Towns we list in County Down
Coverage in County Down works by postcode, not by distance from an office. Give us the full postcode and we will confirm whether it is standard cover, as it is for most of Northern Ireland, or one of the few remote and island areas handled by arrangement. Either way, you get a written quote before any work is booked, with travel included in the price.
What the job includes
- Tube insulated where it passes through a cold loft
- Dome fixed and sealed on top of the flashing
- Dust cleared from the room below and the loft
- Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
- Tube size — We match the tube size to the room and the roof.
Rules that apply in Northern Ireland
In Northern Ireland, the energy standard for a new or replacement rooflight or roof window in an existing home is WER Band C or a U-value of 1.6 W/m²K, under Technical Booklet F1. Cutting a new opening alters the roof structure, so a building control application is expected; confirm with the council's building control team. Planning permitted development covers many rooflights on houses if they stay below the ridge, project no more than 15 cm on a road-facing slope and sit at least 0.5 m from the ridge, eaves and verges.
Common questions in County Down
What if my roof opening is the wrong size for the sun tunnel?
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.
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.
Do you offer trade rates for builders and roofers?
We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
