Pitched roof window installation in Hartley

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Hartley 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 pitched roof window we install, from a new opening to a straight swap or a fit-only job. We cover Hartley, the DA3 district and the rest of Kent.

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.

Areas around Hartley we cover

Fitters travel to the job, so the address is what counts. In Hartley that means postcode districts DA3, DA13 and DA4, and the same teams can just as easily take on work in Longfield, about 1 mile away, or Swanscombe at roughly 4 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Your pitched roof windows 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 pitched roof window 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.

What we do on the day

  • Insulation collar and vapour layer fitted to stop a cold edge
  • Window frame fixed on its brackets, square and at the right height
  • Tiles or slates cut and refitted neatly around the flashing
  • Flashing to suit the roof — We match the flashing kit to your roof covering before ordering.
  • Scaffold or not — We look at the roof height and the window position to see whether scaffolding is needed.

Fitting your pitched roof window, 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 pitched roof window 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.

Do you need permission in Hartley?

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.

Help us quote accurately

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, DA3 or nearby, confirms travel.

Common questions in Hartley

Do I need planning permission for a rooflight in Hartley?

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.

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

Will my new pitched roof window 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.
