TPO is a single-ply thermoplastic membrane used on many low-slope roofs. Its welded seams and broad commercial use make it one option worth evaluating for compatible buildings.
Where This System Fits
TPO may fit commercial, multifamily and some residential low-slope roofs when the roof design, substrate, insulation and drainage support the system.
What We Evaluate Before Installation
We review membrane condition, attachment method, insulation, substrate, drains, curbs, penetrations, perimeter details and the existing roof assembly before proposing repair or replacement.
Installation Details Matter
The material name alone does not determine performance. Edges, transitions, penetrations, flashings, drainage and substrate conditions must be compatible with the selected system and installed as a complete assembly.
Repair or Replacement
A localized defect may be repairable when the surrounding system is in serviceable condition and compatible repair materials are available. Widespread deterioration, repeated leaks or substrate problems may justify replacement.
Important Considerations
TPO should be specified as a complete manufacturer-compatible assembly. Thickness, reinforcement, attachment, cover board, insulation and flashing details can materially change the finished roof.
