Downspouts

Directing Water Away from your Home & Business

The only thing worse than not having gutters, is to have gutters that collect all of the water off the roof, only to direct it to one spot at the foundation.

The water gathered by the gutter system should be discharged from the downspout, and directed three to four feet away from the foundation (provided that is far enough to keep the water from flowing back to the foundation). This can be achieved by using, downspout extensions, concrete splash blocks (not plastic), and underground piping. Additional alternatives include, positively sloped concrete surfaces or appropriate landscaping solutions.

Residential & Commercial Downspouts

Residential downspouts come in 2” x 3”, 3” x 4”, or 4” x 5” options. With proper maintenance and cleaning, downspouts will remain serviceable for many years. The most common reason for changing out downspouts is to upgrade the downspout size to reduce maintenance requirements, and improve efficiency. Other reasons include:

  • Rusted out components
  • Ice split seams
  • Damage
  • Outlet location changes
  • System design changes
  • Color changes
  • Extensions

Downspout Maintenance:

Maintenance is all about regularly keeping the gutters, and downspouts, clean. We generally recommend that gutter systems be cleaned once or more a year, depending on conditions. Plugged up gutter systems cause water to get behind the gutter, resulting in damage to the exterior finishes of the structure. Be preventative; don’t wait for the problem to occur – keep the problem from ever happening!

Interior damage is common during winter months when clogged gutters cause ice dams. Ice dams can weigh hundreds of pounds and, if not taken care of, they can rip the gutters right off the structure. This is a serious problem on un-pitched gutter systems, and especially on those installed with the inferior spike and ferrule system. Don’t wait for your gutter system to come crashing down – the time for maintenance is now!

The larger (3” x 4”) downspout drains approximately 1.5 times faster than the standard (2” x 3”) downspout, which drains 7.2 gallons of water per second. The larger downspout will drain approximately 1,170 square feet of roof area. As opposed to the standard downspout, that will only drain about 770 square feet. This is 33% difference; it could be the difference between hassle-free upkeep, and costly repairs in the future. Additionally, the larger downspouts are practically self-cleaning because they do not clog up, or freeze, as easily as standard options.
