Roof lanterns in Cromer: what is involved?
Roof lanterns in Cromer means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the NR27 district and the rest of Norfolk, with a survey before any price is fixed.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
From Cromer to Fakenham, Norwich and Wymondham, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for roof lanterns in Cromer
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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 Cromer: questions
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 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.
Will I need planning permission in Cromer?
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.
How do I book a survey in Cromer?
