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.
The hidden interlock offers ease and speed of installation and gives the appearance of traditional double lap plain tiles. Ashmore is designed to perform at pitches as low as 22.5°, providing outstanding performance and versatility. With fewer tiles required to attain the traditional plain tile appearance, Ashmore is also highly cost-effective.
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).
*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 to the new standard, our fixing specification service is available.
