Slate Locally Selected for your Project

The natural beauty of slate has been applied to great effect across our island; Each region has its own traditional requirements, some of which can no longer be met by locally produced slate.

SIGA Slate meets these needs with unique, carefully selected products. For example, we are the only supplier of randomly diminishing welsh slates suitable for use in Scotland. From a listed building to a housing development, you can find the slates which suit your project type and location using our Product Finder.

We also supply a range of reproduction stones and slates which have been developed to meet specific needs where natural stone or slate is no longer available. These include approved alternatives to natural Cotswold Stone, Collyweston and Swithland Slate.
