DOWNSPOUTS

What Are Downspouts?

Downspouts are the vertical pipes attached to your gutter system that direct rainwater safely from your roof to the ground or drainage system. They are a critical component of any gutter system, helping to prevent water damage to your home’s foundation, siding, landscaping, and more.

Investing in durable materials, correct installation and simple maintenance can save you future costs with infiltrations and structural repairs. After all, a house protected from rain is a house that will stand for decades.

Warning Signs You Need New Downspouts or Repairs
  • Water running down your exterior walls
  • Rust or cracks in the downspout
  • Puddles near your foundation after rain
  • Leaks or water stains in the attic

If you notice any of these warning signs, it might be time to replace your downspouts. Learn more about how to spot failing downspouts to prevent water damage to your home.

Proper Downspout Sizing & Placement

To prevent gutter overflow and water damage, follow these professional guidelines:
Spacing: Install one downspout for every 20 to 25 feet of gutter run (adjust for roof size and slope).
Sizing: Allocate 1 square inch of downspout area per 100 square feet of roof area.
Placement: Position downspouts near valleys or low points for optimal drainage.

Why Are Downspouts Essential?

Foundation Protection: Directs water away from the home’s foundation, preventing cracks, erosion, and costly structural repairs.
Prevent Soil Erosion: Keeps rainwater from washing away soil, mulch, and damaging your landscaping.
Avoid Moisture Issues: Helps prevent mold, mildew, and water damage inside basements, crawl spaces, and around windows and doors.
Extend Gutter Life: Proper drainage reduces stress on gutters, minimizing the risk of sagging, leaks, and blockages.
Improve Safety: Prevents water from pooling around entryways, walkways, and driveways, reducing slip hazards.

Available Downspout Materials & Styles

  • Aluminum: Lightweight, rust-resistant, affordable, and the most common option.
  • Copper: Premium look with superior durability and a lifespan of over 50 years. Develops a natural patina over time.
