How we approach roof lanterns in Tewkesbury
We handle roof lanterns across Gloucestershire, including Tewkesbury. 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Tewkesbury, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Tewkesbury is around 15 km from Gloucester, and we survey and fit throughout that part of Gloucestershire, including the GL20 district.

Planning and building rules for Tewkesbury
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. 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.

Common questions
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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 you fit roof lanterns in Tewkesbury?
Yes. We survey and fit roof lanterns in Tewkesbury and across Gloucestershire. Send your postcode and we will offer a survey date when we reply.
Is the survey in Tewkesbury free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
