Rooflight upstands & kerbs for Bromley: the essentials
Thinking about rooflight upstands & kerbs in Bromley? 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.
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. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.
Bromley sits about 3 km from Beckenham and 5 km from Catford, and we cover the whole BR1 postcode district and the roads in between.

Planning and building rules for Bromley
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.
Read the planning permission guide before you commit to a design.

Common questions
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Do you offer rooflight upstands & kerbs in Bromley?
Yes. We carry out rooflight upstands & kerbs in Bromley and across Greater London. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Bromley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
