Roof lanterns in Muswell Hill: what is involved?
Roof lanterns in Muswell Hill means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the N10 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Crouch End (2 km) and Wood Green (2 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Muswell Hill
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Roof lanterns in Muswell Hill: questions
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
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.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
