Dome rooflights in Lancaster: what is involved?
For Lancaster 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Neighbouring towns include Morecambe (5 km) and Fleetwood (19 km). We offer a survey date when we reply to your enquiry.
Specification options
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Suits schools, flats and commercial roofs
- Fixed, hinged or vented options
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Rules and responsibilities in Lancaster
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.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Lancaster
Can domes open?
Hinged and vented domes are available, manual or electric.
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.
Do you fit dome rooflights in Lancaster?
Yes. We survey and fit dome rooflights in Lancaster and across Lancashire. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Lancaster?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
