How we approach roof lanterns in Colne
We handle roof lanterns across Lancashire, including Colne. 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. Typical uses for roof lanterns include rooms that need height as well as light.
Jobs in Colne 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.
Specification options
- Aluminium or uPVC systems
- Internal and external colours
- LED lighting in the plaster box

Things we check at survey
- Needs a strong, level kerb or upstand
- Some designs project above the roof enough to affect planning on certain houses
Planning, building control and Colne
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Roof lanterns in Colne: questions
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.
How do I book a survey in Colne?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Colne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
