Dome rooflights in Highgate: what is involved?
We handle dome rooflights across Greater London, including Highgate. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Highgate, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
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
- Clear, opal or tinted
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Light, impact-resistant domes

Things we check at survey
- Fire classification matters on some roofs
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Highgate
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Highgate
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can domes open?
Hinged and vented domes are available, manual or electric.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
