What do dome rooflights in Chiswick involve?
For Chiswick 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Dome rooflights suit older flat roofs with yellowed or leaking domes.
From Chiswick to Hammersmith, Acton and Barnes, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Fall-through protection mesh
- Fixed or hinged with vent
- Twin, triple or quad skin
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Low cost per unit
- Suits schools, flats and commercial roofs
Before you order: points to check
- Old domes may be fragile — treat as fragile until checked
- Fire classification matters on some roofs
Rules and responsibilities in Chiswick
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 Chiswick
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on 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.
