Rooflight upstands & kerbs in Ammanford

Building an upstand in Ammanford starts with the rooflight's own drawing, not a standard size. The kerb has to match the unit's internal dimensions, stand high enough above the finished roof for water to run off, and be level or pitched as the maker asks. We set the timber out to those figures, check the diagonals, insulate and weather it. If the rooflight is not on site yet, send us its make and model so the kerb is built for it.

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.

Areas around Ammanford we cover

If you also own a property or a business unit in Clydach, Gorseinon or Llanelli, 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 SA18, SA14 and SA15 sit comfortably within that pattern.

Included in the work

  • Treated timber frame fixed down to the deck and joists
  • Height set above the finished roof to the maker's stated minimum
  • Kerb sized from the maker's drawing, internal and external dimensions both checked
  • 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.
  • Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.

What happens on the 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, building control and Ammanford

For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.

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, SA18 or nearby, confirms travel.

Common questions in Ammanford

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 cover Ammanford?

Yes. Fitters travel to addresses in Ammanford and the surrounding districts, including SA18. 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.

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.
