Ridge & pitched glass roofs for Blackheath: the essentials
For Blackheath homes and buildings we offer ridge & pitched glass roofs: dual-pitch glazed roofs for side returns, links and long extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
Jobs in Blackheath are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Dual-pitch or mono-pitch
- Solar-control, self-cleaning or tinted glass
- Opening vents and electric actuators
- Fixed or retractable shading
- Aluminium systems in standard and RAL colours
- Maximum daylight for side returns
- Slim aluminium glazing bars
What to check first
- Party-wall agreements may apply on terraced houses
- Junctions with existing walls need lead or flashing detail
Consents for ridge & pitched glass roofs in Blackheath
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. 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.

Yes, top-hung vents with electric actuators are common, often with a rain sensor.
