The quintessential slate look in the US
In recent decades, the tradition of using natural slate roofing in the United States has experienced a notable increase. Within this context, CUPA 14 has emerged as a highly regarded product, capturing the essence of slate roofing with its classic blue-black color.
Widely celebrated as the quintessential slate look by many across the country, CUPA 14 stands as a testament to the enduring appeal and quality of natural slate. Sourced from Las Fuentes in Spain, a prestigious quarry operating since 1985, our CUPA 14 has been part of the US market since 2008.
CUPA 14 is presently the closest natural slate on the market to historically produced slates like Buckingham and Peachbottom. Moreover, what truly sets CUPA 14 apart is also the assurance of quality and trust that comes with being produced by the world’s leading slate producer.
Production that stands the test of time
With almost 20 years of covering US houses, CUPA 14 is available at a standard thickness of 7.5 mm (1/4 – 3/8”) and can be produced in even thicker options.
Slate pieces per year
Every year we produce almost one million pieces of our CUPA 14 natural slate for the US market.
Installed roofs
More than 2,500 CUPA 14 slate roofs have been installed in the US, representing a trusted choice throughout the country.
Statues of Liberty
Over the years, we have exported CUPA 14 in quantities equivalent to the weight of more than 110 times the Statue of Liberty
