Affordable natural roofing slates of good overall quality make the SIGA Classic range ideal for budget conscious projects. Although they require more sorting and grading to produce a good roof finish, all SIGA Classic roof slates must meet the same strict testing and certification criteria as the higher grades.

SIGA Classic range of natural slates are ideal for conversion and refurbishment projects across the UK, and are NHBC compliant making them particularly suitable for new build housing. Wastage is a little higher than the Commercial range.

All our SIGA Classic slates come with a 30 Year Warranty, terms and conditions apply.

Each SIGA natural slate product has a SIGA number – SIGA 120, SIGA 39 and so on. The SIGA number specifically defines the quarry and selection of slate, guaranteeing traceability and consistency that is second to none.
