Dome rooflights for Derby: the essentials
For Derby homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Derby is the main town we list in Derbyshire; we also cover nearby Belper and Ilkeston.
Specification options
- Fall-through protection mesh
- Polycarbonate or acrylic
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Low cost per unit
- Fixed, hinged or vented options
What to check first
- Old domes may be fragile — treat as fragile until checked
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Derby
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.

Common questions
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can domes open?
Hinged and vented domes are available, manual or electric.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
