Dome rooflights in Farnham: what is involved?
Thinking about dome rooflights in Farnham? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Farnham is around 20 km from Woking, and we survey and fit throughout that part of Surrey, including the GU9 district.
Choices for your Farnham project
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Fixed, hinged or vented options
- Light, impact-resistant domes
Things we check at survey
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Farnham
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
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.

Dome rooflights in Farnham: questions
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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Do I need to be at home for the survey in Farnham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Farnham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
