Programme of works
Phased replacement across a building, priced from a survey
Guide ranges for supply & fit, per unit; site set-up priced separately. 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.
Coverage in and around Coleraine
Fitters travel to the job, so the address is what counts. In Coleraine that means postcode districts BT52, BT55 and BT56, and the same teams can just as easily take on work in Ballymena, about 24 miles away, or Derry/Londonderry at roughly 27 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.
What the job includes
- Roof survey of every unit, kerb and the fragile areas around them
- Unit schedule and handover notes for the building's records
- Kerbs checked and packed, adapted or rebuilt where needed
- Fragile roofs and rooflights — We treat every rooflight and the roof around it as fragile until we have checked it.
- Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.
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 commercial 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.
Planning, building control and Coleraine
On commercial buildings in Northern Ireland, rooflight openings and roof alterations go through building control, with energy and fire requirements for the glazing set out in the Technical Booklets. Smoke vents must be certified products with controls commissioned by a specialist. We confirm the route for your building.
What to send for a quick 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
What upstand height and roof pitch does commercial rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Does a rooflight need building control approval?
In Northern Ireland a new opening alters the roof structure, so expect a building control application; confirm the position with your council, including for replacements. The new rooflight must meet WER Band C or 1.6 W/m²K. We confirm what applies before you commit.
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
