The answer to 'why is my skylight water stains' is that there are several common causes, including improper installation, cracked or damaged seals, and condensation buildup. Symptoms may include visible water stains, leaks, or moisture around the skylight. Solutions can range from minor DIY repairs to professional skylight replacement, depending on the severity of the issue.
Skylights are vulnerable to water damage over time due to the exposed nature of their installation. Improper sealing during installation can allow water to seep in, while cracks or deterioration in the seals around the skylight can also lead to leaks. Condensation buildup, often caused by poor ventilation, can also cause water stains and damage.
