Rooflight replacement in Hampton

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Hampton is planned around the forecast rather than pinned to a date regardless of rain. The opening is kept covered whenever it is exposed, and a roof is not left open overnight without a proper temporary seal. That approach applies to every replacement rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Hampton, the TW12 district and the rest of Greater London.

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.

Covering TW12 and neighbouring districts

Looking at a property near Hampton but not quite in it? We work across TW12, TW11 and TW13 and outwards to West Molesey, East Molesey and Hanworth. 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 Hampton.

Fit-only or supply and fit

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a replacement rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

Included in the work

  • Building notice given to the council in England and Wales, with its fee on the quote
  • Packers, an adaptor or a new insulated upstand where the old kerb falls short
  • 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.
  • Leaks that are not the rooflight — We look at the roof around the unit before blaming the rooflight.

Fitting your replacement rooflight, step by step

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a replacement rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Regulations for Hampton properties

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.

Getting a price from photos

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 TW12. That is enough for a first price.

Common questions in Hampton

Do you cover Hampton?

Yes. Fitters travel to addresses in Hampton and the surrounding districts, including TW12. 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 replacement 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.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
