Rooflight upstands & kerbs for Skelmersdale: the essentials
Thinking about rooflight upstands & kerbs in Skelmersdale? 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Skelmersdale is around 24 km from Preston, and we survey and fit throughout that part of Lancashire, including the WN8 district.
What you can choose
- Internal plaster-box linings
- Proprietary insulated kerbs
- Timber upstands with insulation
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Raised upstands for deep green or ballasted roofs
- Built square to the rooflight size
- Insulated to avoid a cold bridge
What to check first
- Insulation continuity around the upstand affects condensation
- Upstand size must match the unit within a tight tolerance
Planning, building control and Skelmersdale
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. 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.

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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Do I need to be at home for the survey in Skelmersdale?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Skelmersdale free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
