Walk-on rooflight installation in Staines

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Staines 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 walk-on rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Staines, the TW18 district and the rest of Surrey.

Guide ranges for supply & fit. 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 TW18 and neighbouring districts

Fitters travel to the job, so the address is what counts. In Staines that means postcode districts TW18, TW19 and TW20, and the same teams can just as easily take on work in Egham, about 2 miles away, or Ashford at roughly 2 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a walk-on 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.

On the day, we cover

  • Engineer's calculations and the unit's loading data checked together
  • Unit bedded and fixed so it sits level with the finished surface
  • Perimeter joints sealed and the waterproofing lapped as the maker shows
  • Weight on delivery day — We plan the delivery and lift before booking any lifting gear or extra hands.
  • Structural calculations — We need structural calculations for the glass and its support before a walk-on job goes ahead.

A typical installation day

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 walk-on 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 to two days.

Planning, building control and Staines

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.

Getting a price from photos

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in TW18, and we can price it.

Common questions in Staines

What upstand height and roof pitch does walk-on rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
