How Clogged Gutters Lead To Roof Leaks

Gutters Are Designed To Channel Water Away From The Roof And Foundation; when they clog, the system fails and water follows the path of least resistance, which often means into roof assemblies. Overflowing gutters spill water over the roof edge, saturating fascia boards and underlayment. Persistent moisture accelerates rot and can create pathways for water to penetrate into attics and living spaces.

Standing Water In Gutters Also Increases Weight And Stress On The Roof Edge,
