What do rooflight upstands & kerbs in Wembley involve?
Our rooflight upstands & kerbs service in Wembley covers insulated kerbs built and waterproofed to suit your rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
From Wembley to Harrow, Greenford and Willesden, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Wembley
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Rooflight upstands & kerbs in Wembley: questions
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
