Frameless rooflight installation in Lewisham

If the frameless 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 frameless rooflight installation in Lewisham and nearby, alongside new openings and fit-only work. Postcode SE13 and its neighbours are all within our cover.

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.

Where our fitters travel

Jobs across SE13, SE4 and SE10 are part of our normal cover for Lewisham. 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 Blackheath and Brockley 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 frameless 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 upstand height above the finished roof. 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 we do on the day

  • Fall set in the upstand so rain clears the oversailing glass edge
  • Roof covering turned up and finished under the glass overhang
  • Lifting gear arranged for heavy single panes where two people cannot safely carry
  • Glass weight and access — We plan the lift for a frameless pane before the delivery is booked.
  • Drainage at the overhang — We check how water leaves the glass where it oversails the kerb.

From arrival to clean-up

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 frameless 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.

Do you need permission in Lewisham?

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

What to send for a quick quote

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around SE13. That is enough for a first price.

Common questions in Lewisham

How long does fitting take?

Fitting a frameless rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

What if my roof opening is the wrong size for the frameless 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.

Do you cover Lewisham?

Yes. Fitters travel to addresses in Lewisham and the surrounding districts, including SE13. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
