How we approach rooflight upstands & kerbs in Kirkby
We handle rooflight upstands & kerbs across Merseyside, including Kirkby. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Kirkby, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
From Kirkby to Maghull, Litherland and Prescot, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation
- Proprietary insulated kerbs
- Internal plaster-box linings
- Membrane dressed up and sealed
- Correct height above the finished roof
Before you order: points to check
- Upstand size must match the unit within a tight tolerance
- Insulation continuity around the upstand affects condensation
Do you need permission in Kirkby?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
Read the planning permission guide before you commit to a design.

Questions about rooflight upstands & kerbs in Kirkby
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Will I need planning permission in Kirkby?
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.
Do I need to be at home for the survey in Kirkby?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
