Flat rooflight installation in Thornton-Cleveleys

Flat rooflight installation in Thornton-Cleveleys comes down to what happens around the glass. A good unit sat on a poor upstand, or with the membrane or flashing cut short at the corners, will still let water in. We fit each flat rooflight to the maker's instructions for fixings, packers and sealant, for homes and businesses across Thornton-Cleveleys and the rest of Lancashire. That covers supply and fit, fit-only for a unit you already own, and swapping out a tired one. Every job starts with a written quote, so the price and scope are clear before anyone climbs a ladder.

Fitting across Thornton-Cleveleys and nearby

If you also own a property or a business unit in Poulton-le-Fylde, Fleetwood or Blackpool, 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 FY5, FY6 and FY2 sit comfortably within that pattern.

Fit-only or supply and fit

There are two ways to do this. Supply and fit means we source a flat rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What we do on the day

  • Product paperwork handed over and warranty registration explained
  • Fall confirmed so rain runs off the glass rather than sitting on it
  • Upstand checked or built to the maker's internal and external sizes
  • Solar gain on south-facing roofs — We ask which way the roof faces and how the room is used before suggesting glass.
  • Ceiling and reveal depth — We measure the depth from the kerb top to the ceiling to plan the reveal.

From arrival to clean-up

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 flat 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 Thornton-Cleveleys 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.

What to send for a quick quote

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around FY5 and we will come back with a quote or a survey date.

Common questions in Thornton-Cleveleys

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.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

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.
