New rooflight in an existing roof in Barrow-in-Furness

Already bought a new rooflight, or still deciding which one to get? Both are fine. For new rooflight openings in Barrow-in-Furness we either source a suitable unit and install it, or fit the one waiting in your garage. Fit-only jobs are usually priced from your photos and measurements, while supply-and-fit and replacement jobs get a free survey first. Whichever route you take, the opening, the upstand or flashing, and the delivery are checked before anything is fixed down. Properties in LA14 and the surrounding districts are covered on the same terms.

Guide ranges for supply & fit, including structure and making good; building control or warrant fees extra. 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.

Areas around Barrow-in-Furness we cover

Fitters travel to the job, so the address is what counts. In Barrow-in-Furness that means postcode districts LA14, LA13 and LA15, and the same teams can just as easily take on work in Heysham, about 14 miles away, or Morecambe at roughly 15 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Already bought your unit?

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a new rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

What the job includes

  • Insulated upstand built square, level and to the maker's height
  • Rooflight fitted, sealed and checked for even clearance on every side
  • Survey of joist direction, roof build-up, ceiling void and access
  • Upstand energy performance — We build the upstand to meet the energy limit for site-built upstands, not just to hold the rooflight up.
  • Warm or cold roof build-up — We find out whether the roof is insulated above or between the joists before designing the upstand.

From arrival to clean-up

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a new rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes two to three days.

Planning and building rules in England

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Help us quote accurately

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around LA14. That is enough for a first price.

Common questions in Barrow-in-Furness

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.

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.

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
