Rooflight upstands & kerbs for Hythe: the essentials
For Hythe 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 East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Hythe, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
We work across Hampshire, including Hythe, and in neighbouring towns such as Southampton and Totton. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Proprietary insulated kerbs
- Timber upstands with insulation
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Internal plaster-box linings
- Upstand repairs and rebuilds
- Correct height above the finished roof
- Built square to the rooflight size
Things we check at survey
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Insulation continuity around the upstand affects condensation
Planning and building rules for Hythe
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. 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. 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.

Rooflight upstands & kerbs in Hythe: 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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Do I need to be at home for the survey in Hythe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
