Flat rooflights in Redland: what is involved?
Thinking about flat rooflights in Redland? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Think of flat rooflights for kitchen extensions, side returns and flat-roofed back rooms.
Redland sits about 2 km from Clifton and 2 km from Bristol, and we cover the whole BS6 postcode district and the roads in between.
Choices for your Redland project
- Frame colours: anthracite, black, white or RAL
- Plastered or lined internal reveal
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Double or triple glazing
- Even, top-down daylight across the whole room
- Double or triple glazed with a warm-edge spacer
What to check first
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Consents for flat rooflights in Redland
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. 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.

Questions about flat rooflights in Redland
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
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.
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 work alongside my builder in Redland?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Redland?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
