A flat roof needs strong seam work, clean edge terminations, and reliable drainage. For this TPO Roof in Livermore, CA project, Mel’s Roofing completed a 6,500 sq ft low-slope roof upgrade for a local church facility using GAF EverGuard® TPO (60 mil) with heat-welded seams. TPO systems are widely used on commercial roofs because the seams are heat welded for strength, and white membranes are designed for high reflectivity.

What We Upgraded on This Roof
This project focused on practical upgrades that matter on a working commercial building:
New white TPO membrane (60 mil) for a clean, durable surface
Heat-welded seams to create strong, consistent seam bonds
Primed 1/4" DensDeck® cover board to support the membrane system and provide a strong bonding surface
New metal edge terminations for a clean perimeter finish
New drains to improve water management
New wood screens for A/C units to refresh and protect mechanical areas
Why TPO is a solid fit for low-slope roofs
For commercial flat roofs, TPO is often selected because it provides:
Heat-weldable seams designed for strong seam performance
White reflective membrane options that are commonly used to reduce heat gain
A proven membrane format installed in wide sheets for efficient coverage
Before + After
Flat roofs often develop trouble spots at:
Seams and transitions
Areas around vents and penetrations
Low areas where water can sit longer
That is why the details matter as much as the membrane.
