How we approach rooflight upstands & kerbs in Alloa
Thinking about rooflight upstands & kerbs in Alloa? 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.
Stone villas, cottages and conservation areas across Scotland often call for conservation rooflights in slate roofs. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.

Consents for rooflight upstands & kerbs in Alloa
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. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.

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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
How do I book a survey in Alloa?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Alloa?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
