Armoured Stone

Here at Truestone we believe in producing and selling quality products that we are proud to put our name against. Which is why we have partnered up with Mayan Roofing to showcase their ArmouredStone and RealRidge innovative roofing systems. Mayan roofs look exactly like traditional roofs, only they are much lighter, require less stone or slate and are easier to install!

Why is it unique?

Natural Stone | Long Life Roofing | 43% Less Stone | Low Pitch

Extremely high performance

Outstanding BRE test results as low as 17.5° on wind driven rain tests.

High-end aesthetic appeal

Looks identical to a traditionally laid stone roof.

Easy to install

Greatly simplified installation method for roofers.

Considerable cost saving

43% less stone
40% saving on labour
No structural roof


43% less stone, eliminating the need for a structural roof.

Mounting rails

Variable batten gauge

Available with fully vented, dry fix natural stone ridge.

Best performance

We tested a traditionally installed stone roof and directly compared it to the ArmouredStone system under the BS PD CEN/TR 15601.

Traditional stone roofs only remain waterproof on a pitch above 35°. Whereas the ArmouredStone system allows stone roofs to be installed as low as 17.5°.

Easy to install

ArmouredStone comes complete with a preinstalled mounting rail that simply hooks over the batten. The single lap use of the stones means that there is no longer any need for large, back breaking stone that is difficult to install.

ArmouredStone is now as quick and easy to install as roofing tiles.

Single Lap

The Mayan Stone roofing system changes the way stone is installed by using our unique and patented mounting rail with a specially formed GRP stone plate that replaces the lower double lap layers.

When using the ArmouredStone system, the roof is lighter, the performance is better, the installation time is quicker as well as saving 43% of the amount of stone that would normally be required.

No need for a structural roof

Because the ArmouredStone uses 43% less stone, it is 43% lighter. There is no need to install a structural roof frame.

At only 67kg / m², the ArmouredStone roof is similar in weight to a normal plain tiled roof. This means no more steel beams, large timbers or expensive calculations saving thousands of pounds.

How does it work?

The Mayan Stone roofing system utilises a specially formed GRP stone plate to replace the lower double lap layers.

*ArmouredStone is accurately colour matched to the stone in beige, making it invisible on the roof. The white in the above illustration is only to show how it works.

The Mayan ArmouredStone roofing system brings stone roofing up to date.

The versatile ArmouredSlate can be used with calibrated stone slates to bring a stunning modern look to this traditional roofing style.

Recycled stone can also be used to provide high performance at low pitch, that is indistinguishable from a traditional stone roof.

It can also be used with reconstituted stone slabs to provide a cost effective, lightweight solution to stone roofing.

Leading, innovative technology

Real stone offers a visually stunning roof that cannot be matched for its long life or appearance. The ArmouredStone system uses real limestone as a modern alternative to concrete or allows reclaimed stone to be easily re-used with the system.

The demand for a real stone roof is growing, but the traditional installation method means the roof is very heavy and cannot be installed on roofs below 35°, as well as being a highly skilled and expensive process.

The ArmouredStone system provides the solutions to all of these problems.

As the UK’s leading roofing innovation company, the team at Mayan is responsible for some of the UK’s most innovative roofing products over the last decade with a combined 40 years of roofing experience. Mayan have used skilled design and the most modern methods to develop the groundbreaking ArmouredStone system.
