New rooflight in an existing roof in Glasgow & Dunbartonshire

New rooflight in an existing roof across Glasgow & Dunbartonshire follows one method wherever the roof is. First a survey or, for fit-only work, your photos and measurements. Then a written quote with the scope and price fixed. Then a fitting day planned around the weather. We list 7 towns in Glasgow & Dunbartonshire on this site, each with its own page, but villages and addresses between them are covered in exactly the same way. Fitters travel to the property, so there is no need to be near any particular town.

Towns we list in Glasgow & Dunbartonshire

Fitting across Glasgow & Dunbartonshire means planning routes, access and lifting as well as the roof itself. Narrow lanes, shared driveways and town-centre parking restrictions all affect how a large unit is delivered and raised to roof level. We ask about these early so the quote reflects them. That approach is the same everywhere we work in Scotland, from single domestic jobs to multi-unit commercial sites.

Included in the work

  • Roof membrane, felt or tiles made good and dressed up the upstand
  • Insulated upstand built square, level and to the maker's height
  • Survey of joist direction, roof build-up, ceiling void and access
  • Which way the joists run — We check the direction and size of the joists before fixing the rooflight's position.
  • Upstand energy performance — We build the upstand to meet the energy limit for site-built upstands, not just to hold the rooflight up.

Rules that apply in Scotland

For Scottish homes: building warrant for new rooflight openings; no warrant for replacing a rooflight complete with its frame, provided it meets the standards, including 1.6 W/m²K; planning permission in conservation areas and listed building consent for listed properties. Outside those, permitted development usually covers house rooflights, but the planning authority has the final word, so we check before you commit.

Common questions in Glasgow & Dunbartonshire

What upstand height and roof pitch does rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

Do you cover Glasgow & Dunbartonshire?

Yes. Fitters travel to addresses in Glasgow & Dunbartonshire and the surrounding districts, including G postcodes. 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.

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.
