How we approach ridge & pitched glass roofs in Twickenham
Ridge & pitched glass roofs in Twickenham means dual-pitch glazed roofs for side returns, links and long extensions. We cover the TW1 district and the rest of Greater London, with a survey before any price is fixed.
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. Think of ridge & pitched glass roofs for side returns, links and long extensions.
We work across Greater London, including Twickenham, and in neighbouring towns such as Richmond and Kingston upon Thames. Access, parking and how the glass reaches the roof are all checked at the survey.

- Dual-pitch or mono-pitch
- Opening vents and electric actuators
- Integrated gutters and box gutters
- Solar-control, self-cleaning or tinted glass
- Aluminium systems in standard and RAL colours

Planning, building control and Twickenham
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. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.
