What do ridge & pitched glass roofs in Carshalton involve?
We handle ridge & pitched glass roofs across Greater London, including Carshalton. In short: dual-pitch glazed roofs for side returns, links and long extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for ridge & pitched glass roofs include side returns, links and long extensions.
We work across Greater London, including Carshalton, and in neighbouring towns such as Wallington and Sutton. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for ridge & pitched glass roofs in Carshalton
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
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.

Questions about ridge & pitched glass roofs in Carshalton
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 it have opening vents?
Yes, top-hung vents with electric actuators are common, often with a rain sensor.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Do I need to be at home for the survey in Carshalton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Carshalton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
