The Durable Slate Company Tops International Group in CUPA PIZARRAS Best of the Best 2025

The 2025 CUPA PIZARRAS Best of the Best competition saw US roofing contractor The Durable Slate Company top the International entries before France’s Duhamel Couverture was crowned the ultimate global champion.

To enter, CUPA PIZARRAS asked roofers from around the world to send in application videos showcasing their best work on a completed project or one still in progress. Entries were then sorted into regional groups with a winner for each group selected by readers of the CUPA PIZARRAS blog.

This year, the entries to the International group were Teto Horn, Wasi, Mr. Shingle, and The Durable Slate Company.

Following the public vote, The Durable Slate Company was crowned the International group winner.
