Flat rooflights for Peterborough: the essentials
For Peterborough 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
We cover all of Peterborough and the PE1 district, and nearby Stamford and Oundle.
Choices for your Peterborough project
- Square, rectangular or long-format sizes
- Plastered or lined internal reveal
- Integral or fitted blinds
- Rain sensor if paired with an opening unit
- Solar-control or self-cleaning outer pane
- Inner pane laminated for safety overhead
- 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
- New openings in an existing roof need a structural check on joists
Planning, building control and Peterborough
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.
Read the planning permission guide before you commit to a design.

Flat rooflights in Peterborough: questions
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.
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 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.
Is the survey in Peterborough free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Peterborough?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
