What do flat rooflights in Cirencester involve?
Flat rooflights in Cirencester means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the GL7 district and the rest of Gloucestershire, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
We work across Gloucestershire, including Cirencester, and in neighbouring towns such as Stroud and Cheltenham. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Cirencester
- Frame colours: anthracite, black, white or RAL

Before you order: points to check
- 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
Planning, building control and Cirencester
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. 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 Cirencester
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 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 a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Do I need to be at home for the survey in Cirencester?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Cirencester?
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.
