Maximise your roof's potential

When is a roof more than a roof? When it is a sustainable power station, an air-purifying centre, a natural respite in the heart of the city, or simply a place to park your car. From surfaces with enhanced structural attributes, to energy-generating solar solutions and bespoke green and blue roof coverings, to pioneering membranes that can destroy toxic pollutants in the air, BMI offers a variety of supplementary technologies designed to take your roof to the next level. 

These have been designed to seamlessly integrate with our high-performance, insulated roofing systems to provide a complete solution that will deliver long-term benefits for people, the planet and your pocket.
