Have you also considered the Edgemere interlocking slate range? With an 18mm thin leading edge, Edgemere provides an affordable upgrade to standard interlocking tiles and comes in standard, riven or duo formats, providing three distinct and slate-like finishes, for irresistible kerb appeal. 

All of our concrete interlocking tiles can achieve an 'A+' rating (which has the lowest environmental impact) in the Building Research Establishment's Green Guide to Specification.

Accreditation to the BES 6001 framework standard for 'Responsible Sourcing' means that projects using our concrete interlocking slates can now achieve extra credits under BREEAM and the Home Quality Mark (HQM). Click here to find out more.

*Please note* The British Standard for Slating and Tiling (BS 5534) has recently been updated, making significant changes to tile fixing requirements. To ensure that your roof is compliant with the new standard, our fixing specification service is available and can be accessed by clicking here.

Notes

The effectiveness of the tile or slate to operate at the minimum recommended pitch and lap may be influenced by special circumstances. Guidance on pitch and lap should be obtained from the Technical Advisory Service for the following:

  • Interlocking tiles and slates where the roof slope exceeds 6 metres in length and/or the site is rated to be in a severe exposure category.
  • Double-lap fibre cement slates where the roof slope exceeds 6 metres in length (severe/very severe exposure) and 9 metres in length (sheltered/moderate exposure).
