Commercial rooflight installation across County Down

Commercial rooflight installation in County Down

Across County Down we fit commercial rooflights for homeowners, builders, roofers and commercial clients. The trade side matters: an extension company with jobs running in several of the 4 towns we list does not want to coordinate a different fitter for each. We can take the rooflight element of every site, fitted to the maker's instructions and left ready for the next trade. Domestic customers get the same fitting standard, quoted in writing before work begins.

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.

Towns we list in County Down

Fitting across County Down means planning routes, access and lifting as well as the roof itself. Narrow lanes, shared driveways and town-centre parking restrictions all affect how a large unit is delivered and raised to roof level. We ask about these early so the quote reflects them. That approach is the same everywhere we work in Northern Ireland, from single domestic jobs to multi-unit commercial sites.

What the job includes

Unit schedule and handover notes for the building's records
Old units removed, with waste taken off site
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.
Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.

Rules that apply in Northern Ireland

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.

Common questions in County Down

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.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

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.
