Guarantee
All of our products are designed and tested to work together. So not only is every product guaranteed weathertight, all the junctions between our products are similarly guaranteed. If any of our products fail during their first 15 years, we will not only replace them, we will also pay for the cost of labour and associated materials. Besides guaranteeing the roof tiles, this guarantee includes all our fittings and accessories. Indeed, the guarantee is so comprehensive that it is transferable to all future owners. A complete Redland Roofing roof is a completely guaranteed roof.

Slates will meet the requirements of BS 5534: Part 1: 2003: Code of practice for Slating and tiling, providing our fixing recommendations are complied with.
