Dome rooflights for Sudbury: the essentials
Thinking about dome rooflights in Sudbury? 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Sudbury, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Sudbury is around 29 km from Ipswich, and we survey and fit throughout that part of Suffolk, including the CO10 district.
What you can choose
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Clear, opal or tinted
- Fall-through protection mesh
- Fixed or hinged with vent
- Low cost per unit
- Fixed, hinged or vented options
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Building control and safety duties in Sudbury
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Sudbury: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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 work alongside my builder in Sudbury?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Sudbury?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
