Welding Flat Roofs

Flat roofs must be welded watertight to ensure long durability and to prevent water damage to the interior. Leister automatic welders and heat guns are the first choice when roofs need to be welded. Roofer’s require a welding machine that keeps setbacks to a minimum on the job site.
 

Leister automatic welders and heat guns are the first choice when roofs require welding. Roofer’s dream of a welding machine that keeps setbacks to a minimum on the job site. There is nothing more frustrating than a machine that fails during welding. Failures mean additional work and costs for roofers. They must be able to rely on their welding tools. Even when using a generator, the welding machines must function reliably.

Leister offers roofers the right solution with a complete range of automatic welders and heat guns to weld roofing membranes on flat roofs.

Flat roof, overlap welding

Leister offers economical and ergonomic hot air welders for overlap welds on thermoplastic roofing membranes. The tested and proven VARIMAT V2 automatic welder enables safe and fast welding, thanks to its patented, spherical roller, nozzle with high preheating capability and powerful hot air blower.

Tight and secure welds on flat roofs are produced quickly and safely, thanks to welding parameters that can be monitored and modified. (Even with exposure to unfavorable weather conditions.) 

The easy-to-handle UNIROOF AT/ST has proven itself in areas that are difficult to access, in close proximity to walls, smaller roofs and for narrow radii. The new, small, semi-automatic welder, UNIDRIVE 500, is suitable for edges and gutters. Prior to welding the base seam itself, the weld quality can be checked using the EXAMO tensiometer and accessories. Leister offers tested and proven heat guns for all work that requires extreme precision, including the TRIAC ST/AT, which is valued by users for its robustness and reliability.
