Get Your Money Out of the Gutter
That leaky, leaf-collecting roof accessory can be mean more than an autumn ladder-balancing act

When buying or building a home, few homeowners take the time to investigate (or interrogate) the gutter. Here are some gutter tips from Dalyn Walters, the director of marketing for Senox Corporation, a gutter manufacturer based in Austin, Texas.
1. Make sure the gutter doesn't hold water. Sounds simple, but Walters says many gutters are installed poorly and don't drain to the downspout. Accumulating water can become an insect breeding ground and cause problems to the roofline and fascia board. To test gutter drainage, simply get a ladder and hose and run water into the gutter. If it pools, there's a problem.
2. Check for downspouts. Architects and engineers often forgo drainage in key areas of the house, Walters says. Be sure to look for downspouts in the front.
3. Don't mix metals. Trying to cut corners by putting an aluminum end cap on a steel gutter will cause corrosion where the two metals meet.
4. Thickness doesn't matter. Gutters come in several different gauges. The .023 gauge is the standard in South and Midwest, while the thicker .032 gauge is popular in the Northeast and Rockies. Homeowners in these snow-and ice-heavy areas think it adds strength to their gutters. Not so, Walters says. Gutter strength is truly determined by placement of the gutter hangers. Placing hangers one-and-a-half feet apart rather than the standard two feet makes a gutter much stronger than putting a larger gauge on the same amount of support.
5. Look for a drip edge. The drip edge, or drip cap, is a metal strip that sits underneath the shingles in order to extend the surface of the roof over the gutter. Without one, water can leak into the plywood. Walters says that although it is in building code for all homes to have a drip edge, they are still not widely accepted everywhere.
6. Leaf guards are not miracle workers. "Don't believe the hype," Walters says. "The simple fact is that anything on the exterior of a home needs maintenance." No matter what gutter guard you get, Walters says you�re going to need to re-caulk and clean debris out of the corners. Some systems won't even let you get your hands inside. If you insist on getting a guard, Walters recommends a powder-coated mesh or galvanized screen that only lets in debris small enough to be washed out by a hard rain.
