How we approach roof lanterns in Borehamwood
Thinking about roof lanterns in Borehamwood? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Borehamwood, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Jobs in Borehamwood 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.
What you can choose
- Internal and external colours
- LED lighting in the plaster box
- Rectangular, square or bespoke sizes
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- Double or triple glazed with solar-control options
- Light from every angle across the day
Things we check at survey
- Some designs project above the roof enough to affect planning on certain houses
- Larger lanterns may need a steel or timber ring beam
Planning, building control and Borehamwood
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.

Questions about roof lanterns in Borehamwood
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.
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
