Roof lanterns in Harlow: what is involved?
Roof lanterns in Harlow means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the CM17 district and the rest of Essex, with a survey before any price is fixed.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
From Harlow to Hoddesdon, Bishop's Stortford and Waltham Abbey, the same survey-first process applies: measure, specify, fix the price, then fit.

- Opening vents with electric control
- LED lighting in the plaster box

Before you order: points to check

Planning, building control and Harlow
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. 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.
Read the planning permission guide before you commit to a design.

Roof lanterns in Harlow: 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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.
Is the survey in Harlow free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Harlow?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
