Rooflight upstands & kerbs in Reading

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 Reading 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.

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

Jobs across RG1, RG4 and RG30 are part of our normal cover for Reading. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Lower Earley and Wokingham are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

On the day, we cover

  • Insulation fitted to the upstand faces to limit heat loss
  • Roof membrane turned up, bonded and finished at the kerb top
  • Fall built into the kerb where the rooflight needs one
  • Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
  • 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.

From arrival to clean-up

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.

Regulations for Reading properties

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

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 RG1 and we will come back with a quote or a survey date.

Common questions in Reading

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.

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 cover Reading?

Yes. Fitters travel to addresses in Reading and the surrounding districts, including RG1. 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.
