What do dome rooflights in Dumbarton involve?
Our dome rooflights service in Dumbarton covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. In Dumbarton, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Dumbarton is around 21 km from Glasgow, and we survey and fit throughout that part of Glasgow and Dunbartonshire, including the G82 district.
Specification options
- Fixed or hinged with vent
- Fall-through protection mesh
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic
- Fixed, hinged or vented options
- Quick replacement on existing upstands
Before you order: points to check
- Upstand condition decides whether you replace dome only or the whole unit
- Old domes may be fragile — treat as fragile until checked
Building control and safety duties in Dumbarton
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. Product data for building control is supplied with every quote.
For non-domestic buildings in Scotland, the non-domestic Technical Handbook (section 6) sets the energy standards for rooflights; we supply the manufacturer's data for the building warrant. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can domes open?
Hinged and vented domes are available, manual or electric.
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.
Do I need to be at home for the survey in Dumbarton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
