Rooflight replacement in Epsom

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Epsom 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 Epsom, the KT18 district and the rest of Surrey.

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.

Where our fitters travel

Looking at a property near Epsom but not quite in it? We work across KT18, KT17 and KT19 and outwards to Ewell, Chessington and Banstead. 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 Epsom.

Fit-only or supply and fit

If you have bought a replacement 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.

Included in the work

  • Old rooflight or dome unscrewed, lifted out and taken away for disposal
  • 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
  • Dome to glass upgrades — We check that the opening and kerb suit a flat glass unit before quoting a dome-to-glass swap.
  • Energy rules for the new unit — We make sure the replacement meets the current energy limit, not just the old unit's performance.

Fitting your replacement rooflight, step by step

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 replacement 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 one day.

Regulations for Epsom properties

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Details that speed up your 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, KT18 or a neighbouring district.

Common questions in Epsom

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 cover Epsom?

Yes. Fitters travel to addresses in Epsom and the surrounding districts, including KT18. 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.

Do I need planning permission for a rooflight in Epsom?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
