How we approach rooflight upstands & kerbs in Christchurch
For Christchurch 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Jobs in Christchurch 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
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Upstand repairs and rebuilds
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Fixings and falls agreed with the rooflight maker
- Matched to your roof covering
Things we check at survey
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Upstand size must match the unit within a tight tolerance
Do you need permission in Christchurch?
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Questions about rooflight upstands & kerbs in Christchurch
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Will I need planning permission in Christchurch?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
Is the survey in Christchurch free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
