What do flat rooflights in Maidstone involve?
Thinking about flat rooflights in Maidstone? 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Maidstone, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
Maidstone is the main town we list in Kent; we also cover nearby Chatham and Rochester.
Choices for your Maidstone project
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Integral or fitted blinds
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- Fixed units are simple, quiet and low-maintenance
- Pairs with an opening unit where you also need ventilation
Before you order: points to check
- New openings in an existing roof need a structural check on joists
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Do you need permission in Maidstone?
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
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.
Is the survey in Maidstone free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Maidstone?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
