To create this type of loft conversion, a dormer-box type structure is added to the roof, where the walls are at a 90° angle to the floor. This allows for higher headroom, maximising the available capacity within the roof. A dormer loft conversion is versatile and will work with a variety of roof pitches and property types. It is possible to install one in many different positions: at the rear of a property, the side, the front, or on top of a flat roof.
The dormer structure is fixed to the existing roof, with a wooden beam structure and a steel frame when required. There is also the option to use blocks and brick gables, as calculated by the structural engineer. The structure is then clad with ply and breathable membranes, with a flat roof made of Rubber or GRP with a 20 year non leaking guarantee. Matching concrete or slate tiles are used to ensure the dormer blends in with the existing building. To finish, plastic or wood facias are fitted, along with gutters and downpipes. Windows and Velux rooflights can be installed as natural light solutions.
