Rooflight upstands & kerbs in Bridport: what is involved?
For Bridport 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Jobs in Bridport are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Proprietary insulated kerbs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Correct height above the finished roof
- Insulated to avoid a cold bridge
Before you order: points to check
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Membrane compatibility with the rooflight's sealants
Consents for rooflight upstands & kerbs in Bridport
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. 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.

Rooflight upstands & kerbs in Bridport: questions
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
