The Mayan ArmouredSlate system changes the way slate is installed. Our specially formed and patented GRP plate and weather system replaces the double lap that is normally required when slating, using our unique weathering bar and capillary strip.
When using the ArmouredSlate system, the roof is lighter, the performance is better, the installation time is quicker as well as saving 43% of the amount of slate that would normally be required.
The new Mayan ArmouredSlate system provides the aesthetics of a traditional slate roof. It is not possible to tell the difference between ArmouredSlate and a normal slate roof.
By using much shorter slates, twist and kickers are no longer a problem, resulting in a much more uniform installation.
ArmouredSlate is colour matched to the slates in a unique UV stabilised matt finish.
Complete the whole system with the Mayan RealRidge, including block and hip ends, as well as our groundbreaking Heritage valley.
Our slate, stone, ridge and valley systems provide the best performance available, and offer unsurpassed aesthetics.
Mayan have reinvented roofing to provide complete solutions for a modern roof with traditional looks.
The ArmouredSlate roofing system dramatically improves the overall performance of a slate roof.
The double lap layers used in standard slating are replaced by our ArmouredSlate, which is made from high performance GRP, with its excellent proven track record in roofing applications.
The front of the ArmouredSlate uses a forward weather seal to prevent rain blowing under the slates and stop them from rattling. Our unique weathering bar then provides a second barrier preventing any wind driven or capillary driven rain from tracking up the slate.

*ArmouredSlate is colour matched to the slates in Squirrel Grey, the white in the above illustration is only to show how it works.
Our standard ‘S’ type ArmouredSlate hooks over the batten.
The ‘P’ type ArmouredSlate is easily fixed directly to close boarding applications- Please contact us for more information.
Batten gauge can be adjusted in the usual way to accommodate the rafter run.
The slates are pre-holed to allow for additional peripheral fixing.
Choose from two slate styles, with our complete Mayan ArmouredSlate roofing system.
ArmouredSlate is made from well-known, tried and tested GRP, that has been used for over 40 years in roofing applications with consistent high-performance, long life and stability.
The GRP plate is positioned just below the slates to provide a resilient and completely waterproof layer, offering total protection against the very worst of the elements.
