Roof lanterns for Westhoughton: the essentials
For Westhoughton homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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.
We work across Greater Manchester, including Westhoughton, and in neighbouring towns such as Atherton and Hindley. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Westhoughton
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. 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.
Our planning guide covers each nation in more detail.

Questions about roof lanterns in Westhoughton
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.
Will I need planning permission in Westhoughton?
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.
