Conservation rooflight installation in Eltham

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Eltham 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 Eltham, the SE9 district and the rest of Greater London.

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.

Is your address covered?

Eltham and the districts around it, SE9, SE12 and SE3, all sit inside our working area. So does the ground between Eltham and Blackheath (2 miles), and on towards Chislehurst (2 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

What we check on a supplied unit

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

Included in the work

  • Flashings in lead or a matching kit, dressed to the covering
  • Slates or tiles lifted carefully and kept for reuse where possible
  • Position checked against any consent drawings or council conditions
  • Conservation area rules by nation — We check the permitted development position for your nation before the rooflight is ordered.
  • Energy and old roofs — We make sure the rooflight meets current energy rules while suiting an older roof build-up.

A typical installation day

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A conservation rooflight goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one day.

Do you need permission in Eltham?

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.

Before you get in touch

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 SE9, and we can price it.

Common questions in Eltham

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