Rooflight upstands & kerbs in Royston

Guide prices

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.

Is your address covered?

Jobs across SG8, CB22 and CB2 are part of our normal cover for Royston. 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 Letchworth Garden City and Biggleswade 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

• Height set above the finished roof to the maker's stated minimum
• Fall built into the kerb where the rooflight needs one
• Diagonals measured so the kerb is square before anything sits on it
• Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.
• 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.

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 England

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.

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 SG8 and we will come back with a quote or a survey date.
