Extend the life of your natural stone roofing, using up to 43% less stone even at low pitches

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.

Roofs constructed with the ArmouredStone system look exactly like traditional natural stone roofs, only they are much lighter, require less stone or slate and are easier to install thanks to their suitability for varying batten gauges.

These extremely hardwearing roofs have achieved outstanding BRE test results, remaining waterproof on pitches as low as 17.5° on wind driven rain tests. An ArmouredStone roof can achieve up to 43% reduction on stone use, up to 40% reduction on labour time and entirely removes the need for a structural roof.

Proven 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°.

Easier installation, every single time

The ArmouredStone system 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, heavy stone that is difficult to install. A specially formed GRP stone plate replaces the lower double lap layers.

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, potentially saving thousands of pounds.

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.

Explored ArmouredStone

Click and drag your cursor to explore the ArmouredStone system using the 3D model below. Please note that ArmouredStone would be accurately colour matched to the stone in beige, making it invisible on the roof. The white in the illustration is purely to show how it works and to differentiate the system from the roof tiles themselves.
