Frameless rooflight installation in Coleraine

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Coleraine is planned around the forecast rather than pinned to a date regardless of rain. The opening is kept covered whenever it is exposed, and a roof is not left open overnight without a proper temporary seal. That approach applies to every frameless rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Coleraine, the BT52 district and the rest of County Londonderry.

Coverage in and around Coleraine

Jobs across BT52, BT55 and BT56 are part of our normal cover for Coleraine. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Ballymena and Derry/Londonderry are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Your frameless rooflights or ours

Your unit or ours, the fitting standard is the same. For supply and fit we choose a frameless rooflight to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

On the day, we cover

  • Upstand built to the maker's drawing within its stated tolerance
  • Glass bedded on the specified tape or sealant and fixed through the concealed frame
  • Lifting gear arranged for heavy single panes where two people cannot safely carry
  • Tolerance on the upstand — We build frameless kerbs to the maker's tolerance rather than to normal carpentry accuracy.
  • Glass weight and access — We plan the lift for a frameless pane before the delivery is booked.

Fitting your frameless 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 frameless rooflight: one day, weather permitting.

Planning and building rules in Northern Ireland

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.

Details that speed up your quote

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around BT52 and we will come back with a quote or a survey date.

Common questions in Coleraine

Do I need planning permission for a rooflight in Coleraine?

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.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

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.
