Make the Roof Leakproof!

By Roland Beeler and Gregor Studor, Leister.  

UNIROOF 700 with Leister Quality System (LQS Roofing) provides quality assurance to ensure leak-tight joints for a long-lasting roof. 

Versatile requirements for a flat roof 

Most people will agree that any roof should be impenetrable to the elements. But when it comes to flat roofs, that’s not the only requirement. The versatility of flat roofs allows them to support various elements that can benefit your roof, the building and the environment. Greenery on a flat roof helps not only the roof but the building stay cool in the summer months, while also supporting biodiversity.. Another example is solar cells, which use the sun's energy to generate electricity without releasing any pollutants into the environment. Furthermore, during rainstorms, flat roofs capture water, which helps reduce the strain on nearby sewage systems. 

Both you and your clients benefit 

Due to the increase in multiple uses, a reliably tight roof is essential for building owners, planners and roofers. As a pioneer in the construction of automatic roof welding machines, Leister takes this development into account with quality assurance LQS Roofing. Used for the first time worldwide in the UNIROOF 700 automatic roof welding machine, LQS Roofing gives you more control and safety when roof sealing. The automated data recording on LQS Roofing helps you document your welding work with ease. This not only helps you, but also reassures your customers. Simply activate LQS Roofing via the myLeister app and experience this new Leister service free of charge for the first 18 months. 

Digitally networked quality assurance in two stages 

The LQS Roofing System supports you in two stages during and after the welding process.  

1 - Immediate help with digital welding assistant: As soon as you leave the entered welding parameters during the welding process, the automatic welder signals and informs you with an acoustic and optical warning signal. Using a marker, you can check your weld seam immediately after completing the work with the weld seam tester. 

2 - Automatic welding reports: The LQS function automatically records the relevant welding parameters of temperature, speed and air volume. The data is presented in a PDF report and contains representations of the parameters as graphs and in tabular form including GPS coordinates.
