Ridge & pitched glass roofs in Isleworth: what is involved?
For Isleworth 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Ridge & pitched glass roofs suit side returns, links and long extensions.
Isleworth sits about 1 km from Hounslow and 3 km from Richmond, and we cover the whole TW7 postcode district and the roads in between.
What you can choose
- Solar-control, self-cleaning or tinted glass
- Aluminium systems in standard and RAL colours
- Dual-pitch or mono-pitch
- Opening vents and electric actuators
- Fixed or retractable shading
- Works with exposed brick and period detail
- Opening vents available
Things we check at survey
- Overheating is a real risk on south-facing glass roofs
- Large glass roofs affect the energy calculation for the extension
Planning, building control and Isleworth
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Questions about ridge & pitched glass roofs in Isleworth
Is a glass roof too hot for a kitchen?
Without care, it can be. Solar-control glass, an opening vent at the top and a blind make a south-facing glass roof comfortable.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
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 I need planning permission in Isleworth?
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.
