Rooflight replacement in Woking

If the replacement rooflight on your roof now is misted, discoloured, cracked or letting water in, replacing it is often simpler than people expect. The old unit comes out, we inspect the kerb or frame underneath, and we decide with you whether it can be reused or needs rebuilding. Then the new one goes in, sealed to the roof covering and finished inside. We handle this kind of rooflight replacement in Woking and nearby, alongside new openings and fit-only work. Postcode GU22 and its neighbours are all within our cover.

Guide ranges for supply & fit; building control notice fee extra in England and Wales. 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.

Is your address covered?

Fitters travel to the job, so the address is what counts. In Woking that means postcode districts GU22, GU21 and GU23, and the same teams can just as easily take on work in Chertsey, about 5 miles away, or Weybridge at roughly 6 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Buying your own, or letting us supply

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

What the job includes

  • Packers, an adaptor or a new insulated upstand where the old kerb falls short
  • New unit bedded, fixed and sealed exactly as its maker shows
  • Kerb inspected for rot, height, level and fall once the old unit is off
  • Inside finishes — We check the condition of the plaster and trim around the opening from inside.
  • Energy rules for the new unit — We make sure the replacement meets the current energy limit, not just the old unit's performance.

A typical installation day

Where a job takes one day, 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 replacement 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, building control and Woking

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, GU22 or nearby, confirms travel.

Common questions in Woking

What upstand height and roof pitch does replacement 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 I need planning permission for a rooflight in Woking?

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 if my roof opening is the wrong size for the replacement rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
