Tremco Roofing and Building Maintenance, founded in 1928 and part of RPM International's Tremco Construction Products Group, sells fluid-applied roofing systems direct through a national sales-representative force rather than open distribution. Its liquid-applied portfolio spans the AlphaGuard family (two-part bio-based BIO polyurethanes, MT urethanes, PUMA polyurethane/methacrylate hybrids, and Si silicones) plus the single-component Geogard urethane restoration system. Systems are tied to Tremco's unified warranty program, including Plain and Simple and extended-term coverage at published gallonage rates, and the TremCare preventive maintenance program.
