What do roof lanterns in Alnwick involve?
For Alnwick homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. Typical uses for roof lanterns include rooms that need height as well as light.
Alnwick is around 34 km from Blyth, and we survey and fit throughout that part of Northumberland, including the NE66 district.

Do you need permission in Alnwick?
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. 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 Alnwick: 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.
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 you fit roof lanterns in Alnwick?
Yes. We survey and fit roof lanterns in Alnwick and across Northumberland. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Alnwick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
