Rectangular roof lanterns for Garston homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 60.1° high over Garston, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Suits kitchen-diners and rear extensions

Planning and building regulations for Garston
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.
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 Garston 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 Garston
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.
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.
How quickly can I get a roof lantern in Garston?
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 L19.
Is it worth having solar-control glass in Garston?
With the midsummer sun about 60.1° high at noon, roof glass in Garston gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
