Commercial rooflight installation in Carrickfergus

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for commercial rooflight installation in Carrickfergus, internal finishing is listed so you can see whether it is included or left for your decorator. That way a commercial rooflight looks right from the room below as well as from outside. We cover Carrickfergus and properties throughout County Antrim.

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?

If you also own a property or a business unit in Newtownabbey, Bangor or Larne, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and BT38, BT37 and BT36 sit comfortably within that pattern.

What we do on the day

  • Old units removed, with waste taken off site
  • Roof survey of every unit, kerb and the fragile areas around them
  • New units fitted, sealed and weathered into the roof covering
  • Fragile roofs and rooflights — We treat every rooflight and the roof around it as fragile until we have checked it.
  • Working around occupied buildings — We plan noise, dust and access around the people using the building.

What happens on the day

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a commercial rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes about a day per unit, longer on big roofs.

Regulations for Carrickfergus properties

On commercial buildings in Northern Ireland, rooflight openings and roof alterations go through building control, with energy and fire requirements for the glazing set out in the Technical Booklets. Smoke vents must be certified products with controls commissioned by a specialist. We confirm the route for your building.

Before you get in touch

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around BT38 and we will come back with a quote or a survey date.

Common questions in Carrickfergus

Does a rooflight need building control approval?

In Northern Ireland a new opening alters the roof structure, so expect a building control application; confirm the position with your council, including for replacements. The new rooflight must meet WER Band C or 1.6 W/m²K. We confirm what applies before you commit.

Who is responsible for the smoke-control system?

The building's responsible person, duty holder or managing agent, depending on the nation, is responsible for keeping fire safety systems working. Our part is the rooflight and roof work; the controls, detection and commissioning are handled by a smoke-control specialist, and the quote says who does what.

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
