Duhamel Couverture wins Best of the Best 2025

Duhamel Couverture has been awarded the Best of the Best 2025, following a closely contested final vote by a five-member jury. This recognition also marks France’s third consecutive win in the competition.

In the final vote, the French company secured 19 points, ahead of Haesen Rik Dakwerken (Belgium) with 11 points. The Durable Slate Company (United States) completed the podium with 9 points.

Also taking part in the final round were CP Roofing Solutions (United Kingdom), with 5 points, and Ardesia Couverture, which finished with 3 points.

In their assessment, the jury stated:

Duhamel Couverture’s proposal stands out for its attention to detail and for the clarity with which complex construction solutions were presented.

The Best of the Best 2025 decision was made by an international jury of highly respected professionals, including Matt Timby (United Kingdom), Heidi J. Ellsworth (United States), Severino González (Spain), Henri Lefin (Belgium) and Sébastien Therenty (France).

All jury members bring extensive professional experience and a strong background in the natural slate and roofing sector, ensuring a rigorous and well-balanced evaluation process. We would like to thank them once again for their commitment and continued collaboration.

Our thanks also go to the five finalists and to the 35 companies that took part in this year’s edition. Because beyond being a competition, the Best of the Best is, above all, a way to recognise the wonderful craft of the natural slate roofer and the value of work carried out to the highest standards.

We now look forward to welcoming Duhamel Couverture to our quarries, where they will have the opportunity to discover first-hand the origin of our slate. And to all other participants, we look forward to seeing you again in next year’s Best of the Best!
