Dome rooflights in Maghull: what is involved?
Thinking about dome rooflights in Maghull? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Dome rooflights suit schools, flats and commercial flat roofs.
We work across Merseyside, including Maghull, and in neighbouring towns such as Kirkby and Litherland. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Maghull
- Clear, opal or tinted
- Fall-through protection mesh
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Quick replacement on existing upstands
- Smoke-vent versions available
Things we check at survey
- 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 Maghull
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. 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.
Read the planning permission guide before you commit to a design.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on 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 you work alongside my builder in Maghull?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Maghull?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
