When it comes to installing downspouts, there are a few key factors to consider. To ensure proper drainage, it is important to determine the number of downspouts needed, the slope of the roof, and the design of your home. Typically, one downspout is recommended for every 20 to 30 feet of gutters. This will ensure that water flows downward instead of remaining stagnant in the gutter channel.
It is also important to take into account the slope of the roof when installing downspouts. Channels and downspouts must be installed with this inclination in mind so that water flows in the right direction. Finally, you should think about the design of your home. Gutter downspouts should not be emptied near a mezzanine, a basement window, or any other place that could allow water to seep inside.
If possible, place downspouts in discrete places. For gutters larger than 40 feet, it is best to tilt the gutter down from the center to a downspout at each end. Additionally, oversized 3 × 4 inch downspouts are recommended for optimal drainage. The Spoutoff can be installed with new rain gutter systems or can be adapted to current gutters and downspouts that are in good condition.
