Roof lanterns in Felixstowe: what is involved?
Our roof lanterns service in Felixstowe covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 Felixstowe, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
Felixstowe sits about 5 km from Harwich and 17 km from Ipswich, and we cover the whole IP11 postcode district and the roads in between.

Things we check at survey
- Plaster-box depth affects how the lantern looks from below
- Some designs project above the roof enough to affect planning on certain houses
Planning and building rules for Felixstowe
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Questions about roof lanterns in Felixstowe
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do you fit roof lanterns in Felixstowe?
Yes. We survey and fit roof lanterns in Felixstowe and across Suffolk. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Felixstowe?
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.
