Roof lanterns in Bromley: what is involved?
Roof lanterns in Bromley means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the BR1 district and the rest of Greater London, with a survey before any price is fixed.
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. In Bromley, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
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
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. 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.

Roof lanterns in Bromley: questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Do I need to be at home for the survey in Bromley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Do you fit roof lanterns in Bromley?
Yes. We survey and fit roof lanterns in Bromley and across Greater London. Send your postcode and we will offer a survey date when we reply.
