Experiencing the vast variety of textures and colours that our roof tiles provide up close can guide you in the decision-making process when selecting roof coverings. Our efficient sample service can help you in this process.
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.
To ensure that your roof is compliant with the new standard, our fixing specification service is available.
