The Solatube Daylighting System circular one piece seamless flashing design allows rain and debris to naturally bypass the unit. The Solatube flashings have no joints or weak points that may separate and allow water to enter.

Traditional skylights have a reputation of leaking. Many times this is an issue of incorrect installation, but their square design invites problems. First, the flat up-slope side collects branches, leaves and other debris, which interferes with proper drainage. As the water dams up, it migrates under shingles or tiles to find an escape route, causing leaking.
