Roof lanterns for Rochester: the essentials
We handle roof lanterns across Kent, including Rochester. 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. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
Rochester is around 13 km from Maidstone, and we survey and fit throughout that part of Kent, including the ME1 district.

Things we check at survey

- Larger lanterns may need a steel or timber ring beam
Planning, building control and Rochester
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Common 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.
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.
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.
