Skylight Leaking? Common Causes and Roof Skylight Repair Solutions

residential roofing services

Skylight leaks typically stem from failed flashing systems, seal deterioration, or condensation issues rather than obvious structural damage. This guide identifies the root causes of skylight water infiltration and provides a clear framework for deciding between repair and replacement. Key factors include the age of the installation, extent of water damage, and underlying cause of the leak. Simple seal repairs cost $200-400, while complete flashing replacement ranges $400-800, and full skylight replacement runs $800-2000. Most skylights over 12 years old with multiple issues benefit more from replacement than repeated repairs. Professional assessment through water testing identifies exact problem sources, preventing costly guesswork. Preventive maintenance includes seasonal debris clearing and seal inspection to catch minor issues before they become major problems.
