When a Solatube tubular skylight is installed correctly with the proper flashing and roof seal, it shouldn’t leak. Solatube Daylighting Systems are engineered with roof specific flashing, integrated curb systems, and weather sealing designed to handle normal rain, wind, and roof movement.
Leaks typically occur only when a roof penetration is installed incorrectly, or when older systems have flashing that no longer matches the roof condition; that’s why professional installation matters. A trained installer ensures the flashing matches the roof type, the roof pitch is correct for the model, and all seals are properly integrated with the roofing material.
Like any roof penetration, tubular skylights should be inspected if the roof is replaced or repaired. When installed and maintained properly, a Solatube tubular skylight system does not create an ongoing leak risk.
