Residential Gutters – Part 3

Proper Pitch
Gutter installation should follow a couple basic rules. Gutters must be pitched so water will flow to the downspouts. The rule of thumb for this slope is a vertical 1/2 inch for every 10 feet of horizontal run. If the run is more than 35 feet long, some specialists recommend installing the high point of the system in the middle and sloping the gutter downward in both directions to downspouts on both ends of the run. Water exiting the downspout must always be directed away from the foundation.

Gutter Add-Ons
The gutter industry has seen an explosion in the accessory side of the business. Screens, barriers, and other devices used to keep foreign objects out of the gutter are literally everywhere. When considering such accessories, homeowners will want to evaluate the types of debris that may land on or in their gutter. “Homeowners will want to consider everything from the number of trees to the types of leaves,” says Milliman. “Will there be whirlybirds, or pine needles?”

Hybrid products that combine solid hoods with screens exist, as do the more recent gutter foam products like Gutter Stuff and GutterFill. These foam products actually fill the length of the gutter, allowing water to run through and drain while keeping solid objects out. Additionally, homeowners may look into splash blocks on the ground that guide water away from the foundation or “rain chains” that replace traditional downspouts with Japanese-themed decorative links or chains. Rain chains are aesthetically pleasing, and come in a number of design options.
