Downspout Placement: General Guidelines to Keep in Mind

Proper installation and correct placement of downspouts are crucial to the efficiency and longevity of your home’s gutter system. Otherwise, water runoff cannot be drained properly away from your home, exposing your roof, siding and windows to moisture damage. Moreover, wrong downspout positioning can impact your landscaping and foundations.

In this blog, local roof inspection and maintenance contractor Vista Roofing Inc. shares some of the general guidelines to keep in mind when it comes to downspout placement.

A Downspout for Every 40 Feet of Gutter

One of the many ways homeowners prevent foundation issues is by reinforcing the basement walls. This solution, however, requires a significant budget. With proper downspout placement, you can protect your home’s foundations from potential damage in the most cost-effective way possible. Place at least one downspout for every 40 linear feet of gutter to allow for sufficient drainage. This reduces the threat of overflowing gutters, which contribute to soil saturation and results in basement leaks and foundation issues.

Considering the Roof’s Pitch

Taking the pitch or slope of the residential roofing system into account is also necessary for downspout placement, let alone gutter installation. This prevents water from backing up under the roof covering and inner layers and causing water damage. By directing rainwater away from your roof and other exterior components, you ensure the structural integrity of your home.

The Location of the Downspout’s Termination Point

Proper downspout placement takes into consideration the fixture’s termination point where rainwater is discharged. It should be positioned in a way that water can’t pool close to your home’s exterior walls and foundations. Ideally, the termination point should be near pitched walkways or any similar terrain. You may consider installing a downspout extension if the ground is level and there’s a chance of water backing into your exterior walls.
