The Great British Slate Off

Do you have the skill, precision and craftsmanship to stand out in the roofing industry? The Great British Slate Off is your chance to showcase your natural slating expertise and compete alongside some of the best in the trade.

This NFRC competition, hosted by SIG Roofing, invites roofers from across the UK to submit a short video demonstrating their slate roofing skills. The natural slate used in your project can be purchased from any supplier.

A panel of industry judges will review all entries and select three finalists to take part in the live Great British Slate Off final at InstallerSHOW 2026.

Finalists will receive three days of specialist ornamental slating training with NFRC, VIP access to InstallerSHOW, and the opportunity to demonstrate their craft on a national stage.

Whether you’re an experienced roofer or developing your skills within the trade, this is your chance to show the industry what you can do.
