How we approach flat rooflights in Woking
Flat rooflights in Woking means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the GU22 district and the rest of Surrey, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Woking, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
We cover all of Woking and the GU22 district, and nearby Guildford and Egham.
What you can choose
- Double or triple glazing
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- Square, rectangular or long-format sizes
- Integral or fitted blinds
- Fixed units are simple, quiet and low-maintenance
- Double or triple glazed with a warm-edge spacer
Before you order: points to check
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- The roof membrane must be dressed up the upstand before the unit goes on
Planning, building control and Woking
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.

Common questions
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Is the survey in Woking free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
