What do conservation rooflights in Barnet involve?
Our conservation rooflights service in Barnet covers slim, low-profile steel-look rooflights for period and listed roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Conservation rooflights suit slate and plain-tile roofs where a quiet roofline matters.
We work across Greater London, including Barnet, and in neighbouring towns such as Potters Bar and Borehamwood. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Steel or aluminium frames
- Toughened or laminated double glazing
- Blinds
- Flashings for slate or plain tile
- Central vertical glazing bar
- Steel or aluminium frame in black or grey
- Traditional slim profile, sits low in the roof
Things we check at survey
- Projection above the roof line is limited — usually as flush as possible
- Conservation officers may specify size and position
Consents for conservation rooflights in Barnet
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
