VELUX Recessed Flashings 55x98cm EDJ CK04 0000
Typical applications and installation locations
These recessed flashings are specifically engineered for installation in recessed roof areas where water ingress poses a risk. Common applications include flat roof junctions, balcony perimeters, veranda edges and similar areas where the roof plane is set back or depressed relative to the main building structure. The 55x98cm dimensions suit standard residential and light commercial roof configurations. Installation must take place in the recessed area itself, ensuring the flashing sits securely within the roof recess to create a continuous watertight seal.
- Flat roofs and roof-to-wall junctions
- Balcony and veranda installations
- Recessed roof areas where water pooling or run-off is a concern
- Standard residential and light commercial applications
Installation and on-site handling
The straightforward installation process makes these flashings accessible to experienced DIY users and trade professionals alike. Before installation, inspect the recessed roof area to ensure it is clean, dry and free from debris. The flashing must be positioned correctly within the recess to achieve the watertight seal the product is designed to deliver. Ensure all edges are properly secured and sealed according to the installation guidance provided with the product. Handle the flashing carefully on site to avoid damage to the material, which could compromise the watertight performance.
- Clean and dry the recessed roof area thoroughly before fitting
- Position the flashing centrally within the recess for optimal sealing
- Secure all edges firmly and check for gaps or misalignment
- Follow the detailed installation instructions supplied with the product
- Protect the flashing from damage during handling and installation
Durability, maintenance and limitations
The durable EDJ CK04 material grade is engineered to minimise maintenance requirements and provide reliable long-term weather protection. Regular inspection of the flashing, particularly after severe weather, will help identify any potential issues early. Whilst the flashing is designed for recessed roof installations, it is not suitable for applications outside its specified use, such as exposed roof edges or non-recessed areas. The product's effectiveness depends on correct installation; poor fitting or damage will compromise the watertight seal.
- Inspect periodically, especially after heavy rain or storms
- Clean debris from the recessed area to maintain water flow
- Do not use in exposed or non-recessed roof applications
- Repair or replace immediately if damage is detected
- Maintenance is minimal if installed correctly
