CUPA ReadySlate is the world's first pre-assembled natural slate roofing system, combining hand-split natural slate tiles with modern modular installation technology. Each module contains six hand-quarried natural slate tiles (3.5mm thick) mounted on a waterproofing bituminous membrane, utilizing 100% slate that is split by hand with no additional treatment chemicals.

The four-step installation process can be completed by any qualified roofing contractor quickly and cost effectively, without requiring specialized slate contractors. Pre-assembled modules ensure complete waterproofing and seamless integration, while natural slate retains its natural beauty and remains unchanged over decades. With low environmental impact and efficient production requiring minimal water and energy, ReadySlate represents a sustainable roofing solution.
