What do flat rooflights in Clifton involve?
We handle flat rooflights across Bristol, including Clifton. 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Clifton, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
Clifton is around 2 km from Bristol, and we survey and fit throughout that part of Bristol, including the BS8 district.
Specification options
- Rain sensor if paired with an opening unit
- Plastered or lined internal reveal
- Frame colours: anthracite, black, white or RAL
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Even, top-down daylight across the whole room
- Slim sightlines from inside — mostly glass, little frame
Things we check at survey
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Do you need permission in Clifton?
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Is the survey in Clifton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Clifton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
