What do roof lanterns in Atherton involve?
Roof lanterns in Atherton means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the M46 district and the rest of Greater Manchester, with a survey before any price is fixed.
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. Typical uses for roof lanterns include rooms that need height as well as light.
From Atherton to Tyldesley, Westhoughton and Leigh, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Aluminium or uPVC systems
- Opening vents with electric control
- Solar-control or self-cleaning glass
- Internal and external colours
- LED lighting in the plaster box
- Slim aluminium bars, more glass
- Can include opening vents
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
Do you need permission in Atherton?
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

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