TPO is the membrane found on most current production RVs — reflective, durable, and built with heat-welded seams. It still needs the right repair methods and TPO-compatible materials. We repair, reseal, and fully replace TPO roofs.
TPO (thermoplastic polyolefin) is a newer membrane than EPDM and has become standard on most current production RVs. Its seams are heat-welded instead of glued, and its surface is highly reflective.
TPO generally needs less upkeep than rubber, but the vents, AC units, and edges still rely on sealant, and the membrane can be punctured or damaged. Using the wrong patch or sealant on TPO is a common cause of repeat leaks.
