Kwikslate is a unique low-pitch, high-performance slate roofing solution designed to prevent water ingress when slates are installed at pitches as low as 10°. Manufactured in the UK from fire-rated GRP, Kwikslate eliminates the issues commonly caused by plastic alternatives — it will never sag, distort, or burn.

It’s engineered to work seamlessly with any double-lap natural or artificial slate between 500–600mm, providing an invisible, permanent seal beneath each slate. Whether you’re working on a new build, extension, or renovation, Kwikslate delivers long-term reliability, simple installation, and peace of mind with its lifetime guarantee.

One Kwikslate is required per slate installed, ensuring a consistent, watertight barrier across the entire roof.

Ideal for both traditional and contemporary slate roofing, Kwikslate offers a simple, cost-effective, and future-proof solution for achieving low-pitch slate performance that lasts.
