Flat Roof Drain Outlets

Suitable for most types of flat roof systems. TPE is suitable for hot air welding or for adhesive bonding.

Flat Roof Drain Outlets

Our flat roof outlets are used for the vertical drainage of rainwater from flat roofs.  

Available in two standard sizes and with either smooth or perforated flanges, the outlets are suitable for either heat welding or adhesive bonding.

Engineered for flat roofs with outstanding durability, flexibility, and easy integration into modern waterproofing membranes — choose the flange style that matches your drainage needs.

 

  • ✅ 100% TPE — no PVC or EPDM degradation
  • ✅ Vertical outlet design (low profile)
  • ✅ UV & chemical resistance (roofing sealants)
  • ✅ Simple retrofit & new construction
  • ✅ TPE flange allows thermal movement of roof membrane while maintaining watertight seal.
  • ✅ Exceptional recovery and adhesion to bituminous, PVC, and TPO membranes.
  • ✅ No cracking over time, lightweight yet robust.
  • ✅ 100% recyclable & weatherproof

Unlike traditional PVC or metal drains, our TPE vertical outlets expand and contract with the roof membrane – eliminating leak paths. Choose a perforated flange for adhered membranes or a smooth flange for torch-applied systems.
