Flat rooflights for Fleet: the essentials
For Fleet homes and buildings we offer flat rooflights: fixed double or triple glazed rooflights for flat roofs and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
Fleet is around 58 km from Southampton, and we survey and fit throughout that part of Hampshire, including the GU51 district.
What you can choose
- Insulated kerb or timber upstand built to suit
- Square, rectangular or long-format sizes
- Plastered or lined internal reveal
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Fixed units are simple, quiet and low-maintenance
- Double or triple glazed with a warm-edge spacer
Things we check at survey
- New openings in an existing roof need a structural check on joists
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Do you need permission in Fleet?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Flat rooflights in Fleet: 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.
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.
Do I need to be at home for the survey in Fleet?
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 Fleet?
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.
