LEISTER Seam Tester – Precise inspection for perfect sealing
The Leister Seam Tester is an indispensable tool for roofers and waterproofers for the non-destructive testing of overlap seams in thermoplastic membranes such as PVC, TPO, and similar materials. Especially in flat and pitched roof applications, it ensures maximum safety and quality during sealing work.
Thanks to the specially shaped test tip, the seam tester enables fast, precise, and efficient inspection without damaging the membrane. Faulty welds can be identified immediately and specifically reworked – for permanently tight connections.
The ergonomic wooden handle fits comfortably in the hand, ensuring comfortable and fatigue-free work even during long periods of use on the construction site.
Advantages
- Non-destructive testing of weld seams
- Suitable for PVC, TPO, and other plastic roofing membranes
- Precise detection of leaky or faulty spots
- Efficient work due to optimized test tip
- Ergonomic wooden handle for a secure grip
Application
For inspection, the seam tester is guided along the overlap weld seam. In case of faulty spots, the test tip penetrates the seam – this makes weak points immediately visible so they can be repaired directly.
Areas of application
- Flat roof sealing
- Pitched roof sealing
- Plastic roofing membranes made of PVC and TPO
- Roofing and tinsmith work
Conclusion
The Leister Seam Tester is the ideal inspection tool for anyone who relies on precise, fast, and reliable seam testing for roof sealing. Perfect for professional use on the construction site.

High customer satisfaction
Sticks like hell
Rating for the sealing adhesive: Top for roof repairs!
The sealant is easy to apply, adheres perfectly, even to damp surfaces, and remains flexible after curing. Highly recommended!
Very good
I've been using the seam closer for a week now, and I have to say, it's simply fantastic: lightweight, robust, and the black rubber caps are fantastic at preventing it from slipping off quickly. Absolutely top-notch.
Friend winding core
An absolute must-have! No more flat rolls, easy to use, and the even pressure ensures a seamless seam. Will be reordering immediately!
