What do dome rooflights in Liverpool involve?
Dome rooflights in Liverpool means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the L1 district and the rest of Merseyside, with a survey before any price is fixed.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Dome rooflights suit schools, flats and commercial flat roofs.
Liverpool is the main town we list in Merseyside; we also cover nearby Birkenhead and Wallasey.
Choices for your Liverpool project
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Light, impact-resistant domes

Before you order: points to check
- Old domes may be fragile — treat as fragile until checked
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Liverpool
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Liverpool: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
