How we approach rooflight upstands & kerbs in Maghull
Rooflight upstands & kerbs in Maghull means insulated kerbs built and waterproofed to suit your rooflight. We cover the L31 district and the rest of Merseyside, with a survey before any price is fixed.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. In Maghull, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
From Maghull to Kirkby, Litherland and Ormskirk, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Maghull
- Upstand repairs and rebuilds
- Internal plaster-box linings

Planning and building rules for Maghull
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Maghull
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.
Can you work alongside my builder in Maghull?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Maghull free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
