Dome rooflights for Lowestoft: the essentials
For Lowestoft homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Lowestoft, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Lowestoft is around 62 km from Ipswich, and we survey and fit throughout that part of Suffolk, including the NR32 district.
Specification options
- Fixed or hinged with vent
- Twin, triple or quad skin
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fall-through protection mesh
- Smoke-vent versions available
- Fixed, hinged or vented options
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
Rules and responsibilities in Lowestoft
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. 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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about dome rooflights in Lowestoft
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.
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.
Do I need to be at home for the survey in Lowestoft?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Lowestoft?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
