Ridge & pitched glass roofs in Harrow: what is involved?
Our ridge & pitched glass roofs service in Harrow 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. Typical uses for ridge & pitched glass roofs include terraced-house side returns that would otherwise be dark.
Harrow sits about 4 km from Wembley and 4 km from Northolt, and we cover the whole HA2 postcode district and the roads in between.

Planning, building control and Harrow
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.
