How and where to use guide
VELUX EDW PK04 2000 + BDX 94 X 98 SINGLE TILE FLASHING
Typical applications and installation location
This flashing is specifically designed for use with rooflights and skylights installed on pitched tile roofs. It is positioned around the perimeter of the rooflight opening where the frame meets the roof surface. The flashing works in conjunction with your 94 x 98mm roof tiles to create a continuous weatherproof barrier. Installation is typically carried out during rooflight fitting or when replacing an existing rooflight unit. The flashing must be positioned before the surrounding tiles are laid to ensure proper overlap and water runoff.
- Rooflights and skylights on pitched roofs
- Roofs using 94 x 98mm tile format
- New rooflight installations or replacements
- Exterior applications requiring weatherproofing
Installation and positioning
The EDW PK04 2000 flashing must be carefully positioned around the rooflight opening to ensure correct water shedding. The flashing should be installed so that tiles above the rooflight overlap the flashing, allowing water to run down and away from the opening. Below the rooflight, tiles should be positioned to sit on top of the flashing. Proper alignment with your specific 94 x 98mm tile size is critical to avoid gaps that could allow water penetration. Follow VELUX installation guidance specific to your rooflight model and tile format to ensure the flashing is correctly seated and secured.
- Position flashing around complete rooflight perimeter
- Ensure upper tiles overlap the flashing for water shedding
- Align flashing precisely with 94 x 98mm tile dimensions
- Secure flashing according to manufacturer instructions before tiling
Durability and maintenance
The high-quality plastic construction of this flashing is engineered to withstand exposure to weather, UV radiation, and temperature fluctuations. The robust design provides long-term protection against water ingress and weathering. To maintain performance, periodically inspect the flashing and surrounding tiles for any signs of damage, displacement, or debris accumulation. Clear any moss, leaves, or dirt that may collect around the rooflight opening, as this can impede water drainage. If the flashing becomes damaged or cracked, it should be replaced promptly to prevent water leakage into the building structure.
- Inspect flashing annually for cracks or damage
- Clear debris and moss from around the rooflight opening
- Check tile overlap and flashing alignment after severe weather
- Replace immediately if damage is found to prevent water ingress
Important limitations and safety considerations
This flashing is designed exclusively for 94 x 98mm tile sizes and must not be used with other tile formats, as this will compromise the watertight seal. The flashing alone does not provide structural support and must be installed as part of a complete rooflight assembly. Installation should be carried out by competent roofers familiar with pitched roof work and rooflight fitting procedures. Work at height requires appropriate safety measures including fall protection and secure access equipment. Do not attempt installation in adverse weather conditions that could affect the quality of the seal or create safety hazards.
- Compatible only with 94 x 98mm tiles; do not use with other sizes
- Installation requires competent roofer with rooflight experience
- Work at height requires appropriate fall protection
- Do not install in wet or windy conditions
