Rectangular roof lanterns for Croydon homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
At 51.38°N, Croydon sees roughly 7h 51m of daylight in late December and 16h 37m in late June. A lantern faces the bright overhead sky all year, so it brings in useful light even on the short, grey days.
- Stock anthracite, black or white, or any RAL
- Intermediate rafters added on longer lengths
- Standard sizes or made to your kerb

Planning and building regulations for Croydon
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Croydon are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Croydon
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Can you fit a roof lantern in Croydon?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Croydon?
With the midsummer sun about 62.1° high at noon, roof glass in Croydon gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
