Planning and building regulations for Redruth
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
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 Redruth 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 Redruth
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.
Is it worth having solar-control glass in Redruth?
With the midsummer sun about 63.2° high at noon, roof glass in Redruth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Redruth?
