Dome rooflights in Dagenham: what is involved?
Dome rooflights in Dagenham means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the RM10 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Dagenham, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Jobs in Dagenham 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.
Options we can specify in Dagenham
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Smoke-vent versions available
- Suits schools, flats and commercial roofs
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Rules and responsibilities in Dagenham
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
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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.
Do I need to be at home for the survey in Dagenham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
