How we approach roof lanterns in Towcester
Roof lanterns in Towcester means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the NN12 district and the rest of Northamptonshire, with a survey before any price is fixed.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. In Towcester, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
We work across Northamptonshire, including Towcester, and in neighbouring towns such as Northampton and Daventry. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Towcester
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.
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.

Questions about roof lanterns in Towcester
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.
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.
