Dome rooflights in Cricklewood: what is involved?
Our dome rooflights service in Cricklewood 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Dome rooflights suit schools, flats and commercial flat roofs.
Neighbouring towns include Kilburn (2 km) and Hampstead (2 km). We offer a survey date when we reply to your enquiry.
Choices for your Cricklewood project
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Clear, opal or tinted
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Light, impact-resistant domes
- Fixed, hinged or vented options
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Rules and responsibilities in Cricklewood
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.

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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you work alongside my builder in Cricklewood?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Cricklewood?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
