What do rooflight upstands & kerbs in Worthing involve?
For Worthing homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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.
From Worthing to Portslade, Littlehampton and Hove, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Internal plaster-box linings
- Proprietary insulated kerbs
- Timber upstands with insulation
- Membrane dressed up and sealed
- Insulated to avoid a cold bridge
What to check first
- Membrane compatibility with the rooflight's sealants
- Upstand size must match the unit within a tight tolerance
Do you need permission in Worthing?
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. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Worthing
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 Worthing free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Worthing?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
