Rooflight upstands & kerbs in Gelligaer

An upstand is the timber kerb a flat-roof rooflight sits on, and most fitting problems start there. Each maker sets the kerb size, the minimum height above the finished roof and whether the kerb should be level or built to a fall. We build upstands in Gelligaer to those figures for the rooflight you have chosen, insulate the faces that need it and dress the roof membrane up and over so the kerb is weathertight. Every job is quoted in writing first.

Areas around Gelligaer we cover

Looking at a property near Gelligaer but not quite in it? We work across CF82, CF81 and NP12 and outwards to Blackwood, Pontypridd and Caerphilly. 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 Gelligaer.

On the day, we cover

  • Height set above the finished roof to the maker's stated minimum
  • Diagonals measured so the kerb is square before anything sits on it
  • Insulation fitted to the upstand faces to limit heat loss
  • Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
  • 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.

Fitting your rooflight upstand, step by step

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 Gelligaer?

In Wales, a new rooflight opening generally needs building regulations approval, and a replacement needs either a scheme-registered installer's certificate or a building notice to the council. We are not registered with a scheme, so we use a building notice and show the fee on the quote. Rooflights must meet 2.2 W/m²K and roof windows 1.4 W/m²K. Planning is tighter than in England: rooflights are not permitted development in conservation areas, National Parks, Areas of Outstanding Natural Beauty or World Heritage Sites, so we check your address before quoting.

Before you get in touch

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 CF82 and we will come back with a quote or a survey date.

Common questions in Gelligaer

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.

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 cover Gelligaer?

Yes. Fitters travel to addresses in Gelligaer and the surrounding districts, including CF82. 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.

Send a few photos and your CF82 postcode, and we will put together a written quote for the job.
