When it comes to long-lasting roof repair and waterproof sealing solutions, RoofBond Stretch from AdhesionXtreme® SARL stands out as a premium product engineered for durability, flexibility, and performance. This article explores its features, benefits, applications, and addresses frequently asked questions — all optimized for those searching for “RoofBond Stretch waterproof sealing tape.”
What Is RoofBond Stretch?
RoofBond Stretch is a specialized self-adhesive sealing tape with enhanced stretch or elongation capability. It is designed to seal roof penetrations, joints, seams, and other vulnerable areas where water intrusion is likely. Key characteristics include:
- Stretch / elongation capacity: RoofBond Stretch can elongate up to 60 % over its original length, making it ideal for dynamic joints where movement or expansion and contraction occur (e.g. roof seams)
- Thickness & build: Typically about 1.6 mm thick (depending on variant)
- Composition: Modified synthetic rubber adhesive laminated with UV-stable aluminium/polyester reinforcement. The adhesive surface is protected by a siliconized liner until application.
- Surface compatibility: Works with PVC, EPDM, TPO, bitumen membranes, concrete, tile, metal, glass, wood, masonry, and more
- Temperature & weather resistance: Can handle extreme temperatures (–30 °C to +80 °C) and is UV resistant
Why Choose RoofBond Stretch?
1. Flexibility Under Movement
Because of its stretch ability, RoofBond Stretch is apt for sealing areas that undergo thermal expansion, contraction, or structural flexing (e.g. roof joints, flashing interfaces). The tape stretches instead of cracking under stress, maintaining a seal.
2. No Primer Needed
One of its appealing features is primerless application — the tape adheres directly to clean, dry surfaces without needing a separate primer stage, speeding up installation and lowering labor costs.
3. Rapid Installation
With ready-to-apply tape format, it reduces labour time significantly compared to liquid sealants or sheet systems requiring adhesives, heat guns, or curing.
4. Durable & Warranty Backed
RoofBond Stretch offers high durability, with expectations of 20 years life and backed by a 10-year warranty (depending on local distributor conditions)
5. All-Weather Performance
The tape maintains integrity under heavy UV exposure, thermal cycling, dampness, and harsh climates. It resists cracks under thermal shock thanks to its flexible backing.
Typical Applications of RoofBond Stretch
RoofBond Stretch is versatile. Some common use cases include:
- Sealing around roof penetrations (vents, pipes, HVAC units)
- Sealing roof seams and laps on single-ply membranes
- Repairing flashing details and edge terminations
- Waterproofing gutters, parapets, and downspouts
- Sealing roof ridges or hips where movement is expected
- Emergency leak repair on metal roofs, concrete, or membrane roofs
- Use in modular housing, verandas, terrace areas, caravans, and mobile homes
Because it bonds to many substrates—including metal, roof membranes, masonry, tile, and glass—RoofBond Stretch is a universal choice in waterproofing contexts.
How to Install RoofBond Stretch: Best Practices
- Surface Preparation
- Clean the surface thoroughly: remove dust, loose particles, oils, and any contaminants.
- Ensure the surface is dry and not actively wet or frost covered.
- Clean the surface thoroughly: remove dust, loose particles, oils, and any contaminants.
- Cut and Align
- Remove the siliconized liner gradually as you apply, to avoid contamination.
- Overlap adjacent strips by at least half the tape width (e.g. 50 mm) for continuity.
- Remove the siliconized liner gradually as you apply, to avoid contamination.
- Apply with Pressure
- Use a roller or hand pressure to press the tape firmly into the substrate. This ensures full adhesion and eliminates air pockets.

- Detailing Edges
- Where the tape terminates at metal edges or flashing, press the edges firmly and optionally use a fillet bead (compatible sealant) to reinforce.
