Fixing and buying guide

Who this product is for

These flashings are ideal for builders, roofers, and experienced DIY customers installing or repairing roof penetrations on pitched roofs. They suit both new-build and retrofit applications where reliable weather protection is essential. If you are working with timber-framed roofs in the UK climate, this product provides the robust sealing performance needed to protect against driving rain and snow.

Compatibility and sizing

Check that your roof pitch falls within the 30–60° range before ordering. Confirm your timber frame grade is F16, F24, or F36. The flashing dimensions are 94cm length by 160cm width, which suits standard roof penetration widths. Measure your roof opening carefully to ensure this size matches your installation requirements. If your roof pitch is outside the specified range or your timber grade differs, this product will not perform as intended.

• Roof pitch must be between 30° and 60°
• Compatible timber grades: F16, F24, F36 only
• Dimensions: 94cm × 160cm
• Vinyl-coated polyester material resists UV and weather damage

What is included and pre-installation checks

Each pack contains one flashing unit. Before installation, inspect the flashing for any damage to the vinyl coating or polyester material, as this could compromise weather protection. Ensure your roof structure is sound and level, and that the timber framing is in good condition. Check that the opening you are sealing matches the flashing dimensions, and verify that all necessary fixings and sealants are available separately if not supplied with your order.
