What do dome rooflights in Runcorn involve?
Thinking about dome rooflights in Runcorn? 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.
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. Dome rooflights suit older flat roofs with yellowed or leaking domes.
We work across Cheshire, including Runcorn, and in neighbouring towns such as Widnes and Halewood. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Polycarbonate or acrylic
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Fixed or hinged with vent
- Smoke-vent versions available
- Suits schools, flats and commercial roofs
Things we check at survey
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Regulations for dome rooflights in Runcorn
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.
Read the planning permission guide before you commit to a design.

Dome rooflights in Runcorn: questions
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
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.
Do I need to be at home for the survey in Runcorn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
