What are rooflight upstands & kerbs?
Rooflight upstands & kerbs in Glasgow and Dunbartonshire means insulated kerbs built and waterproofed to suit your rooflight. Every quote follows a survey of the roof and the room below.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters.

Planning and building rules in Scotland
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Listed buildings need listed building consent where the work affects their character.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.

Common questions
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.
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Do I need to be at home for the survey in Glasgow and Dunbartonshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
