What do rooflight upstands & kerbs in Burnham-on-Sea involve?
For Burnham-on-Sea 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.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. In Burnham-on-Sea, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
Burnham-on-Sea is around 47 km from Bath, and we survey and fit throughout that part of Somerset, including the TA8 district.

- Internal plaster-box linings
- Raised upstands for deep green or ballasted roofs

- Timber upstands with insulation

- Insulated to avoid a cold bridge
What to check first
- Upstand size must match the unit within a tight tolerance
- Membrane compatibility with the rooflight's sealants
Do you need permission in Burnham-on-Sea?
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Common 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.
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.
Can you work alongside my builder in Burnham-on-Sea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Burnham-on-Sea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
