How we approach rooflight upstands & kerbs in Renfrew
For Renfrew homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Tenements and flats are common in Scottish towns and cities, where rooflights over stairwells and top-floor flats need the owners' and factor's agreement. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
Neighbouring towns include Clydebank (3 km) and Erskine (5 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Renfrew
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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 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.

Yes for new installations. Repair visits are charged, and we tell you the price before we book.
