How we approach flat rooflights in Leeds
Flat rooflights in Leeds means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the LS1 district and the rest of West Yorkshire, with a survey before any price is fixed.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. In Leeds, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
Leeds is the main town we list in West Yorkshire; we also cover nearby Morley and Pudsey.
Choices for your Leeds project
- Double or triple glazing
- Rain sensor if paired with an opening unit
- Solar-control or self-cleaning outer pane
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- Pairs with an opening unit where you also need ventilation
- Slim sightlines from inside — mostly glass, little frame
What to check first
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- The roof membrane must be dressed up the upstand before the unit goes on
Planning and building rules for Leeds
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Flat rooflights in Leeds: questions
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.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
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.
Do you fit flat rooflights in Leeds?
Yes. We survey and fit flat rooflights in Leeds and across West Yorkshire. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Leeds?
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.
