‘Guiding you through the optimised selling of Roofing Materials’
SIG are the largest distributor of natural slate in the world and quality is at the forefront of everything we do. We source our slates direct from the quarries, ensuring selection and quality of our natural slates is second to none.
This gives you total traceability and consistency of supply, a critical factor in improving your roofing sales.
SIGA slates provide the industry benchmark for quality, consistency, traceability and value. All our SIGA slates are BSEN 12326 approved, CE labelled and grouped into different specifications so you know exactly what you’re getting.
All our ranges of natural slate are carefully tailored to suit merchant customer needs.
SIGA Natural Slate – Commercial Range
The SIGA ‘Commercial’ range provides high quality at great value. This specification comes with a 30-year warranty and is suitable for both new and refurbishment projects.
- All slates tested to BS EN 12326
- All achieve an T1, S1, W1 (≤ 0,6%) rating, complying with NHBC requirements for new building projects
SIGA Natural Slate – Classic Range
The lowest priced natural slates within the SIGA range. Classic slates often require more sorting and grading to produce a good roof. This makes them ideal for small patching jobs or low cost refurbishment work.
- 30-year warranty
- Most come with a T1 rating
Despite the lower price, all SIGA Classic slates meet the same strict testing and certification criteria as the commercial range.
