Rooflight replacement in Andover

If the replacement rooflight on your roof now is misted, discoloured, cracked or letting water in, replacing it is often simpler than people expect. The old unit comes out, we inspect the kerb or frame underneath, and we decide with you whether it can be reused or needs rebuilding. Then the new one goes in, sealed to the roof covering and finished inside. We handle this kind of rooflight replacement in Andover and nearby, alongside new openings and fit-only work. Postcode SP10 and its neighbours are all within our cover.

Guide ranges for supply & fit; building control notice fee extra in England and Wales. 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 Andover

Fitters travel to the job, so the address is what counts. In Andover that means postcode districts SP10, SP11 and SO20, and the same teams can just as easily take on work in Winchester, about 13 miles away, or Newbury 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.

Buying your own, or letting us supply

Your unit or ours, the fitting standard is the same. For supply and fit we choose a replacement rooflight to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

What we do on the day

  • Old rooflight or dome unscrewed, lifted out and taken away for disposal
  • Internal reveal made good where the old trim or plaster was damaged
  • Roof membrane repaired and turned up where it meets the kerb
  • Is the kerb worth keeping? — We decide whether the existing kerb can stay only after checking it for rot, height and squareness.
  • Inside finishes — We check the condition of the plaster and trim around the opening from inside.

A typical installation day

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 replacement 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 one 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.

Before you get in touch

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as SP10.

Common questions in Andover

Can you fit the replacement 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.

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

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.
