SIGA Slate web pageWhy choose SIGA Natural Slate?

SIGA Natural Slate stands for quality. We have in-depth knowledge of our quarries, where expert quality control teams work to ensure the slate is the best it can be. Apart from their obvious beauty, our natural slate ranges are renowned for strength, fire resistance, energy efficiency and durability.

Of that we can guarantee.

Product selection

Every quarry grades their slates into ‘selections’ during the production process. As there is no harmonised European or industry benchmark, there is little or no consistency across the market defining what makes a particular grade. Every quarry will aim to produce the highest possible proportion of best quality slates, with the lower grade slates more keenly priced.

To ensure you have greater transparency when selecting natural slate, all SIGA Natural Slates are categorised into either ‘Excellence’ or ‘Commercial’.

SIGA Excellence

 

Excellence

The finest SIGA Slates from the most reputable quarries, selected to provide a long lasting, beautiful roof with minimal grading and sorting, and very low wastage. Offers a readily-available alternative to long-discontinued domestic British slates, with a close match for texture and colour; no compromise on quality.

All Excellence slates come with warranties of up to 75 years.

SIGA Slate, Inverness, Macarthy and Stone.

 

Commercial

An affordable range of good quality slate. Ideal for the refurbishment & volume developer market. These are recommended for experienced slaters, as thickness and quality can be variable, so careful sorting and grading is strongly recommended for the best aesthetics. Comply with NHBC requirements.

All Commercial slates come with warranties of up to 30 years.

SIGA Heritage Reproduction Stone

Hand-crafted using moulds taken from stone slate originals, to give an authentic roofscape with shade variation, a choice of colours and a range of sizes. The glass fibre reinforced cement composition provides an extremely lightweight, yet durable roofing material. A range of compatible products, including ridges and in-line ventilation systems, create an extremely versatile and cost effective alternative to natural products.

SIGA Heritage Reproduction Stone roofing slates are designed to achieve an easy to lay slating format, resulting in a coursed and diminishing stone slate roof.
