Rooflight upstands & kerbs in Whitehaven

Replacing an old dome or a failed rooflight often means the kerb underneath has to change too: it may be rotten, too low for the new unit or the wrong size. We strip back what is needed, build a new upstand in Whitehaven to the new unit's dimensions, insulate it and dress the roof covering up to it. Where only part of the kerb has failed, we say so and price the smaller repair. The scope is set out in a written quote before work starts.

Guide ranges for labour and materials, rooflight not included. 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 Whitehaven

Distance is rarely the deciding factor. A roof in Workington, 7 miles from Whitehaven, gets the same survey, the same written quote and the same fitting process as one in CA28, CA24 and CA25. What changes the price is the job itself: size of unit, roof type, access and lifting. Barrow-in-Furness, around 34 miles out, is treated the same way.

On the day, we cover

  • Diagonals measured so the kerb is square before anything sits on it
  • Treated timber frame fixed down to the deck and joists
  • Insulation fitted to the upstand faces to limit heat loss
  • Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.
  • Height above the finished roof — We set the upstand so it stands at least 150 mm above the finished roof, measured from the top of any ballast, paving or walkway.

What happens on the day

Building an upstand starts with the rooflight's own drawing: its kerb size, height above the finished roof and fall. The team sets the timber out to those figures, checks the diagonals, insulates the outer faces and dresses the membrane up and over. If the rooflight is going on the same day, it is fitted next; if not, the kerb is protected until it does.

Do you need permission in Whitehaven?

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.

Help us quote accurately

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, CA28 or nearby, confirms travel.

Common questions in Whitehaven

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.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
