Slate is a natural material of hugely varying quality and selection, even from a single quarry. This can be a major concern for the architect and contractor, but the SIGA process provides you with confidence.
Confidence in Quality: Confidence in Supply
SIGA Slate carefully manages every single step of the journey, from the quarry to the roof. This monitoring and careful selection ensures that your slate roof is not only aesthetically beautiful and strong, but that you also have consistency and traceability that’s second to none.
Our slates are backed by genuine warranties of up to 75 years, proof that we truly believe that they can deliver.
All our slates are fully compliant with the Construction Product Regulations, are CE marked and traceable back to source.
Our own distribution network delivers SIGA Natural Slates, so you can be sure of reliability of supply.
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.
We Understand Natural Slate
Our team of experienced specialists have a genuine passion for natural slate roofing and we continually develop their skills and expertise to provide advice and technical support during the specification process and beyond.
Behind our nationwide branch network and specification team in the UK, our own experts source our slate and ensure its consistent quality and reliability, working direct with the quarries. We have built especially close partnerships with our quarries in Spain, where our onsite, full-time quality control teams at SIG Pizarras are all working together to make sure your slate is the best it can be.
