How we approach rooflight upstands & kerbs in Bognor Regis
Rooflight upstands & kerbs in Bognor Regis means insulated kerbs built and waterproofed to suit your rooflight. We cover the PO21 district and the rest of West Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.
From Bognor Regis to Chichester, Littlehampton and Worthing, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Bognor Regis
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Rooflight upstands & kerbs in Bognor Regis: questions
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.
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.
Is the survey in Bognor Regis free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Bognor Regis?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
