Flat rooflights in Exmouth: what is involved?
We handle flat rooflights across Devon, including Exmouth. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
From Exmouth to Exeter, Newton Abbot and Torquay, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Solar-control or self-cleaning outer pane
- Rain sensor if paired with an opening unit
- Integral or fitted blinds
- Insulated kerb or timber upstand built to suit
- Double or triple glazing
- Slim sightlines from inside — mostly glass, little frame
- Even, top-down daylight across the whole room
Before you order: points to check
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Planning and building rules for Exmouth
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Flat rooflights in Exmouth: questions
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.
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.
Will I need planning permission in Exmouth?
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.
Do I need to be at home for the survey in Exmouth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
