Insulated upstand

Bigger kerbs or where joists need trimming first
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.
Where our fitters travel
If you also own a property or a business unit in Rhondda, Merthyr Tydfil or Tonypandy, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and CF44, CF48 and CF43 sit comfortably within that pattern.
What the job includes
- Treated timber frame fixed down to the deck and joists
- Kerb sized from the maker's drawing, internal and external dimensions both checked
- Insulation fitted to the upstand faces to limit heat loss
- 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.
- Energy limit for site-built kerbs — We insulate upstands to meet the limit for site-built upstands, which is 0.35 W/m²K in England and Wales.
Fitting your rooflight upstand, step by step
The fitters measure twice before cutting: the opening, the rooflight's kerb size and the finished roof level. The kerb is built, packed level or to the maker's fall, insulated and weathered into the roof covering. You are left with an upstand ready for the rooflight, and a note of the sizes it was built to.
Regulations for Aberdare properties
Welsh rules differ from England's in one important way: rooflights lose permitted development rights in conservation areas, National Parks, AONBs and World Heritage Sites. Elsewhere on a house, a rooflight that projects no more than 150 mm and stays below the highest part of the roof is usually fine. Building regulations still apply to new openings, replacements we fit go through a building notice because we are not scheme-registered, and the energy limit for rooflights is 2.2 W/m²K. A new Welsh Approved Document L takes effect on 4 March 2027.
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 CF44 and we will come back with a quote or a survey date.
Common questions in Aberdare
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 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 you cover Aberdare?
Yes. Fitters travel to addresses in Aberdare and the surrounding districts, including CF44. 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 CF44 postcode, and we will put together a written quote for the job.
