How we approach flat rooflights in Reading
Flat rooflights in Reading means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the RG1 district and the rest of Berkshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for flat rooflights include landings, bathrooms and rear extensions with flat roofs.
Reading is the main town we list in Berkshire; we also cover nearby Earley and Henley-on-Thames.
What you can choose
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- Plastered or lined internal reveal
- Double or triple glazing
- Rain sensor if paired with an opening unit
- Slim sightlines from inside — mostly glass, little frame
- Fixed units are simple, quiet and low-maintenance
Things we check at survey
- New openings in an existing roof need a structural check on joists
- The roof membrane must be dressed up the upstand before the unit goes on
Do you need permission in Reading?
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Questions about flat rooflights in Reading
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.
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.
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.
Do I need to be at home for the survey in Reading?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Reading?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
