What do dome rooflights in Hampstead involve?
Our dome rooflights service in Hampstead covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Dome rooflights suit schools, flats and commercial flat roofs.
Jobs in Hampstead 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
- Fixed or hinged with vent
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Low cost per unit
- Suits schools, flats and commercial roofs
Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Fire classification matters on some roofs
Regulations for dome rooflights in Hampstead
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
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.

Dome rooflights in Hampstead: questions
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 domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can you work alongside my builder in Hampstead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Hampstead?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
