Rooflight replacement in Glasgow & Dunbartonshire

We cover 36 postcode districts across Glasgow & Dunbartonshire, and we fit replacement rooflights in all of them. The work itself does not change from one district to the next. A replacement rooflight still needs a correctly sized opening, an upstand or flashing to suit the roof, and sealing that matches the covering. What does change is access: terraced streets, long gardens, steep pitches, tight parking. We price that honestly in the written quote rather than averaging it out across every job.

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.

Towns we list in Glasgow & Dunbartonshire

Glasgow & Dunbartonshire is part of our normal coverage in Scotland. Fitting teams travel out to the property, so a town-centre terrace and a house down a farm track are treated alike, as long as a fitter can get the unit to the roof safely. Dates are offered according to fitter availability, and the cost of travel is already in your written quote.

What's included

  • Kerb inspected for rot, height, level and fall once the old unit is off
  • Internal reveal made good where the old trim or plaster was damaged
  • New unit bedded, fixed and sealed exactly as its maker shows
  • Energy rules for the new unit — We make sure the replacement meets the current energy limit, not just the old unit's performance.
  • Is the kerb worth keeping? — We decide whether the existing kerb can stay only after checking it for rot, height and squareness.

Rules that apply in Scotland

In Scotland, forming a new rooflight opening needs a building warrant from the council, because the roof is being altered. Replacing an existing rooflight complete with its frame doesn't need a warrant, but the new unit still has to meet the building standards, including the 1.6 W/m²K energy figure for windows and rooflights in alterations. Planning depends on the house and where it is: householder permitted development rights don't apply in conservation areas, and listed buildings need consent. We confirm this with you before quoting.

Common questions in Glasgow & Dunbartonshire

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.

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.
