What do ridge & pitched glass roofs in New Malden involve?
Our ridge & pitched glass roofs service in New Malden covers dual-pitch glazed roofs for side returns, links and long extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
New Malden is around 15 km from central London, and we survey and fit throughout that part of Greater London, including the KT3 district.

Planning and building rules for New Malden
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.
