Rectangular roof lanterns for Colchester homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 61.6° high over Colchester, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- The most size options of any lantern shape
- Intermediate rafters added on longer lengths
- Ridge along the long axis, four glazed slopes

Planning and building regulations for Colchester
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 Colchester 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 Colchester
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.
Can you fit a roof lantern in Colchester?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Do you deliver roof lanterns to Colchester?
Yes. Delivery to Colchester (CO1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
