What are dome rooflights?
Dome rooflights in Dyfed means polycarbonate and acrylic domes for flat roofs, new or replacement. Every quote follows a survey of the roof and the room below.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best.

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. We confirm the route for your building before ordering.
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.

Common questions
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 replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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 you fit dome rooflights across Dyfed?
Yes. We survey and fit dome rooflights across Dyfed, including Llanelli, Ammanford, Aberystwyth.
