The Genius Roof Zero Lead in 300mm x 5m is a self-adhesive, lead-free replacement flashing from Genius Roof Solutions (Hallclip), built around a butyl tape core reinforced with an aluminium finish. It offers a lightweight, easy-to-apply alternative to traditional lead flashing for general roofing repair, gutter and valley work, and in-roof solar installations.
Being self-adhesive rather than requiring dressing tools or heat, Zero Lead can be applied directly to most clean, dry surfaces, making it a practical option both for standalone roofing repairs and as a complementary flashing detail alongside in-roof solar mounting systems such as Solfit and GSE.
Self-Adhesive
Application Method
Aluminium Finish
Surface Reinforcement
Please Note: Zero Lead is self-adhesive: the surface must be clean and dry before application to achieve a reliable, long-lasting bond. Poor surface preparation is the most common cause of adhesion failure with self-adhesive flashing products.
Self-Adhesive Butyl Tape Core
The self-adhesive butyl tape backing bonds directly to most roofing surfaces without the need for heat, adhesive primers, or specialist dressing tools.
Aluminium-Reinforced Finish
An aluminium surface finish reinforces the flashing for durability and weather resistance, giving a neat, professional appearance once applied.
Lead-Free Alternative
As a lead-free replacement, Zero Lead avoids the handling, weight, and disposal considerations associated with traditional lead flashing.
Versatile Surface Compatibility
Suitable for use on most clean, dry roofing surfaces, making it a flexible option across general repair and new-build applications.
Suited to Gutter and Valley Repairs
Well suited to gutter and valley repair work where a quick, reliable weatherproof seal is needed without the complexity of traditional leadwork.
Compatible with In-Roof Solar Systems
Works well alongside in-roof mounting systems such as Solfit and GSE, providing a complementary flashing detail around penetrations and abutments.
