Frameless rooflight installation in Castlereagh

Builders and extension firms in Castlereagh 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 BT6 and the neighbouring districts are welcome.

Fitting across Castlereagh and nearby

Looking at a property near Castlereagh but not quite in it? We work across BT6, BT5 and BT7 and outwards to Belfast, Newtownabbey and Lisburn. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Castlereagh.

Your frameless rooflights or ours

There are two ways to do this. Supply and fit means we source a frameless rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What we do on the day

  • Fall set in the upstand so rain clears the oversailing glass edge
  • Glass bedded on the specified tape or sealant and fixed through the concealed frame
  • Upstand built to the maker's drawing within its stated tolerance
  • How the reveal will look — We agree the finish at the glass edge before building anything.
  • Laminated inner pane — We confirm the inner pane is laminated or otherwise suited to being overhead.

What happens on the day

Where a job takes one day, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a frameless rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Regulations for Castlereagh properties

For a home in Northern Ireland, check planning first: rooflights are excluded from permitted development in conservation areas and within the curtilage of listed buildings, and elsewhere must keep 0.5 m clear of the ridge, eaves and verges. Then building control: a new opening alters the roof structure, so expect a building control application and confirm with your council, and the glazing must achieve WER Band C or 1.6 W/m²K. We check both for your address before quoting.

Details that speed up your quote

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as BT6.

Common questions in Castlereagh

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

Do you cover Castlereagh?

Yes. Fitters travel to addresses in Castlereagh and the surrounding districts, including BT6. 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.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.
