Rooflight upstands & kerbs in St Ives: what is involved?
We handle rooflight upstands & kerbs across Cambridgeshire, including St Ives. 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
Jobs in St Ives are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

What to check first

Planning and building rules for St Ives
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about rooflight upstands & kerbs in St Ives
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
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 St Ives?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in St Ives free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
