Dome rooflights in Sandy: what is involved?
Thinking about dome rooflights in Sandy? 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 South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Sandy, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Jobs in Sandy are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Polycarbonate or acrylic
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Twin, triple or quad skin
- Smoke-vent versions available
- Quick replacement on existing upstands
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Sandy
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.
Our planning guide covers each nation in more detail.
