Flat Roof Skylight Installation in Gloucester
Bright, watertight flat roof skylights installed across Gloucester — from city terraces to suburban extensions. Fixed written quotes, guaranteed workmanship.
Gloucester’s housing is a real mix — Victorian terraces in Tredworth and Barton, post-war semis in Longlevens and Tuffley, and a wave of modern flat-roofed extensions across them all. Wherever a flat roof meets a dark room, a flat roof skylight is the upgrade that changes everything. We are just a short drive down the A40 from our Cheltenham base, and we install across the city regularly.
Why a flat roof skylight suits Gloucester homes
The classic Gloucester rear extension — a kitchen-diner or family room added behind a terrace or semi — tends to sit under a flat roof and rely on a single back window for light. The result is often gloomier than it should be. An overhead skylight pours daylight straight down into the middle of the room, where windows simply cannot reach, making a real difference to how the space feels and how much you use it.
Why use a specialist
On any flat roof, the weak point is never the glass — it is the upstand, the flashing and the fall. Get those right and the unit stays bone-dry; get them wrong and it leaks at the first heavy rain off the Severn. We build the upstand to the correct height, lap the flashing into your roof covering properly, and set the fall so water clears cleanly. It is unglamorous detail done patiently, and it is exactly what keeps a flat-roof skylight watertight for years.
Options for your flat roof
- Slim-frame flush glass — a clean, modern look with the glass nearly flat to the roof.
- Fixed or opening — daylight only, or a unit that opens to ventilate a kitchen or utility.
- Large panes — a single big sheet over a dining area or island.
- Energy-efficient glazing — warm, quiet units that keep running costs down.
Building regulations & glazing notes
A flat roof skylight must meet Building Regulations — Part L for energy efficiency and Part K for safety glazing where relevant. We fit units that meet the required U-value as standard. Most installations fall under permitted development, with conservation areas — including parts of the city centre and the cathedral quarter — and listed buildings the usual exceptions, which we always check first.
