What do flat rooflights in Camborne involve?
Thinking about flat rooflights in Camborne? 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Flat rooflights suit kitchen extensions, side returns and flat-roofed back rooms.
Camborne is around 18 km from Truro, and we survey and fit throughout that part of Cornwall, including the TR14 district.
Options we can specify in Camborne
- Solar-control or self-cleaning outer pane
- Frame colours: anthracite, black, white or RAL
- Plastered or lined internal reveal
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Slim sightlines from inside — mostly glass, little frame
- Double or triple glazed with a warm-edge spacer
What to check first
- The roof membrane must be dressed up the upstand before the unit goes on
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Do you need permission in Camborne?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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