Conservation rooflights in Highgate: what is involved?
Thinking about conservation rooflights in Highgate? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Highgate, as anywhere, conservation rooflights are the usual choice for slate and plain-tile roofs where a quiet roofline matters.
Jobs in Highgate 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.
Options we can specify in Highgate
- Steel or aluminium frames
- Flashings for slate or plain tile
- Toughened or laminated double glazing
- Blinds
- Central vertical glazing bar
- Often preferred by conservation officers
- Optional central glazing bar
What to check first

Planning, building control and Highgate
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. 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.
