Rooflight upstands & kerbs in Clevedon

Building an upstand in Clevedon 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.

Covering BS21 and neighbouring districts

Jobs across BS21, BS49 and BS48 are part of our normal cover for Clevedon. 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 Nailsea and Portishead are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Included in the work

  • Diagonals measured so the kerb is square before anything sits on it
  • Fall built into the kerb where the rooflight needs one
  • Kerb sized from the maker's drawing, internal and external dimensions both checked
  • 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.

From arrival to clean-up

Building an upstand starts with the rooflight's own drawing: its kerb size, height above the finished roof and fall. The team sets the timber out to those figures, checks the diagonals, insulates the outer faces and dresses the membrane up and over. If the rooflight is going on the same day, it is fitted next; if not, the kerb is protected until it does.

Do you need permission in Clevedon?

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

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, BS21 or nearby, confirms travel.

Common questions in Clevedon

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

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.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
