How we approach conservation rooflights in Dumbarton
We handle conservation rooflights across Glasgow and Dunbartonshire, including Dumbarton. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
Jobs in Dumbarton are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning, building control and Dumbarton
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Listed buildings need listed building consent where the work affects their character.
Scotland's Technical Handbook (section 6) asks for windows, doors and rooflights in an extension to average 1.4–1.6 W/m²K, with no single unit worse than 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
Read the planning permission guide before you commit to a design.

Some makers produce bespoke sizes to match an existing opening. We can survey and quote.
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
Can you work alongside my builder in Dumbarton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
