Dome rooflights in Frome: what is involved?
Dome rooflights in Frome means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the BA11 district and the rest of Somerset, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Frome, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We work across Somerset, including Frome, and in neighbouring towns such as Warminster and Trowbridge. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Twin, triple or quad skin
- Fall-through protection mesh
- Polycarbonate or acrylic
- Suits schools, flats and commercial roofs
- Low cost per unit
What to check first
- Old domes may be fragile — treat as fragile until checked
- Fire classification matters on some roofs
Regulations for dome rooflights in Frome
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. Fragile-roof safety and access are planned before work starts.

Questions about dome rooflights in Frome
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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.
Do I need to be at home for the survey in Frome?
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 Frome?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
