Rooflight upstands & kerbs for Dumbarton: the essentials
Our rooflight upstands & kerbs service in Dumbarton covers insulated kerbs built and waterproofed to suit your rooflight. 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. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.

Do you need permission in Dumbarton?
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.

Common questions
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
How do I book a survey in Dumbarton?
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 Dumbarton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
