuperFlex gives you bulk roof material to keep on hand for repair and replacement work.
For RV dealers and repair shops, a 400' roll keeps replacement membrane on hand for multiple roof jobs. This gray SuperFlex membrane measures 9-1/2' wide x 400' long and covers 3,800 sq ft per roll, giving the shop material to measure, cut, and stage as repair work comes in.
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, and the 30-mil material has increased thickness, tear resistance, and elongation compared with PVC roofing. Once positioned, your roof has a fitted membrane surface that follows the roof shape.
This roll includes the SuperFlex membrane only, so plan the rest of the roof install before the old membrane comes off. Alpha Systems water-based adhesive (AL87CV or AL27CV), butyl tape (AL32EF), self-leveling sealant (AL68KV), and non-sag sealant (AL33KV) are needed and sold separately. Don't use silicone sealant, because it won't adhere to the membrane.
Large shop rolls still require proper equipment and handling, but the membrane material itself is approximately half the weight of traditional EPDM roofing. The textured surface improves traction during installation and maintenance, while the UV-resistant surface resists fading, mold, algae, and fungus between periodic cleanings with standard household cleaners.

Alpha systems sealant is garbage. Do not buy!!! E trailer sold this to me and the product has caused damage to Adco cover. The sealant did not firm up and bonded to the RV cover. No help from E trailer or Lipperalpha systems. The covering is good but buy Dicor.. Thanks for nothing Etrailer. You were no help on this matter. I had to reseal the entire roof with Dicor. No refund from Etrailer or alpha systems. Absolutely no way to handle yourself Etrailer. Shame on you! Ill take my business elsewhere.
