What do roof lanterns in Carlisle involve?
For Carlisle 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Think of roof lanterns for rooms that need height as well as light.
We cover all of Carlisle and the CA1 district, and nearby Penrith and Keswick.
What you can choose
- Aluminium or uPVC systems
- Internal and external colours
- Solar-control or self-cleaning glass
- Rectangular, square or bespoke sizes
- Opening vents with electric control
- Double or triple glazed with solar-control options
- Classic look that suits period and modern homes
Before you order: points to check
- Larger lanterns may need a steel or timber ring beam
- Needs a strong, level kerb or upstand
Do you need permission in Carlisle?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. 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 Carlisle: 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.
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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Do I need to be at home for the survey in Carlisle?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
