AlphaGuard BIO 25 is a two-part, polyurethane, liquid applied roofing system that can turn your older but still functional roof into a long-lasting, highly efficient weatherproofing system by overlaying.
The system can waterproof over existing flat roof build-ups and structural roof decks.
It can also be used as a full system build up for either roof replacement or new build
construction projects.
