- Versatile Pipe Accommodation: The designed range of 275-450mm means fewer concerns about finding the right match for your roof. This versatility simplifies the purchasing decision by covering various installation requirements.

Installation Tips
Proper installation is critical to ensure the longevity and performance of your flashing. Follow these tips for a smooth installation process:
1. Preparation is Key: Before beginning installation, ensure that the area around the pipe is free from debris and that the underlying roof structure is in good condition. Clean surfaces always promote better adhesion.
2. Apply Sealant Generously: For a secure bond, apply a high-quality silicone sealant to the back of the flashing. This not only aids in watertight installation but also adds an extra layer of protection.
3. Precision with the Pull Tab: Utilize the pull tab design to adjust the opening of the flashing to match your specific pipe diameter perfectly. This feature is particularly valuable as it allows for a custom fit without the need for precision cutting.
4. Secure Fastening: Once the flashing is positioned correctly over the pipe, fix it securely to the roof. Consider using roofing nails or adhesives recommended by your roofing specialist to ensure a lasting installation.
5. Final Checks: After securing the flashing, inspect the installation for any gaps or misalignments. These minor details can significantly affect the performance of your roof flashing.
6. Safety First: Always adopt appropriate safety measures when working on a roof. If you are unsure about any part of the installation process, it is recommended to hire a professional installer.
