Roof lanterns for Altrincham: the essentials
We handle roof lanterns across Greater Manchester, including Altrincham. 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
We work across Greater Manchester, including Altrincham, and in neighbouring towns such as Sale and Urmston. Access, parking and how the glass reaches the roof are all checked at the survey.

- Internal and external colours
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Opening vents with electric control
- Adds visual height to a single-storey room
- Light from every angle across the day
Things we check at survey
- Larger lanterns may need a steel or timber ring beam
- Needs a strong, level kerb or upstand
Planning, building control and Altrincham
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about roof lanterns in Altrincham
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
How do I book a survey in Altrincham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Altrincham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
