Commercial rooflight installation in Bangor

Glass is heavy, and bigger units get heavy fast. Fitting a commercial rooflight in Bangor means planning how it travels from the delivery vehicle to the roof without chipping an edge or straining a back. Smaller units go up by hand with two fitters. Larger ones may need a hoist, a scaffold loading bay or a crane, and we tell you at quote stage if that applies. Once it is up, the fitting follows the maker's sequence: seat, fix, seal, finish. We take on work like this across County Down.

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.

Covering BT20 and neighbouring districts

Covering Bangor means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in BT20, BT19 and BT21, and are happy to quote further out in Newtownards and Carrickfergus. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.

What the job includes

  • Roof survey of every unit, kerb and the fragile areas around them
  • Access, edge protection and fragile-roof covers planned before work starts
  • Phasing agreed so occupied areas stay dry and usable
  • Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
  • Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.

From arrival to clean-up

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a commercial rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning, building control and Bangor

Non-domestic rooflight work in Northern Ireland needs building control for new openings, glazing that meets the Technical Booklet energy limits, and fire checks near boundaries. Planning depends on the building and location. We set out what applies before quoting.

Getting a price from photos

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 BT20 and we will come back with a quote or a survey date.

Common questions in Bangor

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.

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.

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.
