Flat rooflight installation in Southampton

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Southampton is planned around the forecast rather than pinned to a date regardless of rain. The opening is kept covered whenever it is exposed, and a roof is not left open overnight without a proper temporary seal. That approach applies to every flat rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Southampton, the SO14 district and the rest of Hampshire.

Guide ranges for supply & fit. 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.

Is your address covered?

Fitters travel to the job, so the address is what counts. In Southampton that means postcode districts SO14, SO15 and SO17, and the same teams can just as easily take on work in Hythe, about 3 miles away, or Totton at roughly 4 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

What we check on a supplied unit

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

On the day, we cover

  • Fall confirmed so rain runs off the glass rather than sitting on it
  • Reveal lined and trimmed inside, with the glass left clean
  • Product paperwork handed over and warranty registration explained
  • Solar gain on south-facing roofs — We ask which way the roof faces and how the room is used before suggesting glass.
  • Ceiling and reveal depth — We measure the depth from the kerb top to the ceiling to plan the reveal.

From arrival to clean-up

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a flat rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one day.

Planning, building control and Southampton

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Before you get in touch

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around SO14 and we will come back with a quote or a survey date.

Common questions in Southampton

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

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.

Got a unit waiting to go in, or need one sourced? Either way, start with your Southampton address and a couple of photos.
