Roof lanterns in Ipswich: what is involved?
Thinking about roof lanterns in Ipswich? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
We cover all of Ipswich and the IP1 district, and nearby Harwich and Felixstowe.

Do you need permission in Ipswich?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Can you work alongside my builder in Ipswich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Ipswich?
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.
