At Yorkshire Roof Windows, we know how important it is to choose the right components when installing roof windows. One of the most critical components for ensuring a watertight seal and proper integration with your roofing materials is the flashing.
VELUX offers a range of flashings tailored to different roof types and materials. Here’s a guide to help you understand the various options and which one is best suited for your project.
What is Window Flashing?
Flashing is a thin, weatherproof material installed around roof windows to prevent water from entering the building. It helps protect against rain, snow, and wind, ensuring your roof window remains watertight. VELUX offers several types of flashings designed for different roofing materials and installation conditions.
Types of VELUX Flashings
- EDW – Standard Flashing for Profiled Roofing Materials
- Best for: Tile, Slate, and Other Profiled Roofs (up to 120mm in height)
- The EDW flashing is designed for pitched roofs covered with profiled materials like concrete or clay tiles. It features pleated sides for a snug fit and provides excellent protection against leaks. This flashing is ideal for those looking to install VELUX windows in standard roofing with a more pronounced profile.
- EDL – Flashing for Flat Roofing Materials
- Best for: Flat Tiles, Shingles, or Slates (up to 8mm thick)
- If you have a roof with flatter materials like slates or shingles, the EDL flashing is a perfect match. Its design ensures that the window fits seamlessly into the roof, providing a sleek finish that blends with the roof’s aesthetics while keeping moisture out.
- EDZ – Flashing for Interlocking Tiles
- Best for: Interlocking Tiles
- The EDZ flashing is specifically engineered for interlocking tiles, which can sometimes present a challenge for standard flashings due to their shape. This flashing guarantees a watertight connection and is particularly useful for roofs with larger interlocking tiles that need extra care.
- EDP – Flashing for Plain Tiles
- Best for: Plain Tiles (up to 15mm thick)
- For roofs covered with traditional plain tiles, the EDP flashing offers the most suitable option. It is designed to accommodate the slight variations in plain tiles, ensuring a perfect fit that will prevent leaks.
- EBW – Combination Flashing for Multiple Windows
- Best for: Side-by-Side Installation of Windows
- If you’re considering installing more than one window side by side, VELUX offers combination flashings like the EBW. This type of flashing is tailored to fit multiple windows, allowing for a continuous and streamlined finish across the roof. It’s ideal for creating larger, brighter spaces.
- EKW – Flashing for Roofing Felt or Bitumen Roofs
- Best for: Felt and Bitumen Roofs
- This type of flashing is designed for roofs covered in bitumen or roofing felt, commonly found on flat roofs or extensions. The EKW ensures a watertight connection between the roof window and the specific roofing materials used in flat roofs.
Choosing the Right Flashing for Your Project
Selecting the right flashing depends on:
- Roof Pitch: Certain flashings are better suited for specific roof angles.
- Roofing Material: Ensure that the flashing is compatible with the material used on your roof, whether it’s tiles, slates, or felt.
- Number of Windows: For installations involving multiple windows, combination flashings can save time and ensure a consistent appearance.
