Ridge & pitched glass roofs in Chiswick: what is involved?
Ridge & pitched glass roofs in Chiswick means dual-pitch glazed roofs for side returns, links and long extensions. We cover the W4 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Typical uses for ridge & pitched glass roofs include terraced-house side returns that would otherwise be dark.
Chiswick sits about 2 km from Hammersmith and 2 km from Acton, and we cover the whole W4 postcode district and the roads in between.

Consents for ridge & pitched glass roofs in Chiswick
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
