Roofing Tapes
(3 Products)Roofing Tapes in this collection consist of high-performance, self-adhesive bituminous sealing strips designed for instant waterproofing. Featuring the industry-standard Bostik Flashband, these tapes provide a permanent, watertight seal on a wide variety of substrates, including brick, masonry, and timber, making them essential for urgent repairs and flashing replacement.
Understanding Roofing Tapes
Roofing tapes available here are engineered using a heavy-duty self-adhesive bitumen compound protected by a durable, reinforced aluminium facing. This composition creates a robust "peel and stick" solution, while offering excellent flexibility without the weight of lead. The bitumen adhesive is formulated to bond instantly to most building materials without the need for open flames, hot air guns, or separate glues.
The primary function of these materials is to provide a quick, permanent repair solution for cracks, gaps, and joints in roofing structures. The intrinsic flexibility of the bitumen adhesive allows the tape to mould to complex contours and corners, ensuring a secure bond even on irregular surfaces. This makes them particularly effective for sealing interfaces between different materials, such as glazing bars and brickwork.
Designed to withstand the rigours of external exposure, the aluminium facing provides UV protection and resistance to puncturing. The material is dimensionally stable and resists flowing or sagging under high temperatures, ensuring the integrity of the seal is maintained throughout seasonal weather changes.
Material Range
- Self-Adhesive Bituminous Flashing: This range consists exclusively of Bostik Flashband, a self-adhesive tape with a bitumen bond and a lead-look finish. Available in widths of 100mm, 150mm, and 225mm to suit varying joint dimensions, these tapes offer a universal solution for flashing, sealing, and waterproofing applications without the weight or installation complexity of traditional lead.
Performance Benefits
- Immediate Waterproofing: Creates an instant, watertight barrier upon contact, preventing water ingress immediately after application.
- High Temperature Stability: Engineered to remain stable under typical external temperature exposure, ensuring the bond remains secure in direct sunlight.
- Multi-Substrate Adhesion: Bonds effectively to felt, asphalt, slate, tile, brick, wood, glass, and many rigid plastics.
- Tear and Puncture Resistance: The reinforced aluminium facing protects the bituminous layer from physical damage and weathering.
- Cold Applied: Eliminates fire risks associated with torch-on products, requiring only hand pressure to secure.
Typical Applications
- Flashing Replacement: Serving as a cost-effective alternative to lead for chimney stacks, valleys, and step flashing.
- Roof Repair: Patching holes, cracks, and splits in existing bitumen felt or asphalt roof coverings.
- Glazing Sealing: Waterproofing the connection between conservatory glazing bars, roof lights, and the main structure.
- Gutter Maintenance: Sealing leaking joints or cracks in both metal and plastic guttering and downpipes.
Specification & Standards
- Tested to BS 476 Part 7 for surface spread of flame (where applicable)
Related Materials and Construction Uses
These bituminous tapes are frequently used in conjunction with bitumen primers when applying to porous, friable, or dusty surfaces such as old concrete or masonry to ensure maximum adhesion.
They integrate seamlessly with existing felt roofing systems, often used to seal overlaps or secure edge details where heat application is not feasible. In glazing and conservatory projects, the tape acts as a critical secondary seal alongside silicone or mastic beads to ensure a comprehensive watertight barrier around structural openings.
