DOME SKYLIGHT
SYSTEM
Dome skylights are raised rooflight systems designed to bring natural light into the space below while supporting practical roof performance. Their domed shape helps manage water runoff effectively, which makes them especially useful where drainage, weather exposure, and durability all need to be considered carefully.
​
Unlike flatter skylight types that are often selected for a more minimal architectural look, dome skylights are generally chosen for their practical strength and dependable performance. They suit projects where the skylight needs to work reliably over time without becoming the main design feature of the roof.
Built to Perform in the Most Demanding Roofing Conditions
Flat skylights are glazed rooflight systems designed to bring natural light into the space below through a streamlined roof opening. They are often selected for projects that need overhead daylight with a more subtle architectural expression.
Rather than becoming the main feature of the roof, flat skylights support the overall design of the building. This makes them especially well suited to modern homes, commercial interiors, and architectural spaces where simplicity and finish matter.
Compared with more raised or feature-led skylight types, flat skylights are typically chosen for their balanced appearance, design flexibility, and ability to deliver daylight in a clean, contemporary way.

Get the Right Dome Skylight for Your Roof
