Dome rooflights for Prescot: the essentials
We handle dome rooflights across Merseyside, including Prescot. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
Neighbouring towns include Huyton (3 km) and St Helens (5 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fixed, hinged or vented options
- Suits schools, flats and commercial roofs
What to check first
- Old domes may be fragile — treat as fragile until checked
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Prescot
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. Product data for building control is supplied with every quote.
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 Prescot
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.
Can domes open?
Hinged and vented domes are available, manual or electric.
Do I need to be at home for the survey in Prescot?
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 Prescot?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
