What do roof lanterns in Sudbury involve?
We handle roof lanterns across Suffolk, including Sudbury. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. In Sudbury, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Jobs in Sudbury are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Sudbury
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Solar-control or self-cleaning glass

Before you order: points to check
- Plaster-box depth affects how the lantern looks from below
- Larger lanterns may need a steel or timber ring beam
Do you need permission in Sudbury?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.

Yes. We survey and fit roof lanterns in Sudbury and across Suffolk. Send your postcode and we will offer a survey date when we reply.
