Dome rooflights for Castle Douglas: the essentials
For Castle Douglas homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. In Castle Douglas, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Castle Douglas is around 25 km from Dumfries, and we survey and fit throughout that part of Dumfries and Galloway, including the DG7 district.
What you can choose
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fixed or hinged with vent
- Fall-through protection mesh
- Quick replacement on existing upstands
- Smoke-vent versions available
Things we check at survey
- 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 Castle Douglas
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. We confirm the route for your building before ordering.
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. Fire classification of rooflight materials near boundaries is checked at specification.
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.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can domes open?
Hinged and vented domes are available, manual or electric.
How do I book a survey in Castle Douglas?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Castle Douglas?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
