Dome rooflights for St Ives: the essentials
Dome rooflights in St Ives means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the PE27 district and the rest of Cambridgeshire, with a survey before any price is fixed.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Dome rooflights suit schools, flats and commercial flat roofs.
We work across Cambridgeshire, including St Ives, and in neighbouring towns such as Huntingdon and St Neots. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Polycarbonate or acrylic
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Clear, opal or tinted
- Light, impact-resistant domes
- Smoke-vent versions available
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in St Ives
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
How do I book a survey in St Ives?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in St Ives?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
