What this product is and who it is for

These flashings are specialist timber components for pitched roof construction in timber frame buildings. They are intended for builders, roofers, and experienced DIY customers undertaking roof work where weather protection and integration with VELUX roofing systems is required. The product provides a critical seal between roof elements to prevent water penetration.

Compatibility and sizing

This flashing is sized at 78×118cm and is suitable for roof pitches between 30° and 45°. Before ordering, confirm that your roof pitch falls within this range and that the flashing dimensions match your timber frame opening and roof specification. These flashings are designed to integrate with other VELUX roofing products, so check that all components in your roofing package are compatible.

Pre-installation checks

Inspect the flashing on delivery for any damage to the timber or weather-resistant coating. Confirm the product code EKWMK060021E matches your order. Check that your roof structure and opening dimensions align with the 78×118cm size. Verify roof pitch using a level or pitch gauge to ensure it falls between 30° and 45°. Store the flashing in a dry location until installation to protect the timber and finish.

• Check product code and dimensions against your specification
• Measure and confirm roof pitch is between 30° and 45°
• Inspect timber and weather-resistant finish for damage

Installation and integration

Install this flashing as part of your complete VELUX roofing system, following the manufacturer's installation instructions for your specific roof pitch and timber frame configuration. The weather-resistant finish protects against water ingress, but correct installation and integration with adjacent roof elements is essential for watertightness. Ensure all fixings and seals are secure and that the flashing sits flush with surrounding roof components.
