Rooflight installers in Brentwood

Rooflight fitting in Brentwood, Essex, covers more ground than most people expect. Some jobs are fit-only: you have bought a unit and need it installed properly. Some are replacements for old domes and misted glass. Others mean cutting a new opening into a flat or pitched roof, trimming joists or rafters, and building an upstand. Then there are roof lanterns, pitched roof windows, sun tunnels and access hatches, plus trade work for builders and roofers. Each service has its own page below, with guide prices and what the job involves.

Where rooflight jobs go wrong

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.

Is your Brentwood address covered?

Covering Brentwood properly means covering the whole of it, house or business unit, across CM14, CM13 and CM15. Beyond the town, we take on jobs in Billericay (5 miles) and Hornchurch (6 miles) as standard. Each one gets the same survey or photo-based pricing, the same written quote, and the same fitting standard.

Planning and building control

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Questions about rooflight fitting in Brentwood

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.

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.

How long does fitting take?

Fitting a rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
