Product Description

MI-FLUES MI-Flash No. 5 EPDM Roof Flashing 101mm to 178mm Black

Part Number: 12-5LT

Seal a pipe penetration through a suitable roof with the MI-FLUES MI-Flash No. 5 EPDM Roof Flashing. It fits pipes with an external diameter from 101mm to 178mm and suits roof pitches from 0° to 18°.

The black EPDM material provides strong resistance to outdoor weather, ozone and ultraviolet light. In addition, the flexible flashing can follow the shape of the roof to help create a neat and secure seal around the pipe.

This No. 5 flashing has a 280mm x 280mm base and a maximum service temperature of 100°C. Therefore, always check the external pipe temperature and roof type before installation.

Suitable Applications

The MI-Flash No. 5 creates a weather-resistant seal where a suitable pipe passes through a compatible roof. For example, you can use it with correctly designed flue, ventilation and service-pipe installations when the pipe size, roof pitch and temperature remain within the stated limits.

However, this flashing does not replace any firestop, support or clearance required by the pipe or chimney manufacturer. Always follow the instructions supplied with the complete system.

How to Install the MI-Flash No. 5

1. First, confirm that the external pipe diameter measures between 101mm and 178mm.
2. Select the marked opening that provides a close fit around the pipe.
3. Carefully trim the EPDM cone with a suitable knife or scissors.
4. Slide the flashing over the pipe. If required, use a suitable lubricant to help it move into place.
5. Press and shape the base so it follows the roof profile.
6. Apply the correct sealant beneath the base as directed by the fixing-kit instructions.
7. Secure the flashing with suitable screws and caps.
8. Finally, inspect the whole edge and confirm that the base forms a complete weatherproof seal.

Take care when using cutting tools and working at height. A suitably competent installer should complete the work when the installation forms part of a chimney or flue system.

Check Before Ordering

• Measure the external diameter of the pipe, not its internal flue diameter
• Confirm that the pipe measures between 101mm and 178mm
• Check that the roof pitch falls between 0° and 18°
• Make sure the expected temperature does not exceed 100°C at the flashing
• Check that EPDM suits the roof covering and installation
• Order one compatible fixing kit if you do not already have the required fixings and sealant
