Vote for Your Winner of the Great British Slate Off 2026

The public will decide the winner of the Great British Slate Off 2026 following a too-close-to-call round of judging.

The competition, hosted by the National Federation of Roofing Contractors (NFRC) in collaboration with SIG Roofing, took place on stage at InstallerSHOW from 23-25 June and attracted crowds from the public and exhibitors to watch and support.

Voting is now open, with the winner to be announced on Friday 3 July.

The competitors, Adam (AL King Roofing), Jacob (Signature Roofing SW), and Josh (1st Choice Roofing) were selected to take part in the public final following a call for entrants, with judges Matt Timby and Andy Rowlands recognising their potential in the craft.

Tasked with drawing their own design concept to cut in decorative slates, the competitors had just three days to turn their designs into reality, all whilst under careful inspection from judges and visitors from across InstallerSHOW, contributing to the already challenging task.

“We knew the quality of work would be impressive, but what we’ve seen has gone above and beyond expectations, and we’re blown away by what the lads have achieved,” said Andy Rowlands. 

“Matt and I were closely watching over the designs as they came together, noting key elements to help choose a winner but ultimately, when all the designs were finished, it was just too close to call,” Andy continued.
