What could your roof do for you?

A place to relax in, a space to breathe easier, a tool to manage heat, rainfall or to generate power. A roof can be so much more than just a roof.
about flat and pitched roof solutions

Designing your roof

Whether you are refurbishing an existing roof, or building a new one, finding the right design is the first step towards creating the look and functionality you want. Flat or pitched – both options have their own attractions and possibilities, with the potential to create more than just a sheltering structure. The first consideration is the nature of the building and the aesthetic you want to achieve. For example, a 40-50° pitched roof using our beautiful clay tiles can offer the warm, traditional look that many people enjoy. Or you could go for a more streamlined, modern appearance with sleek metal tiles and a low profile with a pitch of less than 15°, allowing more headroom in the living space below without increasing the overall height of the building.  A flat roof typically offers a straightforward option for large buildings, often providing a practical space to accommodate building services and plant rooms. But this blank canvas could also become a natural habitat, an environmental asset, a means of generating energy, or simply an additional outdoor room for your home. Whatever your preference or your needs, as the only global manufacturer and supplier of both pitched and flat roofing systems, BMI can help you to find the ideal solution.
