What do dome rooflights in King's Lynn involve?
Thinking about dome rooflights in King's Lynn? 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. In King's Lynn, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We work across Norfolk, including King's Lynn, and in neighbouring towns such as Wisbech and March. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Clear, opal or tinted
- Smoke-vent versions available
- Light, impact-resistant domes
What to check first
- Old domes may be fragile — treat as fragile until checked
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in King's Lynn
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Common questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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 you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
