Conservation rooflight installation in West Molesey

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in West Molesey 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 conservation rooflight we install, from a new opening to a straight swap or a fit-only job. We cover West Molesey, the KT8 district and the rest of Surrey.

Where our fitters travel

Jobs across KT8, TW16 and KT12 are part of our normal cover for West Molesey. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Hampton and East Molesey are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we check on a supplied unit

If you have bought a conservation rooflight yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the flashing kit and the roof pitch range. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

What the job includes

  • Slates or tiles made good around the frame with tidy cuts
  • Position checked against any consent drawings or council conditions
  • Rooflight set low so it sits close to the line of the roof
  • Glazing bar and frame detail — We check whether the council has asked for particular details, such as a central glazing bar or a dark frame colour.
  • Reusing the original covering — We plan to reuse the existing slates or tiles wherever we can.

What happens on the day

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a conservation rooflight: one day, weather permitting.

Planning and building rules in England

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.

Details that speed up your 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 KT8 and we will come back with a quote or a survey date.

Common questions in West Molesey

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.

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.

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.
