Frameless rooflight installation in Lisburn

Builders and extension firms in Lisburn often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a frameless rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around BT27 and the neighbouring districts are welcome.

Guide ranges for supply & fit. 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 BT27 and neighbouring districts

Our fitters come to you. For Lisburn that covers BT27, BT28 and BT17, plus nearby Belfast and Castlereagh. We do not keep a yard or showroom in the area, and you do not need to visit one. The survey happens at your property or, for fit-only work, from the photos you send. Dates follow fitter availability, which we confirm when you accept the quote.

What we check on a supplied unit

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a frameless rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

On the day, we cover

  • Roof covering turned up and finished under the glass overhang
  • Inside reveal formed so plaster or trim meets the glass cleanly
  • Lifting gear arranged for heavy single panes where two people cannot safely carry
  • How the reveal will look — We agree the finish at the glass edge before building anything.
  • Tolerance on the upstand — We build frameless kerbs to the maker's tolerance rather than to normal carpentry accuracy.

What happens on the day

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 frameless rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning, building control and Lisburn

Northern Ireland has its own rules. Permitted development for rooflights on a house requires the unit to sit below the highest part of the roof, project no more than 15 cm where the slope faces a road, and stay at least half a metre from the ridge, eaves, party wall and verge. It doesn't apply in conservation areas or within the grounds of a listed building. For building control, structural roof alterations need an application, and rooflights must meet WER Band C or 1.6 W/m²K.

Details that speed up your quote

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, BT27 or nearby, confirms travel.

Common questions in Lisburn

What upstand height and roof pitch does frameless rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

How long does fitting take?

Fitting a frameless 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.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
