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.
Fitting across Belfast and nearby
Looking at a property near Belfast but not quite in it? We work across BT1, BT2 and BT7 and outwards to Castlereagh, Newtownabbey and Lisburn. 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 Belfast.
What the job includes
- Kerbs checked and packed, adapted or rebuilt where needed
- New units fitted, sealed and weathered into the roof covering
- Phasing agreed so occupied areas stay dry and usable
- Working around occupied buildings — We plan noise, dust and access around the people using the building.
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
Fitting your commercial 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 commercial rooflight: about a day per unit, longer on big roofs, weather permitting.
Planning and building rules in Northern Ireland
Non-domestic rooflight work in Northern Ireland needs building control for new openings, glazing that meets the Technical Booklet energy limits, and fire checks near boundaries. Planning depends on the building and location. We set out what applies before quoting.
Getting a price from photos
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, BT1 or nearby, confirms travel.
Common questions in Belfast
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.
Do you cover Belfast?
Yes. Fitters travel to addresses in Belfast and the surrounding districts, including BT1. 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.
How long does fitting take?
Fitting a commercial rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
