Rooflight replacement in Glasgow

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Glasgow 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 replacement rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Glasgow, the G2 district and the rest of Glasgow & Dunbartonshire.

Guide ranges for supply & fit; building control notice fee extra in England and Wales. 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 warrant fees, where a job needs them, are shown as their own line.

Covering G2 and neighbouring districts

Covering Glasgow means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in G2, G4 and G1, and are happy to quote further out in Rutherglen and Bishopbriggs. 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.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a replacement 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.

On the day, we cover

  • Old rooflight or dome unscrewed, lifted out and taken away for disposal
  • New unit bedded, fixed and sealed exactly as its maker shows
  • Roof membrane repaired and turned up where it meets the kerb
  • Is the kerb worth keeping? — We decide whether the existing kerb can stay only after checking it for rot, height and squareness.
  • Inside finishes — We check the condition of the plaster and trim around the opening from inside.

How a fitting day runs

Where a job takes one day, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a replacement rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Regulations for Glasgow properties

In Scotland a new rooflight needs a building warrant before work starts. A like-for-like replacement including the frame is exempt from a warrant but must meet current standards, so the glazing has to reach 1.6 W/m²K or better. For planning, rooflights on houses outside conservation areas can often go ahead under permitted development, but it is worth confirming with the planning authority.

Before you get in touch

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in G2, and we can price it.

Common questions in Glasgow

Do you cover Glasgow?

Yes. Fitters travel to addresses in Glasgow and the surrounding districts, including G2. 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.

Does a rooflight need a building warrant?

In Scotland a new rooflight needs a building warrant from the council before work starts. Replacing a rooflight complete with its frame doesn't need a warrant, but the new unit must meet the building standards in full, including 1.6 W/m²K. We confirm which applies to your job before you commit.

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.
