Rooflight upstands & kerbs in Rhondda

A kerb that is a few millimetres out of square, or a little too low once the roof covering goes on, can stop a rooflight sealing properly. That is why upstand work in Rhondda starts with measuring the opening, the roof build-up and the unit's kerb size together. The upstand is then built from treated timber, insulated and weathered into the membrane, felt or fibreglass. You get a written quote first and a note of the sizes it was built to.

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.

Fitting across Rhondda and nearby

Rhondda and the districts around it, CF43, CF41 and CF40, all sit inside our working area. So does the ground between Rhondda and Tonypandy (3 miles), and on towards Aberdare (4 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.

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
  • Roof membrane turned up, bonded and finished at the kerb top
  • Size tolerance on the kerb — We build kerbs to a tight tolerance because rooflight glass is made to order and cannot be trimmed on site.
  • Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.

A typical installation day

On the day, the fitters check the opening and the roof deck around it, then cut and fix treated timber to the maker's kerb size, square and level, with any fall the rooflight needs built in. Insulation goes on the faces that need it, and the roof membrane is turned up and dressed so the kerb is weathertight before anyone leaves. Most upstand jobs take half a day to a day.

Planning and building rules in Wales

Wales sets energy limits of 2.2 W/m²K for rooflights and 1.4 W/m²K for roof windows, and new rooflight openings generally need building regulations approval. Replacement units are controlled fittings; we are not registered with a competent person scheme, so ours are covered by a building notice to the council. Planning permission is needed for rooflights in conservation areas, National Parks, AONBs and World Heritage Sites. We check which applies and include the fee in your quote.

Details that speed up your 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 CF43 and we will come back with a quote or a survey date.

Common questions in Rhondda

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.

Do I need planning permission for a rooflight in Rhondda?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in Wales. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Does a rooflight need building regulations approval?

In Wales a new opening generally needs building regulations approval. A replacement must be self-certified by a scheme-registered installer or covered by a building notice. We are not registered with a scheme, so replacements we fit go through a building notice, and the council's fee is shown on your quote.
