Tubular Skylights (Sun Tunnels)

1. Pitched Roof / Sloped Roof Models These are low-profile dome-based collectors designed for pitched roofs (typically roofs with slopes 2:12 and steeper). The domes capture sunlight across a broad range of sun angles and use a single-piece flashing that integrates with asphalt shingles and similar roof coverings. Key features often include UV-blocking domes, condensation-release vents in the dome, and watertight flashings. Pitched roof models are ideal for hallways, bathrooms, kitchens, and rooms where the roof plane is sloped. Their low-profile design blends well with rooflines and is engineered to perform from sunup to sundown. citeturn0search0turn0search19

2. Flat Roof / Low-Slope Models Flat roof or low-slope installations use specially shaped domes or curb-mounted collectors that interface properly with membrane roofs, built-up roofs, and modified bitumen systems. Flat roof models typically include a flashing system that ensures a watertight seal and can be mounted directly to the roofing membrane or to a prefabricated curb. These models are commonly used for attic-less buildings, commercial flats, and garages where a pitched-roof collector is impractical. citeturn0search4turn0search3

3. Curb-Mount Models Curb-mount tubular skylights are designed to be installed on a pre-built curb. The curb mount option provides a robust and flexible installation for both residential and commercial roofs, and it is especially suitable when the roof has complex detailing or when a precise roof penetration is pre-planned during construction. Flood-resistant curb flashings and square-shaped cladding make curb-mount units adaptable to many roof finishes. citeturn0search3turn0search12

4. Tile Roof Models and Specialty Flashings For tile roofs, terracotta, or slate, the skylight system includes tile-specific skirts or flashing accessories to preserve watertight integrity and roofing aesthetics. These flashing accessories allow tubular skylights to be installed with minimal disruption to the original roof tiles and help maintain the roof’s finish while preventing leaks and ponding. Tile flashing kits and turret extensions are standard options for tile roof installations. citeturn0search25
