What do rooflight upstands & kerbs in Harwich involve?
Thinking about rooflight upstands & kerbs in Harwich? 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
We work across Essex, including Harwich, and in neighbouring towns such as Felixstowe and Ipswich. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Proprietary insulated kerbs
- Internal plaster-box linings
- Timber upstands with insulation
- Insulated to avoid a cold bridge
- Built square to the rooflight size
Before you order: points to check
- Membrane compatibility with the rooflight's sealants
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Planning and building rules for Harwich
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.

Common questions
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.
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
