Why the BAK LarOn Hot Air Welder Is a Game-Changer for Roofing Membrane Installation

A seamless roofing membrane should provide a durable, watertight barrier for roofs, preventing water from penetrating the building structure. When working on a job site, you need to ensure the installation is done properly and within a reasonable time. The membrane also needs to be sealed tightly. A leaking roofing membrane can cause structural damage, mold growth, and increased energy costs. In addition to weakening the roofing materials and damaging insulation, water penetration through the membrane can also lead to staining and mold development.

A great tool for roofing membrane welding is the BAK LarOn Hot Air Welding Machine. Learn what it can do for you below.

The LarOn roofing hot air welder consistently delivers high-quality welds that fuse membrane overlaps into watertight seams. Hot air welding creates a stronger bond than adhesive methods because the hot air softens and melts the material surfaces and the joint interface. These softened materials are pressed together, allowing long polymer molecules to intertwine. Once cooled, the polymer chains solidify, forming a molecular bond that is often stronger than the original material.

This welding method also eliminates the need for messy adhesives or primer, reducing chemical exposure on the job site. And because the seams are uniform and machine-welded, the risk of installer error is significantly reduced, helping ensure long-term roofing performance.

One of the key advantages of hot air welding is speed. BAK's LARon machine has a welding capacity of up to 1,380 feet per hour (or 23 feet per minute), making it an excellent choice for large commercial roofs where both speed and consistency are critical.

Faster installations don't just save money, they also minimize exposure to heat, cold, and wind. When projects move quickly, teams can stay on schedule or even finish ahead of time, improving client satisfaction and opening up room for more projects throughout the season.

The hot air welder features an intuitive digital control panel that allows you to set the temperature for membrane welding or tarp applications. This reduces the risk of overheating or under-welding, either of which can compromise seam quality. You can also adjust the welding speed using the digital interface. Speed and temperature are determined by the membrane material, thickness, and environment.

Digital precision makes the LarOn particularly useful for jobs that require adherence to strict specifications or codes. Contractors working with a range of clients can benefit from the consistency and accuracy it provides.

The digital display and controls make the machine user-friendly for both new and experienced operators. Its ergonomic design makes it adjustable and easy to maneuver, even on slopes or near parapets. Weighing only 77 pounds, it's easy to transport around the job site. Additional features like an automatic drive start system, brushless motors, and a pivoting guide bar ensure smooth, uninterrupted operation, even on challenging terrain.

The learning curve is short, and many crews find that team members can become proficient in its use within hours. This ease of use helps reduce downtime and increases productivity on every job.

The adjustable temperature settings make the machine reliable in varying job-site conditions. Whether it's hot, cold, or lightly windy, the LarOn can maintain consistent welds. While hot air welding in cold conditions isn't ideal, it's still possible with BAK's technology, helping you maintain productivity year-round. For roofers working in areas with unpredictable weather patterns, this feature can be a game-changer. Rather than losing days due to equipment limitations, you can adapt and stay productive.

Over time, BAK's hot air welder pays for itself. Faster job completion saves on labor costs and reduces the likelihood of callbacks. Its durability results in lower maintenance needs and a longer service life, making it a smart long-term investment.

The robust build also reduces wear and tear, so your team can rely on it for project after project without fear of costly breakdowns.

The LarOn 21 High-Speed Automatic Roof Welder is suitable for welding TPO, PVC, and other thermoplastics, making it a versatile tool for various roofing systems. It can be used for new installations, repairs, or re-roofing projects, and is also effective for industrial tarp applications. Whether you're working on flat commercial roofs, curved architectural structures, or specialty coverings, the LarOn provides the flexibility to meet project demands.
