How we approach roof lanterns in Camborne
Thinking about roof lanterns in Camborne? 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Jobs in Camborne 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
- Aluminium or uPVC systems
- Internal and external colours
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Can include opening vents
- Adds visual height to a single-storey room
What to check first
- Needs a strong, level kerb or upstand
- Plaster-box depth affects how the lantern looks from below
Do you need permission in Camborne?
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. 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
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 Camborne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Camborne?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
