Trade rooflight fitting in Lewes

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any rooflight in Lewes, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

Where our fitters travel

Looking at a property near Lewes but not quite in it? We work across BN7, BN8 and BN10 and outwards to Rottingdean, Peacehaven and Brighton. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Lewes.

Included in the work

  • A short note of anything we found that needs your attention
  • Upstands built by us where you would rather not
  • Flat rooflights fitted, sealed and trimmed on your kerbs
  • Upstand ready and to size — We ask for the upstands to be built to the maker's drawing before we arrive.
  • Deliveries and damage — We check delivered units against the schedule before fitting.

Fitting your rooflight, step by step

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes half a day to a day per unit.

Regulations for Lewes properties

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.

What to send for a quick 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 BN7 and we will come back with a quote or a survey date.

Common questions in Lewes

Who deals with building control on trade jobs?

On new-build and extension work the rooflights usually sit within your approval or warrant. On replacements in homes in England and Wales we agree up front who notifies building control; we are not registered with a competent person scheme, so we cannot self-certify.

Will my new rooflight 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.

Do you cover Lewes?

Yes. Fitters travel to addresses in Lewes and the surrounding districts, including BN7. 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.

For trade fitting around BN7, send the unit spec and site details for a written price.
