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.
Fit-only or supply and fit
A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a sliding rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.
What the job includes
- Clear run confirmed for the glass to slide over when open
- Cable routed to the motor, ready for the electrician's final connection, quoted as a separate line
- Full open and close cycle checked before handover
- Planning for a roof terrace — We flag early whether planning may be needed for the work around the rooflight.
- What the glass slides over — We check the area the glass will cover when open before deciding where the unit goes.
From arrival to clean-up
Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a sliding rooflight: one to two days, weather permitting.
Do you need permission in Brent?
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.
Getting a price from photos
A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, HA0 or a neighbouring district.
Common questions in Brent
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 you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
What upstand height and roof pitch does sliding rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
