Dome rooflights for Kirkby: the essentials
Thinking about dome rooflights in Kirkby? 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. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
We work across Merseyside, including Kirkby, and in neighbouring towns such as Maghull and Litherland. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Kirkby project
- Fall-through protection mesh
- Clear, opal or tinted
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Suits schools, flats and commercial roofs
- Quick replacement on existing upstands
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
Rules and responsibilities in Kirkby
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Kirkby
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.
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 Kirkby?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
