Walk-on rooflights for Borehamwood: the essentials
Thinking about walk-on rooflights in Borehamwood? The short answer: structural glass you can stand on, set flush into terraces and floors. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Walk-on rooflights suit roof terraces, balconies and floors above basements.
We work across Hertfordshire, including Borehamwood, and in neighbouring towns such as Barnet and Bushey. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Borehamwood project

Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Planning, building control and Borehamwood
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. 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.
Read the planning permission guide before you commit to a design.

Common questions
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Do I need to be at home for the survey in Borehamwood?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Borehamwood?
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.
