Conservation rooflight installation in Larne

Our guide price for conservation rooflight installation starts from £1,145, and the real figure for your roof in Larne depends on a handful of things: the size and type of conservation rooflight, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of County Antrim.

Fitting across Larne and nearby

Looking at a property near Larne but not quite in it? We work across BT40, BT38 and BT39 and outwards to Carrickfergus, Newtownabbey and Bangor. 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 Larne.

Fit-only or supply and fit

There are two ways to do this. Supply and fit means we source a conservation 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 the job includes

  • Rafters trimmed with timbers that suit the existing roof
  • Slates or tiles lifted carefully and kept for reuse where possible
  • Inside lining fitted to suit the room's ceiling or exposed rafters
  • Glazing bar and frame detail — We check whether the council has asked for particular details, such as a central glazing bar or a dark frame colour.
  • Conservation area rules by nation — We check the permitted development position for your nation before the rooflight is ordered.

Fitting your conservation rooflight, step by step

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a conservation rooflight: one day, weather permitting.

Planning, building control and Larne

Northern Ireland's building regulations set a minimum of WER Band C or 1.6 W/m²K for rooflights and roof windows in existing homes, assessed under Technical Booklet F1. New openings involve trimming the roof structure, so expect a building control application. Many house rooflights don't need planning permission, but conservation areas and listed buildings are excluded, and side windows near a boundary have obscure-glazing rules. We confirm what applies.

What to send for a quick quote

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 BT40, and we can price it.

Common questions in Larne

Do you cover Larne?

Yes. Fitters travel to addresses in Larne and the surrounding districts, including BT40. 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.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

Will my new conservation 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.

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