Flat rooflights for Derby homes
A single near-flat pane on an upstand: minimal, low and discreet.
At 52.92°N, Derby sees roughly 7h 34m of daylight in late December and 16h 55m in late June. A lantern faces the bright overhead sky all year, so it brings in useful light even on the short, grey days.
- Sized to your upstand
- Very low profile from outside

Planning and building regulations for Derby
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Derby 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 Derby
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
How quickly can I get a roof lantern in Derby?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for DE1.
Is it worth having solar-control glass in Derby?
With the midsummer sun about 60.5° high at noon, roof glass in Derby gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
