Product Description
Master Flash Standard Fixing Kit
Model: 12-SK1
Install a compatible Master Flash or MI-Flash roof flashing with the Master Flash Standard Fixing Kit. The kit contains the sealant, screws and protective caps needed to secure a flashing to a suitable roof surface.
The supplied silicone helps create a weather-resistant seal beneath the flashing base. Meanwhile, the screws hold the base firmly against the roof. The caps then cover the screw heads to create a neat finish and provide added weather protection.
The number of kits required depends on the size of the roof flashing. Please check the guide below before ordering.

Why Use the Correct Fixing Kit?
A roof flashing must create a secure seal around the pipe and across the roof surface. Poor fixings or unsuitable sealant may allow the base to lift, move or leak.
This kit provides matching installation materials for compatible flashings. Therefore, it helps the installer achieve an even fixing pattern and a neat finish.
Larger flashings need more fixing points around their bases. For this reason, No. 7, No. 8, No. 9 and MAXI flashings require more than one kit.
Installation Guidance
- Check how many fixing kits the selected flashing requires.
- Make sure the roof surface remains clean, dry and sound.
- Form the flexible flashing base to match the roof profile.
- Lift the base and apply the supplied silicone underneath it.
- Return the flashing to its final position.
- Fit the screws evenly around the outside of the base.
- Tighten each screw enough to form a secure seal.
- Do not overtighten the screws or damage the flashing base.
- Fit the protective caps over the screw heads.
- Inspect the finished seal before completing the installation.
Always follow the instructions supplied with the roof flashing. The roof material, flashing size and installation conditions may affect the correct fixing method.
Important Installation Information
- Confirm the required number of kits before ordering
- Use fixings that suit the roof surface
- Apply the silicone to a clean and dry surface
- Space the screws evenly around the flashing base
- Do not overtighten the screws
- Check every fixing point for a complete seal
- Follow all relevant roofing and flashing instructions
Working at roof level carries a serious risk of injury. Use safe access equipment and ask a competent installer to complete the work where needed.
