The lightest natural stone roofing product on the market
Our affordable, high-quality 18mm Yorkshire Style natural stone roof slates ensure an extremely consistent shade while being relatively lightweight, almost 20% lighter than our 22mm option. These slates are ideal for projects with weight restrictions or where cost is a key factor, such as multi-property developments or larger builds.
Like our popular 22mm range, each Indian stone roof slate has a quarry-fettled edge and is calibrated in thickness to sit flatly and neatly on the roof. For ease of installation, each of these natural stone roof tiles is pre-drilled at 8mm to accommodate a 7mm aluminium fixing.
We supply a batten plan that is specific to your roof as standard, or we can easily accommodate a pre-designed batten plan thanks to the huge range of slate sizes kept in stock. We are more than happy to supply colour samples and sample roof slates that can be set up and left on site for assessment – especially for larger or more sensitive projects.
Our entire roofing range is also covered by our comprehensive lifetime guarantee, adding peace of mind and value to your property.


Product Specifications
Colour options: The look and feel of Yorkshire stone roofing

Standard Ash
Standard Ash is our classic 18mm Yorkshire Style roofing style, offering a subtle and attractive blend of grey tones to suit a wide array of roofing projects.

Light Aged Yorkstone
Light Aged Yorkstone takes the colour and shading of our 22mm option of the same name, offering an attractive blend of artificially aged grey tones and a traditional and long-lasting aged aesthetic.

Medium Aged Yorkstone
A slightly darker shade than our Light Aged option, these striking roof slates represent a comfortable balance between light and heavy ageing, allowing them to effortlessly blend in with a range of existing styles and shades, particularly for older properties.

Heavy Aged Yorkstone
The darkest of our Aged Yorkstone options, these heavily aged slates can be seamlessly blended into existing roofing on older, historic properties or where a darker roofing option is preferred.
Need something different?
If none of our roofing shades is exactly what you’re looking for, why not ask about a bespoke blend? Usually offered at no extra cost, we are happy to work with you to create a shade that suits your project. Just send us a photograph of what you’re looking for and we’ll take it from there.
