How we approach dome rooflights in Holyhead
We handle dome rooflights across Gwynedd, including Holyhead. 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
From Holyhead to Llangefni, Caernarfon and Bangor, Gwynedd, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Holyhead project
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Low cost per unit
- Light, impact-resistant domes
Before you order: points to check
- Upstand condition decides whether you replace dome only or the whole unit
- Fire classification matters on some roofs
Building control and safety duties in Holyhead
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 non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Dome rooflights in Holyhead: questions
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.
Can domes open?
Hinged and vented domes are available, manual or electric.
