Rooflight upstands & kerbs for Kenilworth: the essentials
Thinking about rooflight upstands & kerbs in Kenilworth? 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.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Kenilworth is around 21 km from Nuneaton, and we survey and fit throughout that part of Warwickshire, including the CV8 district.

Planning, building control and Kenilworth
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.

Rooflight upstands & kerbs in Kenilworth: questions
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Do I need to be at home for the survey in Kenilworth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Kenilworth?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
