Dome rooflights in Ruislip: what is involved?
We handle dome rooflights across Greater London, including Ruislip. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Ruislip sits about 5 km from Northolt and 5 km from Uxbridge, and we cover the whole HA4 postcode district and the roads in between.
Choices for your Ruislip project
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fall-through protection mesh
- Polycarbonate or acrylic
- Low cost per unit
- Quick replacement on existing upstands
Before you order: points to check
- Old domes may be fragile — treat as fragile until checked
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Ruislip
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.

Questions about dome rooflights in Ruislip
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 you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
How do I book a survey in Ruislip?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Ruislip?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
