Gutters are an essential part of the building envelope because they divert roof water away from the foundation.
If gutter systems are not maintained well or are damaged, roof water can seep into the foundation backfill and affect the foundation's soil and structural stability. Some soil types are sensitive to water.
Chapter 29 (Section P2912.5) of the International Residential Code (IRC) applies to roof drainage and gutters.
Common Gutter Conditions
Gutters, downspouts, extensions, and discharge points need continuous maintenance and must be repaired if damaged.
1. Disconnected Gutter Components
2. Damaged Gutter Downspouts
3. Upright Gutter Extensions
4. Barriers to Flow: Sidewalks
5. Barriers to Flow: Non-Perforated Lawn Edging
6. Barriers to Flow: Curbs

8. Discharge to Low Spots Around the Foundation
