When water backs up in a skylight, the primary issue is often related to drainage problems. Clearing the drainage is essential because pooled water can lead to leaks and further damage to the skylight and surrounding structures.

By ensuring that the drainage is unobstructed, you allow water to flow freely away from the skylight, reducing the risk of backup. This often involves removing leaves, debris, or any materials that have accumulated and may obstruct the water's exit path.

Addressing drainage first is crucial before considering more drastic measures such as replacing the skylight, sealing edges, or installing new flashing, which may not resolve the underlying problem of water pooling. Proper drainage maintenance can prevent many issues related to skylights and extend their lifespan significantly.
