Rooflight upstands & kerbs in Grangemouth: what is involved?
We handle rooflight upstands & kerbs across the Forth Valley, including Grangemouth. 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.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Grangemouth sits about 4 km from Falkirk and 7 km from Bo'ness, and we cover the whole FK3 postcode district and the roads in between.

Do you need permission in Grangemouth?
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.

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.
Is the survey in Grangemouth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Grangemouth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
