Product Information
Full details
The Site Tile Flashing (1140mm x 1180mm) is a critical component for professional builders and DIY enthusiasts seeking to protect roof window installations from water ingress, corrosion, and snow buildup. It provides a highly durable, weather-tight seal that ensures the longevity of the window assembly in harsh environments; however, installers should ensure the roof tile profile is compatible with the flashing dimensions before beginning the installation process.

FAQs
Is this flashing suitable for all roof types?
This model is specifically designed for tiled roofs. It may not be compatible with slate or metal sheet roofing.
Can I install this on a flat roof?
No, this flashing is designed for pitched roof installations to ensure water runoff.
Does the kit include all necessary fixings?
Yes, the kit is designed to provide a complete weather seal, but always check the included hardware list against your specific installation manual.
How often should I inspect the flashing?
At least twice a year to remove debris and ensure the seals remain intact.
Can I paint the flashing to match my roof?
While the finish is durable, we recommend against painting as it may void the material integrity or affect the weather-tight coating.
Troubleshooting
Water pooling near the flashing edge
Check for debris blockage in the drainage channel and clear away any leaves or sediment.
Flashing appears loose after installation
Verify that all clips and nails are fully engaged with the roof battens and the window frame casing.
Difficulty fitting flashing to tiles
Ensure the roof tiles are correctly dressed and trimmed near the window; do not force the flashing if tile obstruction is present.

Setup, Compatibility & Care
To install, ensure the window frame is securely fixed to the roof rafters. Position the bottom, side, and top flashing sections in sequence, ensuring that each overlap correctly directs water downward. Always ensure the flashing is nailed or clipped according to the specific manufacturer guidelines for your roof substrate. For ongoing maintenance, perform a visual inspection twice yearly—ideally before winter and after the spring thaw—to clear away leaves, pine needles, or debris trapped in the flashing channels. Keep the area around the flashing clear to ensure unobstructed water flow.
