VELUX Standard Flashings 114x118cm EDW SK06 0000
Typical applications
This flashing is designed specifically for VELUX EDW skylights and standard roof ventilators installed in timber frame roofs. It suits multiple roof configurations and pitch variations, making it suitable for both new installations and replacement work on existing ventilation or skylight units.
- VELUX EDW skylight installations
- Standard roof ventilator sealing
- Timber frame roof construction
- Pitched roof applications with varying angles
Installation and positioning
The flashing must be positioned around the perimeter of the ventilator or skylight opening before the unit is secured. The 114×118cm size is engineered to overlap the roof covering and create a continuous weather-resistant seal. Ensure the flashing sits flush against the roof surface and the ventilator frame, with all edges properly secured to prevent water pooling or wind lift. The durable plastic construction allows for adjustment to accommodate minor roof pitch variations.
- Position flashing before fixing the ventilator or skylight
- Ensure complete overlap of roof covering on all sides
- Secure all edges to prevent movement or water ingress
- Check for gaps or misalignment before final sealing
Maintenance and durability
The weather-resistant plastic finish is designed for long-term performance in UK roof conditions without routine maintenance. Periodically inspect the flashing after severe weather to ensure the seal remains intact and no debris has accumulated around the edges. The air-tight performance is maintained through the integrity of the seal, so avoid disturbing or damaging the flashing once installed.
- Inspect after high winds or heavy rainfall
- Clear any debris or moss from around the flashing edges
- Check for cracks or deterioration in the plastic finish
- Do not attempt to repair damaged flashing; replace if compromised
