Our Lead Free Flashing from National Flues is the ultimate solution for your chimney roofing needs, suitable for tiled and slate roofs. Constructed from a robust and environmentally safe polymer-based material called Fast Flash, it features an aluminium mesh reinforcement and a stainless steel (S/S) cone for durability. The lower surface is coated with a butyl self-adhesive layer and is finished with a protective film to ensure the flashing remains pristine during storage and installation.

This versatile flashing can be used on roofs with slopes ranging from 20° to 45° and is compatible with external pipe diameters of 175mm (125mm internal diameter). Its flexible design allows it to adhere easily to almost all common building materials, including brick, concrete, metal, glass, and various painted surfaces. The self-adhesive backing simplifies the installation process, and it can be easily customised using a Stanley knife or plate shears.

For porous surfaces such as brick and concrete, pre-treatment with Primer is recommended to ensure a secure bond. All surfaces should be cleaned of grease and oils with appropriate cleaning wipes and lightly matted using an abrasive sponge for optimal adhesion.

• Prepare the surface by cleaning all areas of grease, oils, and contaminants with appropriate cleaning wipes. Ensure the underlying surface is dry and free from debris. • For porous surfaces like brick or concrete, apply a suitable Primer to encourage optimal adhesion. • Lightly abrade the area with an abrasive sponge to create a slightly mat surface that the adhesive can bond to more effectively. • Measure and cut the flashing to your required dimensions using a Stanley knife or plate shears. • Peel off the protective film to expose the butyl self-adhesive backing and firmly press the flashing into place, ensuring no air pockets remain. • Allow adequate curing time as per manufacturer instructions before exposing the installation to weather conditions. • Always check that the flashing adheres securely around chimney penetrations to ensure a waterproof seal.
