How we approach ridge & pitched glass roofs in Lewisham
Our ridge & pitched glass roofs service in Lewisham 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
We work across Greater London, including Lewisham, and in neighbouring towns such as Catford and Peckham. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Lewisham

- Fixed or retractable shading

Before you order: points to check
- Large glass roofs affect the energy calculation for the extension
- Overheating is a real risk on south-facing glass roofs
Planning, building control and Lewisham
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.
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.
