How we approach rooflight upstands & kerbs in King's Lynn
We handle rooflight upstands & kerbs across Norfolk, including King's Lynn. 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.
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. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
We work across Norfolk, including King's Lynn, and in neighbouring towns such as Wisbech and March. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for King's Lynn
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. 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.

Questions about rooflight upstands & kerbs in King's Lynn
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Is the survey in King's Lynn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in King's Lynn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
