How we approach rooflight upstands & kerbs in Castle Douglas
Thinking about rooflight upstands & kerbs in Castle Douglas? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we price.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. In Castle Douglas, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
We work across Dumfries and Galloway, including Castle Douglas, and in neighbouring towns such as Kirkcudbright and Dumfries. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Proprietary insulated kerbs
- Internal plaster-box linings
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Membrane dressed up and sealed
- Fixings and falls agreed with the rooflight maker
Before you order: points to check
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Membrane compatibility with the rooflight's sealants
Consents for rooflight upstands & kerbs in Castle Douglas
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. 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. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
How high should a rooflight upstand be?
High enough to meet the rooflight manufacturer's minimum above the finished roof surface — commonly 150 mm. On roofs with deep finishes, such as green roofs, it needs to be taller.
