Roof access hatch installation in Lewes

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Lewes 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 access hatch we install, from a new opening to a straight swap or a fit-only job. We cover Lewes, the BN7 district and the rest of East Sussex.

Areas around Lewes we cover

Jobs across BN7, BN8 and BN10 are part of our normal cover for Lewes. 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 Rottingdean and Peacehaven are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Your roof access hatches or ours

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a roof access hatch on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

Included in the work

  • Opening and closing tested and the controls explained
  • Gas struts or actuator fitted and adjusted for full opening
  • Opening and upstand sized for a clear climb-through, not just daylight
  • How far the lid opens — We check how far the lid swings open and what it swings over.
  • Clear opening size — We check the hatch's clear opening rather than its outer size.

From arrival to clean-up

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 roof access hatch 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 one day.

Planning and building rules in England

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Help us quote accurately

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in BN7, and we can price it.

Common questions in Lewes

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.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.

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.
