Dome rooflights for Southport: the essentials
We handle dome rooflights across Merseyside, including Southport. 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Southport, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We work across Merseyside, including Southport, and in neighbouring towns such as Formby and Lytham St Annes. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Southport
- Clear, opal or tinted
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Polycarbonate or acrylic
- Low cost per unit
- Smoke-vent versions available
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Southport
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.

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