What do roof lanterns in Fishponds involve?
We handle roof lanterns across Bristol, including Fishponds. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
Fishponds is around 6 km from Bristol, and we survey and fit throughout that part of Bristol, including the BS16 district.

Before you order: points to check
- Plaster-box depth affects how the lantern looks from below
- Some designs project above the roof enough to affect planning on certain houses
Consents for roof lanterns in Fishponds
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about roof lanterns in Fishponds
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.
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.
Is the survey in Fishponds free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Fishponds?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
