New rooflight in an existing roof in Whitstable

Builders and extension firms in Whitstable 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 new 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 CT5 and the neighbouring districts are welcome.

Guide ranges for supply & fit, including structure and making good; building control or warrant fees extra. 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 Whitstable

If you also own a property or a business unit in Herne Bay, Canterbury or Faversham, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and CT5, CT6 and CT2 sit comfortably within that pattern.

Fit-only or supply and fit

Your unit or ours, the fitting standard is the same. For supply and fit we choose a new 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 the job includes

  • Joists or rafters trimmed with new timbers to carry the load around
  • Opening marked out, covering stripped back and the deck cut cleanly
  • Survey of joist direction, roof build-up, ceiling void and access
  • Warm or cold roof build-up — We find out whether the roof is insulated above or between the joists before designing the upstand.
  • Which way the joists run — We check the direction and size of the joists before fixing the rooflight's position.

What happens on the 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 new 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 two to three days.

Planning, building control and Whitstable

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

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 CT5.

Common questions in Whitstable

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.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

Do I need planning permission for a rooflight in Whitstable?

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.
