Rooflight upstands & kerbs in Brent

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 Brent 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.

Covering HA0 and neighbouring districts

Covering Brent means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in HA0, HA9 and UB6, and are happy to quote further out in Wembley and Harrow. 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 the job includes

  • Diagonals measured so the kerb is square before anything sits on it
  • Height set above the finished roof to the maker's stated minimum
  • Kerb sized from the maker's drawing, internal and external dimensions both checked
  • 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.
  • Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.

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.

Regulations for Brent 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.

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, HA0 or nearby, confirms travel.

Common questions in Brent

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.

Do you cover Brent?

Yes. Fitters travel to addresses in Brent and the surrounding districts, including HA0. 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.

Do I need planning permission for a rooflight in Brent?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
