How we approach rooflight upstands & kerbs in Hove
Rooflight upstands & kerbs in Hove means insulated kerbs built and waterproofed to suit your rooflight. We cover the BN3 district and the rest of East Sussex, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
We work across East Sussex, including Hove, and in neighbouring towns such as Brighton and Portslade. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Hove
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Rooflight upstands & kerbs in Hove: 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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
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.
Will I need planning permission in Hove?
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.
Do I need to be at home for the survey in Hove?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
