What do dome rooflights in Tonypandy involve?
Thinking about dome rooflights in Tonypandy? 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. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Tonypandy sits about 4 km from Rhondda and 8 km from Pontypridd, and we cover the whole CF40 postcode district and the roads in between.
Choices for your Tonypandy project
- Polycarbonate or acrylic
- Clear, opal or tinted
- Twin, triple or quad skin
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Smoke-vent versions available
- Suits schools, flats and commercial roofs
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Tonypandy
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 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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
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 Tonypandy?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.

Yes. We survey and fit dome rooflights in Tonypandy and across Mid Glamorgan. Send your postcode and we will offer a survey date when we reply.
