Roof lanterns in Farnworth: what is involved?
We handle roof lanterns across Greater Manchester, including Farnworth. 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. Think of roof lanterns for rooms that need height as well as light.
Jobs in Farnworth 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.
Options we can specify in Farnworth
- LED lighting in the plaster box
- Internal and external colours
- Opening vents with electric control
- Solar-control or self-cleaning glass
- Aluminium or uPVC systems
- Adds visual height to a single-storey room
- Classic look that suits period and modern homes
Before you order: points to check
- Larger lanterns may need a steel or timber ring beam
- Some designs project above the roof enough to affect planning on certain houses
Consents for roof lanterns in Farnworth
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Roof lanterns in Farnworth: questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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 I need to be at home for the survey in Farnworth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
