Choosing the correct flashings for your new or replacement roof windows is essential for a seamless installation and to ensure your home remains watertight. At Condell Ltd, our VELUX Flashing Kits are designed to integrate your roof windows perfectly with tiles, slates, or other roofing materials.
Determining Your Roof Material
Identifying your roof material and pitch is crucial in selecting the appropriate flashing kit. VELUX offers a range of flashings compatible with various roofing materials:
Flat Tiles (20°-90° Roof Pitch) - EDT Flashing: Suitable for flat tiles between 15mm and 40mm thick.
Slate Tiles (15°-90° Roof Pitch) - EDL Flashing: Designed for slates up to 8mm thick. Not suitable for interlocking slates.
