This pitched roof flashing is designed for Warmflow HE vertical balanced flue systems and provides a secure, weatherproof seal where the flue penetrates a pitched roof. Its conical profile adapts to the concentric flue diameter while allowing installers to maintain the correct termination height above the roofing surface. When installed correctly, it prevents moisture ingress and protects surrounding roofing materials.
The flashing is suitable for a wide range of roof pitches, making it a flexible choice for properties with varied roof designs. By integrating directly with the Warmflow Easy-Fit vertical system, it ensures that the flue remains stable and correctly supported as it passes through the roof structure. This helps maintain safe combustion performance and ensures compliance with installation guidance for oil boiler flues in dwellings.
Manufactured from durable, weather-resistant materials, the flashing is built to withstand long-term exposure to rain, UV and thermal cycling. When paired with the VBF vertical kit and optional terminal guard, it contributes to a secure, low-maintenance vertical flue arrangement for Warmflow HE boilers.
- Creates a weatherproof seal for pitched roof penetrations
- Compatible with Warmflow HE vertical flue systems
- Flexible cone for various roof pitch angles
- Durable construction for long-term outdoor performance
- Supports stable and compliant vertical flue termination
