How we approach flat rooflights in Uxbridge
Thinking about flat rooflights in Uxbridge? 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
We work across Greater London, including Uxbridge, and in neighbouring towns such as Ruislip and Hayes. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Uxbridge
- Frame colours: anthracite, black, white or RAL

- Rain sensor if paired with an opening unit
- Inner pane laminated for safety overhead

Before you order: points to check
- 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
Planning, building control and Uxbridge
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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 Uxbridge: questions
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.
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.
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.
Will I need planning permission in Uxbridge?
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.
Do I need to be at home for the survey in Uxbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
