How we approach flat rooflights in Yate
We handle flat rooflights across Gloucestershire, including Yate. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for flat rooflights include landings, bathrooms and rear extensions with flat roofs.
We work across Gloucestershire, including Yate, and in neighbouring towns such as Mangotsfield and Fishponds. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Rain sensor if paired with an opening unit
- Slim sightlines from inside — mostly glass, little frame
- Double or triple glazed with a warm-edge spacer
Things we check at survey
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- New openings in an existing roof need a structural check on joists
Do you need permission in Yate?
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. 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.

Flat rooflights in Yate: 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.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
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.
Will I need planning permission in Yate?
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.
Can you work alongside my builder in Yate?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
