Rooflight upstands & kerbs for Haywards Heath: the essentials
Rooflight upstands & kerbs in Haywards Heath means insulated kerbs built and waterproofed to suit your rooflight. We cover the RH16 district and the rest of West Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Haywards Heath, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Burgess Hill (5 km) and Crawley (14 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Haywards Heath
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.
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. 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 Haywards Heath
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
Can you work alongside my builder in Haywards Heath?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Haywards Heath free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
