Square roof lanterns for Clacton-on-Sea homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
In midsummer the noon sun stands about 61.7° high over Clacton-on-Sea, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Four triangular panes to a single apex
- Stock colours or any RAL on request
- No ridge, a neat apex cap instead

Planning and building regulations for Clacton-on-Sea
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 Clacton-on-Sea 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 Clacton-on-Sea
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
How quickly can I get a roof lantern in Clacton-on-Sea?
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 CO15.
Is it worth having solar-control glass in Clacton-on-Sea?
With the midsummer sun about 61.7° high at noon, roof glass in Clacton-on-Sea gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
