What do roof lanterns in King's Lynn involve?
Thinking about roof lanterns in King's Lynn? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
We work across Norfolk, including King's Lynn, and in neighbouring towns such as Wisbech and March. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for King's Lynn
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
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.

Roof lanterns in King's Lynn: 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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do I need to be at home for the survey in King's Lynn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in King's Lynn?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
