Sun tunnel installation in Carrickfergus

Cut the opening. Trim the joists or rafters. Build the upstand or fit the flashing kit. Fix the unit, seal it, finish the inside. On a new opening, that is the whole job in plain terms, and each step has to be right for the next one to work. We carry out this work in Carrickfergus and across County Antrim, either installing a unit you have bought or sourcing one for you. You get a written quote with the scope set out, and a written workmanship guarantee on the fitting with its terms on that quote.

Fitting across Carrickfergus and nearby

Fitters travel to the job, so the address is what counts. In Carrickfergus that means postcode districts BT38, BT37 and BT36, and the same teams can just as easily take on work in Newtownabbey, about 6 miles away, or Bangor at roughly 7 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Your sun tunnels or ours

There are two ways to do this. Supply and fit means we source a sun tunnel 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.

Included in the work

  • Tube insulated where it passes through a cold loft
  • Roof opening cut and the flashing fitted to tiles, slates or a flat-roof kit
  • Dome fixed and sealed on top of the flashing
  • Tube size — We match the tube size to the room and the roof.
  • Length and bends in the tube — We plan the shortest, straightest route we can between the roof and the ceiling.

From arrival to clean-up

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a sun tunnel runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Planning, building control and Carrickfergus

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.

Before you get in touch

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in BT38, and we can price it.

Common questions in Carrickfergus

Do you cover Carrickfergus?

Yes. Fitters travel to addresses in Carrickfergus and the surrounding districts, including BT38. 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.

Will my new sun tunnel 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.

Do I need planning permission for a rooflight in Carrickfergus?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in Northern Ireland. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Got a unit waiting to go in, or need one sourced? Either way, start with your Carrickfergus address and a couple of photos.
