How we approach roof lanterns in Dukinfield
We handle roof lanterns across Greater Manchester, including Dukinfield. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. In Dukinfield, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
From Dukinfield to Ashton-under-Lyne, Stalybridge and Hyde, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Opening vents with electric control
- Rectangular, square or bespoke sizes
- Internal and external colours
- Adds visual height to a single-storey room
- Double or triple glazed with solar-control options
What to check first
- Some designs project above the roof enough to affect planning on certain houses
- Plaster-box depth affects how the lantern looks from below
Planning and building rules for Dukinfield
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 Dukinfield: questions
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
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.
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.
Can you work alongside my builder in Dukinfield?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Dukinfield?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
