Rooflight upstands & kerbs in Helensburgh: what is involved?
Thinking about rooflight upstands & kerbs in Helensburgh? 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.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. In Helensburgh, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
Helensburgh is the main town we list in Argyll and Bute; we also cover nearby Greenock and Gourock.
What you can choose
- Timber upstands with insulation
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Membrane dressed up and sealed
- Built square to the rooflight size
Before you order: points to check
- Insulation continuity around the upstand affects condensation
- Upstand size must match the unit within a tight tolerance
Consents for rooflight upstands & kerbs in Helensburgh
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. Listed buildings need listed building consent where the work affects their character.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Rooflight upstands & kerbs in Helensburgh: 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.
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.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can you work alongside my builder in Helensburgh?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Helensburgh free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
