Landmark Double Roman
Landmark Double Roman tiles combine Redland's special long-lasting Landmark surface finish with the popular Double Roman profile. Available in two authentic clay colours, they are ideal for maintaining the look of a traditional Double Roman roof at a considerable saving over new or reclaimed clay.
Landmark Double Romans are made using Redland's revolutionary manufacturing process, ColourFusion™. This involves fusing a very dense layer of highly pigmented amalgam with the top of the tile, so that it actually becomes part of the tile body, rather than a thin, easily eroded layer. This is then cured with a clear protective layer of polymer to give the surface finish and colour maximum longevity.
The ColourFusion™ process has undergone years of research and testing in the Group's state-of-the-art laboratories and exceeds their exacting standards. Although it is hard to quantify the expected lifetime of any finish since it varies greatly with location, it has been confirmed that tiles created using this new process will retain their intended appearance for much longer in the same environment than the equivalent tile finish produced without the ColourFusion process. A Landmark Double Roman roof retains its appeal for longer meaning that the benefits of machine-made performance, control and cost have never looked so attractive for so long.
Landmark Double Roman conform to BS EN 490: 2011 Concrete roofing tiles and fittings for roof covering and wall cladding - Product Specifications.
Landmark Double Roman has been rigorously tested in the Group wind tunnel where combinations of high wind and driving rain are used to determine the tiles performance with respect to wind loading and weathertightness. Tiles will meet the requirements of BS 5534: 2014 Code of practice for slating and tiling (including shingles), providing Redland's fixing recommendations are complied with.

FixMaster is a guaranteed tile and batten fixing specification service tailored to individual roof designs. It's Redland's high technology solution to incorrect fixing providing the most cost-effective specification to comply with British Standards.
As no two roofs are the same, FixMaster takes into account all variable factors including roof geometry, location and products used. A full assessment is made of any nearby tall structures, natural topographical features or, in the case of airports in the locality, pressures generated by aircraft trailing wake vortices.
Methods to obtain a FixMaster are:
