Roof lanterns for Lowestoft: the essentials
Our roof lanterns service in Lowestoft 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Lowestoft, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Great Yarmouth (15 km) and Norwich (35 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Lowestoft
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Questions about roof lanterns in Lowestoft
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do I need to be at home for the survey in Lowestoft?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Lowestoft?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
