Roof lanterns for Southall: the essentials
Thinking about roof lanterns in Southall? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Southall, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Jobs in Southall 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
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Internal and external colours
- Aluminium or uPVC systems
- Opening vents with electric control
- Can include opening vents
- Classic look that suits period and modern homes
Things we check at survey
- 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 Southall
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.
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.

Common 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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.

Yes for new installations. Repair visits are charged, and we tell you the price before we book.
