The Lead Free Flashing 20° to 45° with a black cone and black base is ideal for securing flues to tiled or slate roofs. Constructed from a polymer-based base material with an aluminum mesh reinforcement, this environmentally friendly flashing is both durable and flexible. The stainless steel cone ensures robustness, while the butyl self-adhesive layer on the lower surface makes for an effortless installation.

The base is easy to cut and mold with basic tools like a Stanley knife or plate shears. It adheres to a wide range of building materials including brick, concrete, metal, glass, and certain plastics. For porous surfaces like brick and concrete, pre-treat with Primer for optimal adhesion.

Ensure surfaces are clean and slightly matted using an abrasive sponge before installation. This versatile product can accommodate roof slopes as low as 5°, making it a versatile choice for nearly any roofing project.

Before installation, ensure the target substrate is clean and free of grease. For porous surfaces such as brick or concrete, pre-treat with a suitable Primer and use an abrasive sponge to achieve a slightly matted finish. Begin by carefully peeling back the protective film on the butyl adhesive layer only when ready to apply. Position the flashing accurately over the flue, ensuring perfect alignment with the roof's edge. Press firmly to ensure complete adhesion, and use a Stanley knife or plate shears for any trimming adjustments. Caution: Avoid premature removal of the protective film to prevent the adhesive from sticking during storage.

The Lead Free Flashing 20° to 45° is suitable for tiled and slate roofs, accommodating a wide range of roofing projects.
