The NEW UNIROOF ST - Close edge welding and service-friendly!

 UNIROOF ST 40mm Analogue Version - Also known as the Pup! - Supplied in Leister Carry Case.

Free Delivery Mainland UK...

The new UNIROOF ST automatic roof welder is the service-friendly partner for the welding of thermoplastic membranes on flat roofs and roofs with low slopes (up to 30°)

The UNIROOF ST makes it possible to weld all thermoplastic membranes, as well as EPDM sealing sheets. With its ultra-slim housing construction and movable transportation axle, the new UNIROOF ST can easily be used for close edge welding (within 100mm / 4 inches of the edge), on top of parapets, flat surfaces, and in confined spaces without resetting.

  • No converting: Thanks to the movable transport axle the UNIROOF masters welding close to the edge at or on top of the parapet.
  • Swiss Quality you can rely on.
  • The direct-driven, maintenance-free wheel (drive motor integrated in pressure wheel) leads to clearly optimized overall performance and is easy to service.
  • Field tested design for ergonomic handling, flexible relocating and optimal machine guiding.
  • Greater efficiency at construction sites: The new UNIROOF class brings an additional 38% higher welding performance compared to similar machines.
  • Welding roof structure profiles with special profile kit.
  • Supplied with Yellow 120V 16 amp UK Plug
  • Comes in Genuine Leister Carry Case


The integrated direct-driven, maintenance-free pressure wheel is attractive for its service-friendliness, higher pressure and significantly greater welding speed compared to competitive products.

The flexible roof structure profile kit eliminates hand welding and, at 17.5 kg / 39 lbs, the UNIROOF AT/ST can be conveniently transported anywhere.

The completely controlled closed-loop system - for drive, temperature and air volume - assures that processes and investments, for builders and companies alike, are safe.
