Roof lanterns for Farnham: the essentials
We handle roof lanterns across Surrey, including Farnham. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Roof lanterns suit rooms that need height as well as light.
Farnham sits about 5 km from Aldershot and 8 km from Fleet, and we cover the whole GU9 postcode district and the roads in between.

Things we check at survey

Planning and building rules for Farnham
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.

Roof lanterns in Farnham: 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.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Can you work alongside my builder in Farnham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
