The Genius Roof SpeedFlash Full Kit is a faster installation method for waterproofing roof anchor brackets on slate roofs with a 3-inch head lap, developed by Genius Roof Solutions (Hallclip) as a streamlined alternative to the standard SolarFlash system. Rather than drilling or nailing through the slate, SpeedFlash uses a base and cap assembly designed to minimise slate removal, making it especially suited to 18-inch and longer slates.
Every SpeedFlash order includes a galvanised steel shield to protect the course of slate below while the top slate is being cut, and the system is backed by a 20-year warranty. SpeedFlash is not intended for 4-inch head lap composite slates, so confirming your slate's head lap before ordering is essential.

Minimises Slate Removal
The system is designed to reduce how much slate needs to be removed during installation, particularly beneficial on 18-inch and longer slates where minimising disruption matters most.

Spring Support for Secure Fit
A spring support is included to help maintain a secure, consistent fit of the SpeedFlash base and cap assembly once installed.
Weather Stop Foam Included
A foam insert seals the assembly, helping keep wind-driven rain and snow out of the roof space beneath it.
