Rooflight upstands & kerbs in Perth: what is involved?
Rooflight upstands & kerbs in Perth means insulated kerbs built and waterproofed to suit your rooflight. We cover the PH1 district and the rest of Perth and Kinross, with a survey before any price is fixed.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. In Perth, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
We cover all of Perth and the PH1 district, and nearby Auchterarder and Kinross.
What you can choose
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Proprietary insulated kerbs
- Timber upstands with insulation
- Raised upstands for deep green or ballasted roofs
- Insulated to avoid a cold bridge
- Built square to the rooflight size
Things we check at survey
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Insulation continuity around the upstand affects condensation
Planning and building rules for Perth
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.

Rooflight upstands & kerbs in Perth: 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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Is the survey in Perth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
