What do rooflight upstands & kerbs in Hoddesdon involve?
Rooflight upstands & kerbs in Hoddesdon means insulated kerbs built and waterproofed to suit your rooflight. We cover the EN11 district and the rest of Hertfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Hertford (6 km) and Cheshunt (7 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Hoddesdon?
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

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