How we approach rooflight upstands & kerbs in Largs
We handle rooflight upstands & kerbs across Ayrshire, including Largs. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Neighbouring towns include Dunoon (17 km) and Greenock (18 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Largs?
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. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
Read the planning permission guide before you commit to a design.

Common questions
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Do I need to be at home for the survey in Largs?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Largs?
