What do ridge & pitched glass roofs in Dulwich involve?
For Dulwich homes and buildings we offer ridge & pitched glass roofs: dual-pitch glazed roofs for side returns, links and long extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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.
Dulwich is around 7 km from central London, and we survey and fit throughout that part of Greater London, including the SE21 district.

Before you order: points to check

Planning and building rules for Dulwich
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Common questions
Is a glass roof too hot for a kitchen?
Without care, it can be. Solar-control glass, an opening vent at the top and a blind make a south-facing glass roof comfortable.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Is the survey in Dulwich free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Dulwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
