How we approach rooflight upstands & kerbs in Crowthorne
We handle rooflight upstands & kerbs across Berkshire, including Crowthorne. 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Crowthorne, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Sandhurst (3 km) and Yateley (4 km). We offer a survey date when we reply to your enquiry.

Consents for rooflight upstands & kerbs in Crowthorne
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 Crowthorne
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
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.
