Rooflight installers in Chelmsford

Maybe the extension is nearly finished and the rooflight is still in its crate. Maybe the old dome on the kitchen roof has started to drip. Maybe you want daylight on a dark landing and wonder whether the roof can take a new opening. These are the kinds of job we take on in Chelmsford and across Essex: fit-only, replacement, new openings, roof lanterns and pitched roof windows. Builders and roofers can also bring us in for the rooflight part of a larger project, with the scope and price agreed in writing.

Specialist fitting or a general builder

Large glass units are heavy, awkward and expensive to replace if dropped. Getting one onto a roof may need a hoist, a crane or a planned lift from a scaffold. Fitting it means setting it level on packers, without twisting the frame, while the weather holds. A general builder may do this a few times a year. A rooflight fitting team plans the lift, the equipment and the sequence before the day. That lowers the risk to the unit and to the people lifting it.

Fitting in Chelmsford and beyond

Postcodes CM1, CM2 and CM3 are the core of our Chelmsford coverage, but they are not the boundary. Addresses in Billericay, Witham and Maldon are handled in just the same way, with fitters travelling to each one and travel costs built into the quote before you agree to anything. If you are unsure which side of a boundary you fall on, the full postcode settles it.

Do you need permission in Chelmsford?

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.

Questions about rooflight fitting in Chelmsford

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 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.

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.

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
