How we approach ridge & pitched glass roofs in Crawley
Thinking about ridge & pitched glass roofs in Crawley? The short answer: dual-pitch glazed roofs for side returns, links and long extensions. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
We cover all of Crawley and the RH11 district, and nearby Horley and Horsham.
Choices for your Crawley project
- Fixed or retractable shading
- Solar-control, self-cleaning or tinted glass
- Aluminium systems in standard and RAL colours
- Opening vents and electric actuators
- Integrated gutters and box gutters
- Maximum daylight for side returns
- Solar-control glass for south-facing slopes
Things we check at survey
- Party-wall agreements may apply on terraced houses
- Large glass roofs affect the energy calculation for the extension
Planning, building control and Crawley
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.
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.
Read the planning permission guide before you commit to a design.

Common questions
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
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.
How long does a ridge roof take to fit?
Typically two to four days once the walls and supports are ready, depending on length and access.
Will I need planning permission in Crawley?
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.
Is the survey in Crawley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
