Fit-only rooflight installation in Southampton

Builders and extension firms in Southampton often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around SO14 and the neighbouring districts are welcome.

Where our fitters travel

Looking at a property near Southampton but not quite in it? We work across SO14, SO15 and SO17 and outwards to Hythe, Totton and Hedge End. 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 Southampton.

Fit-only or supply and fit

If you have bought a rooflight yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the upstand height above the finished roof. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

What the job includes

  • Upstand height, level and fall checked, and squareness confirmed across the diagonals
  • Internal reveal trimmed or lined, with the protective film removed at the end
  • Unit bedded on the sealant or tape the maker specifies, then screw-fixed
  • Access and lifting — We check how the unit gets from your drive to the roof.
  • Delivery damage and missing parts — We ask you to open the delivery and check it as soon as it arrives, not on fitting day.

From arrival to clean-up

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A rooflight goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take half a day to a day.

Planning and building rules in England

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

What to send for a quick quote

A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, SO14 or a neighbouring district.

Common questions in Southampton

Will my new rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.

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 fit the rooflight I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
