Roof tiles - developed by Decra
It is the unique multi-layered coating that makes Decra roof tiles so light, durable and effective. While Decra tiles are around 85% lighter than traditional tiles, our system provides better weather resistance than concrete, clay, slate or plastic roof tiles.
The innovative way Decra roof tiles are produced ensures they provide exceptional long-term stability.

Composition of typical Decra tiles
Each standard roof tile from Decra consists of eight layers, designed to provide unrivalled weather protection.
At the centre is the steel core, which is then covered in zinc aluminium. A chromate conversion layer is then put in place, followed by an epoxy coating. The topside of the tile is then covered with an acrylic resin, the stone granular coating and a final clear acrylic overglaze.
A polyester coating is applied to the underside of each roof tile. This provides further protection against wind-driven salt spray. This makes Decra the ideal choice for developments in coastal locations.
The Decra Elegance range
For an added touch of luxury, choose Decra Elegance roof tiles for your roofing project. Also created using a unique multi-layered system, these attractive tiles will enhance any property.
As with the Classic tile, the core is made up of aluminium zinc galvanised steel, typically 0.43mm thick. This is then covered in a chromate conversion layer and an epoxy coating, which helps protect the tile from the elements. A powder coating is applied to the top of the tile, while the underside is covered with an epoxy/polyester coating.
At Decra, we use high-performance materials for each of our roof tiles, which is why we are confident enough to give you a unique 30-year weather security guarantee.
