Fixing and buying guide

Who this product is for

These flashings are suitable for builders, roofers, and serious DIY customers installing or upgrading roof penetrations on pitched timber frame roofs. They work equally well on new build projects and retrofit applications where chimneys, vents, or skylights need watertight sealing.

Compatibility and sizing

The 78x118cm size is designed for standard residential and commercial roof applications. These flashings are compatible with roof pitches between 30 and 60 degrees. Before ordering, measure your roof pitch and the dimensions of the penetration (chimney, vent, or skylight opening) to confirm this product matches your requirements. If your roof pitch falls outside the 30-60 degree range, or your opening dimensions differ significantly, you may need an alternative flashing size.

• Roof pitch range: 30–60 degrees
• Flashing size: 78 × 118 cm
• Timber grade: EKL MK06 S0222 with protective coating
• Suitable for chimneys, vents, and skylights

Pre-installation checks

Inspect the flashing on delivery for any damage to the timber or coating. Check that your roof structure is sound and that the penetration opening is correctly sized and positioned. Ensure the roof pitch is within the 30-60 degree specification. Verify that the surrounding roof structure can accommodate the flashing dimensions without requiring excessive cutting or modification. Have appropriate roofing materials (slates, tiles, or covering) ready for bedding the flashing once installed.

• Confirm roof pitch is between 30 and 60 degrees
• Measure penetration opening to ensure compatibility
• Inspect timber and coating for transport damage
• Prepare roofing materials for bedding the flashing

Installation overview

These flashings are designed for straightforward installation on timber frame roofs. The flashing sits around the penetration and is bedded into the roof covering (slates or tiles) to create a watertight seal. The protective coating on the EKL timber helps resist weather exposure during and after installation. Follow standard roofing practice for flashing installation, ensuring proper overlap with surrounding roof coverings and secure fixing to the timber frame. Allow adequate drying time for any bedding mortar or sealant used during installation.
