Sliding rooflight installation in Egham

Builders and extension firms in Egham 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 sliding 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 TW20 and the neighbouring districts are welcome.

Areas around Egham we cover

Jobs across TW20, TW18 and GU25 are part of our normal cover for Egham. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Staines and Chertsey are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Your sliding rooflights or ours

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 sliding 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.

On the day, we cover

  • Frame fixed and weathered with the membrane dressed up the kerb
  • Cable routed to the motor, ready for the electrician's final connection, quoted as a separate line
  • Full open and close cycle checked before handover
  • Weight and lifting — We plan the lift for a sliding rooflight before it is ordered.
  • Power and safety stops — We confirm the power supply and the safety features before fitting day.

Fitting your sliding rooflight, step by step

Where a job takes one to two days, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a sliding rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

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.

What to send for a quick quote

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 TW20. That is enough for a first price.

Common questions in Egham

Will my new sliding 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.

Do you cover Egham?

Yes. Fitters travel to addresses in Egham and the surrounding districts, including TW20. 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 sliding 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.
