Rooflight upstands & kerbs in Bridgend

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 Bridgend 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.

Coverage in and around Bridgend

Covering Bridgend means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in CF31, CF35 and CF32, and are happy to quote further out in Porthcawl and Maesteg. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.

What we do on the day

  • Kerb sized from the maker's drawing, internal and external dimensions both checked
  • Insulation fitted to the upstand faces to limit heat loss
  • Roof membrane turned up, bonded and finished at the kerb top
  • 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.
  • 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.

From arrival to clean-up

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.

Planning, building control and Bridgend

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.

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, CF31 or nearby, confirms travel.

Common questions in Bridgend

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.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

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.
