What do rooflight upstands & kerbs in Littlehampton involve?
Our rooflight upstands & kerbs service in Littlehampton covers insulated kerbs built and waterproofed to suit your rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.
Littlehampton is around 42 km from Crawley, and we survey and fit throughout that part of West Sussex, including the BN17 district.

Do you need permission in Littlehampton?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Rooflight upstands & kerbs in Littlehampton: 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.
Will I need planning permission in Littlehampton?
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.
