New rooflight in an existing roof in Larne

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for new rooflight openings in Larne, internal finishing is listed so you can see whether it is included or left for your decorator. That way a new rooflight looks right from the room below as well as from outside. We cover Larne and properties throughout County Antrim.

Guide ranges for supply & fit, including structure and making good; building control or warrant fees extra. 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.

Fitting across Larne and nearby

Fitters travel to the job, so the address is what counts. In Larne that means postcode districts BT40, BT38 and BT39, and the same teams can just as easily take on work in Carrickfergus, about 9 miles away, or Newtownabbey at roughly 14 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Your rooflights or ours

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

Included in the work

  • Roof membrane, felt or tiles made good and dressed up the upstand
  • Joists or rafters trimmed with new timbers to carry the load around
  • Insulated upstand built square, level and to the maker's height
  • Which way the joists run — We check the direction and size of the joists before fixing the rooflight's position.
  • Upstand energy performance — We build the upstand to meet the energy limit for site-built upstands, not just to hold the rooflight up.

How a fitting day runs

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 new rooflight 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.

Regulations for Larne 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

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, BT40 or nearby, confirms travel.

Common questions in Larne

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.

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.

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.
