Rooflight upstands & kerbs in Bow

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 Bow 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 Bow

Covering Bow means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in E3, E15 and E14, and are happy to quote further out in Stratford and Limehouse. 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.

Included in the work

  • Diagonals measured so the kerb is square before anything sits on it
  • Roof membrane turned up, bonded and finished at the kerb top
  • Treated timber frame fixed down to the deck and joists
  • Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
  • 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

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 Bow properties

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.

Details that speed up your quote

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, E3 or nearby, confirms travel.

Common questions in Bow

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.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

Do you cover Bow?

Yes. Fitters travel to addresses in Bow and the surrounding districts, including E3. 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.

Ask for a quote for your Bow roof. Survey dates are offered based on fitter availability once you are happy with the price.
