Ridge & pitched glass roofs for Greenwich: the essentials
Ridge & pitched glass roofs in Greenwich means dual-pitch glazed roofs for side returns, links and long extensions. We cover the SE10 district and the rest of Greater London, with a survey before any price is fixed.
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. In Greenwich, as anywhere, ridge & pitched glass roofs are the usual choice for terraced-house side returns that would otherwise be dark.
Greenwich sits about 2 km from Blackheath and 3 km from Lewisham, and we cover the whole SE10 postcode district and the roads in between.

Planning and building rules for Greenwich
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Ridge & pitched glass roofs in Greenwich: questions
Do I need a party wall agreement?
If the work affects a party wall or boundary, the Party Wall etc. Act 1996 may apply in England and Wales. We flag this at survey so you can serve notice in time.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
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.
Can you work alongside my builder in Greenwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Greenwich?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
