Roof lanterns in Dronfield: what is involved?
Our roof lanterns service in Dronfield 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.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
Jobs in Dronfield are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning and building rules for Dronfield
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.
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. 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.

Questions about roof lanterns in Dronfield
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.
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 you fit roof lanterns in Dronfield?
Yes. We survey and fit roof lanterns in Dronfield and across Derbyshire. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Dronfield?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
