FLAT ROOFING:  Io Contracts Ltd are approved installers of High Performance Single Ply Roofing Systems which have a BBA certified life expectancy in excess of 25 years. These contemporary, highly effective waterproofing systems provide outstanding performance  and longevity and result in a clean, crisp, aesthetically pleasing finish, ideal for both flat roof refurbishment or new build. Single ply membranes are the new generation of flat roof waterproofing material, outperforming traditional felt roofs in every respect. When first introduced into the UK over 40 years ago they were used in commercial applications in the main, but their superb performance and longevity have resulted in single ply becoming the premium choice for domestic applications right across the country. The Single Ply Membranes we install are not only BBA certified but for most applications a manufacturer's warranty can also be provided.


GREEN ROOF SOUTH: Our specialist green roofing division covers both domestic and commercial projects including supply and installation, as well as advice on design, specification and performance. We provide a comprehensive range of beautiful green roofing/living roof systems all of which comply fully with FLL and GRO guidelines.
