Flat rooflights for Waterlooville: the essentials
For Waterlooville 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
From Waterlooville to Havant, Portsmouth and Fareham, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Rain sensor if paired with an opening unit
- Insulated kerb or timber upstand built to suit
- Square, rectangular or long-format sizes
- Double or triple glazing
- Solar-control or self-cleaning outer pane
- Slim sightlines from inside — mostly glass, little frame
- 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
Consents for flat rooflights in Waterlooville
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. 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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about flat rooflights in Waterlooville
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 a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
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.
Do I need to be at home for the survey in Waterlooville?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Waterlooville free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
