A TPO roof combines membrane, substrate, insulation and connections. Planning considers the complete assembly, the building and the selected system.
Prepare a suitable substrate
The existing deck, boards and attachment method guide preparation. Wet or damaged areas need to be considered before a new membrane is installed.
Pay attention to seams and connections
TPO membrane seams are hot-air welded. Upstands, drains and penetrations require details compatible with the system and checks during the work.
Choose an assembly for the property
The proposal should identify the membrane, insulation, attachment method and details to address. A white surface can reduce solar heating; its condition and maintenance still matter.
Points to assess
- The current covering and substrate beneath the membrane
- Drains, parapets and penetrations requiring connections
- Planned insulation and attachment method
