Dome rooflights in Formby: what is involved?
We handle dome rooflights across Merseyside, including Formby. 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.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. In Formby, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Jobs in Formby are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Clear, opal or tinted
- Fixed or hinged with vent
- Fall-through protection mesh
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Low cost per unit
- Smoke-vent versions available
Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Formby
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Dome rooflights in Formby: questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can domes open?
Hinged and vented domes are available, manual or electric.
Do you fit dome rooflights in Formby?
Yes. We survey and fit dome rooflights in Formby and across Merseyside. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Formby?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
