How we approach ridge & pitched glass roofs in Derby
Our ridge & pitched glass roofs service in Derby 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.
Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
We cover all of Derby and the DE1 district, and nearby Belper and Ilkeston.
Options we can specify in Derby
- Integrated gutters and box gutters
- Fixed or retractable shading
- Solar-control, self-cleaning or tinted glass
- Dual-pitch or mono-pitch
- Opening vents and electric actuators
- Opening vents available

What to check first
- Party-wall agreements may apply on terraced houses
- Large glass roofs affect the energy calculation for the extension
Planning, building control and Derby
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.
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.
