Dome rooflights in Rhondda: what is involved?
Thinking about dome rooflights in Rhondda? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Dome rooflights suit schools, flats and commercial flat roofs.
We cover all of Rhondda and the CF42 district, and nearby Tonypandy and Aberdare.
Choices for your Rhondda project
- Twin, triple or quad skin
- Fall-through protection mesh
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Fixed, hinged or vented options
- 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
Building control and safety duties in Rhondda
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. Product data for building control is supplied with every quote.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fire classification of rooflight materials near boundaries is checked at specification.

Dome rooflights in Rhondda: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
How do I book a survey in Rhondda?
