Rectangular roof lanterns for Preston homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
On the shortest day Preston gets about 7h 25m of daylight, with the sun only 12.8° above the horizon at noon. Light from the sky overhead is the brightest available in winter, which is exactly what a roof lantern collects.
- Suits kitchen-diners and rear extensions
- Ridge along the long axis, four glazed slopes
- Intermediate rafters added on longer lengths

Planning and building regulations for Preston
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Preston 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 Preston
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 a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
How quickly can I get a roof lantern in Preston?
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 PR1.
Who checks building regulations for a lantern in Preston?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
