Roof lantern installation in Redhill

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Redhill 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 roof lantern we install, from a new opening to a straight swap or a fit-only job. We cover Redhill, the RH1 district and the rest of Surrey.

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.

Coverage in and around Redhill

Fitters travel to the job, so the address is what counts. In Redhill that means postcode districts RH1, RH2 and KT20, and the same teams can just as easily take on work in Reigate, about 2 miles away, or Horley at roughly 5 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Fit-only or supply and fit

Your unit or ours, the fitting standard is the same. For supply and fit we choose a roof lantern to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

On the day, we cover

  • Glass lifted and laid into the frame by hand or with gear
  • Frame assembled on the kerb in the maker's set order
  • Roof membrane checked where it meets the lantern frame
  • Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
  • Following the build order — We assemble lanterns in exactly the sequence the instructions give.

Fitting your roof lantern, step by step

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a roof lantern, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Regulations for Redhill properties

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

What to send for a quick quote

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as RH1.

Common questions in Redhill

Can you fit the roof lantern I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.

Will my new roof lantern 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.

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.
