How we approach roof lanterns in Great Yarmouth
Our roof lanterns service in Great Yarmouth covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Great Yarmouth sits about 15 km from Lowestoft and 29 km from Norwich, and we cover the whole NR30 postcode district and the roads in between.

Do you need permission in Great Yarmouth?
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
