Rooflight installers in Bangor

Builders, roofers and extension companies in and around Bangor can bring us in at a single stage: the roof is decked or battened, and the rooflight needs fitting and detailing. We do that work, and we do the same for homeowners directly. Across County Down it ranges from fit-only installs and old-unit replacements to cutting new openings, setting lanterns on flat roofs and fitting windows into pitched ones. You get one written quote, one company responsible for the fitting, and a contract with S&K Property Investments and Improvement Ltd.

Why use a rooflight fitting specialist

Large glass units are heavy, awkward and expensive to replace if dropped. Getting one onto a roof may need a hoist, a crane or a planned lift from a scaffold. Fitting it means setting it level on packers, without twisting the frame, while the weather holds. A general builder may do this a few times a year. A rooflight fitting team plans the lift, the equipment and the sequence before the day. That lowers the risk to the unit and to the people lifting it.

Nearby towns we also cover

Covering Bangor properly means covering the whole of it, house or business unit, across BT20, BT19 and BT21. Beyond the town, we take on jobs in Newtownards (5 miles) and Carrickfergus (7 miles) as standard. Each one gets the same survey or photo-based pricing, the same written quote, and the same fitting standard.

Planning and building rules in Northern Ireland

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.

Questions about rooflight fitting in Bangor

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.

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.

What if my roof opening is the wrong size for the rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Will my new rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
