What do rooflight upstands & kerbs in Bath involve?
Thinking about rooflight upstands & kerbs in Bath? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.
Bath is the main town we list in Somerset; we also cover nearby Trowbridge and Kingswood.
What you can choose
- Proprietary insulated kerbs
- Internal plaster-box linings
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Raised upstands for deep green or ballasted roofs
- Membrane dressed up and sealed
- Insulated to avoid a cold bridge
Before you order: points to check
- Upstand size must match the unit within a tight tolerance
- Membrane compatibility with the rooflight's sealants
Do you need permission in Bath?
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.
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. 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.

Common questions
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
Can you work alongside my builder in Bath?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Bath free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
