Rooflight upstands & kerbs for Fleet: the essentials
Thinking about rooflight upstands & kerbs in Fleet? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Fleet is around 58 km from Southampton, and we survey and fit throughout that part of Hampshire, including the GU51 district.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Proprietary insulated kerbs
- Timber upstands with insulation
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Internal plaster-box linings
- Fixings and falls agreed with the rooflight maker
- Membrane dressed up and sealed
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 Fleet?
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.
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.

Questions about rooflight upstands & kerbs in Fleet
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Do I need to be at home for the survey in Fleet?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Fleet?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
