Downspout Help
Downspouts are an easy-to-overlook part of gutter performance. HSRC helps homeowners understand common downspout questions.
Downspouts move rainwater from the gutters to the ground. Their number, placement, and discharge direction affect how well water is directed away from the foundation, landscaping, and walkways.
Key Takeaways
- Downspouts should discharge water away from the home.
- Too few downspouts can cause overflow even with clean gutters.
- Extensions, splash blocks, and buried drains are common options.
- Discharge near the foundation may contribute to moisture issues.
- Clogged downspouts are a common cause of overflow.
Overview: Downspout Help
Most homes benefit from downspouts placed at strategic corners so water flows away from doors, patios, and foundations.
In areas with heavy rainfall, additional downspouts may reduce overflow risk.
What Homeowners Should Consider
Buried drain systems can move water further away but need maintenance to avoid clogs.
Splash blocks are a low-cost way to direct water, but may not be enough for larger roofs.
