How we approach roof lanterns in Ormskirk
For Ormskirk 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Ormskirk, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Ormskirk is around 25 km from Preston, and we survey and fit throughout that part of Lancashire, including the L39 district.
Specification options
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Internal and external colours
- Opening vents with electric control
- Aluminium or uPVC systems
- Adds visual height to a single-storey room
- Can include opening vents
Before you order: points to check
- Larger lanterns may need a steel or timber ring beam
- Needs a strong, level kerb or upstand
Planning and building rules for Ormskirk
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.
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.
Read the planning permission guide before you commit to a design.

Roof lanterns in Ormskirk: questions
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.
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Is the survey in Ormskirk free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Ormskirk?
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.
