Flat rooflights for Bridport: the essentials
Our flat rooflights service in Bridport covers fixed double or triple glazed rooflights for flat roofs and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
We work across Dorset, including Bridport, and in neighbouring towns such as Dorchester and Yeovil. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Bridport project
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Frame colours: anthracite, black, white or RAL
- Double or triple glazing
- Insulated kerb or timber upstand built to suit
- Inner pane laminated for safety overhead
- Slim sightlines from inside — mostly glass, little frame
Before you order: points to check
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in Bridport
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. 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.
Read the planning permission guide before you commit to a design.

Questions about flat rooflights in Bridport
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.
Will I need planning permission in Bridport?
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.
Is the survey in Bridport free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
