How we approach ridge & pitched glass roofs in Finchley
For Finchley 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of ridge & pitched glass roofs for terraced-house side returns that would otherwise be dark.
Finchley sits about 4 km from Muswell Hill and 5 km from Highgate, and we cover the whole N3 postcode district and the roads in between.
Specification options
- Integrated gutters and box gutters
- Opening vents and electric actuators
- Aluminium systems in standard and RAL colours
- Fixed or retractable shading
- Dual-pitch or mono-pitch
- Solar-control glass for south-facing slopes
- Opening vents available
What to check first
- Party-wall agreements may apply on terraced houses
- Junctions with existing walls need lead or flashing detail
Do you need permission in Finchley?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Ridge & pitched glass roofs in Finchley: questions
Can it have opening vents?
Yes, top-hung vents with electric actuators are common, often with a rain sensor.
Do I need a party wall agreement?
If the work affects a party wall or boundary, the Party Wall etc. Act 1996 may apply in England and Wales. We flag this at survey so you can serve notice in time.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Finchley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
