The complete TPO assembly
Membrane thickness is only one choice within a larger roof design.
- Deck and attachment approach
- Insulation and cover board
- Membrane and welded seams
- Curbs, penetrations, and walls
- Perimeter and drainage details
TPO roofing
TPO roofing with welded seams and coordinated details.
TPO is a single-ply thermoplastic membrane commonly used on low-slope roofs. The assembly may be mechanically attached or adhered, with heat-welded seams and system-specific flashings, edges, insulation, and accessories.
Repair and maintenance
Compatible preparation and welding are important when addressing punctures, open details, flashings, and prior repairs.
- Seam and flashing review
- Puncture and traffic-area repairs
- Drain and scupper maintenance
- Compatible patch preparation
Frequently asked questions
Questions about tpo roofing.
These answers provide a practical starting point. The building, roof assembly, permit jurisdiction, and observed conditions determine the final recommendation.
What is TPO roofing?
TPO is a thermoplastic single-ply roofing membrane used mainly on low-slope roofs. Sheets are joined with heat-welded seams and integrated with system-specific flashings and edges.
Is white TPO a cool roof?
White and other reflective membranes can reduce solar heat absorption compared with dark surfaces, but actual building performance also depends on insulation, assembly design, climate, and HVAC conditions.
Can a punctured TPO roof be repaired?
Localized punctures often can be repaired when the membrane and substrate are serviceable and properly prepared using compatible system materials and welding methods.
