Commercial rooflight installation in Brighton

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any commercial rooflight in Brighton, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

Phased replacement across a building, priced from a survey

Guide ranges for supply & fit, per unit; site set-up priced separately. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

Is your address covered?

Jobs across BN1, BN3 and BN2 are part of our normal cover for Brighton. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Hove and Portslade are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we do on the day

  • Kerbs checked and packed, adapted or rebuilt where needed
  • Phasing agreed so occupied areas stay dry and usable
  • Roof survey of every unit, kerb and the fragile areas around them
  • Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
  • Working around occupied buildings — We plan noise, dust and access around the people using the building.

Fitting your commercial rooflight, step by step

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a commercial rooflight: about a day per unit, longer on big roofs, weather permitting.

Planning and building rules in England

On commercial buildings in England, new rooflights and changes to roof structure go through building control, and replacements in non-dwellings also need building control involvement unless fitted by a scheme-registered installer, which we are not; load-bearing or structural glass always goes through building control. Fire rules matter near boundaries and over escape routes, and smoke vents must be certified to BS EN 12101-2. We confirm the route and the paperwork for your building before work starts.

Getting a price from photos

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, BN1 or nearby, confirms travel.

Common questions in Brighton

Do you cover Brighton?

Yes. Fitters travel to addresses in Brighton and the surrounding districts, including BN1. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

How long does fitting take?

Fitting a commercial rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

Do commercial rooflights need planning permission?

Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
