What are the benefits of gutter guards?
Short answer. Good gutter guards keep most leaves and debris out of the gutter, so it keeps draining between cleanings, overflows less, and is less likely to rot the fascia or pull loose under wet debris. They also cut down on ladder trips, mosquito breeding and pests nesting in the gutter, though no guard makes a gutter completely maintenance-free.
The real benefits
- Fewer cleanings: under heavy oak and pine cover in North Georgia, open gutters may need cleaning several times a year. Good guards reduce that to occasional checks and surface brushing.
- Less overflow: clogged gutters spill over the back and front, soaking the fascia, soffit and foundation. Guards keep the trough clear.
- Less weight on the hangers: wet debris is heavy, and guards reduce sagging and pull-away.
- Fewer ladder trips: ladder falls are a real risk, especially on two story homes.
- Fewer pests: standing water in clogged gutters breeds mosquitoes, and debris attracts birds and rodents.
- Downspout protection: guards keep sticks and clumps from jamming downspouts and underground drains.
The limits
- Fine debris such as pollen, oak tassels and shingle granules still passes through some guards and settles in the gutter.
- Pine needles and seeds can lie on top of some styles and need brushing off.
- In very intense rain some styles overshoot, especially reverse curve guards and some screens.
- Guards cannot fix a gutter with bad pitch, too few downspouts, or missing drip edge.
- Guards installed by lifting shingles can damage the roof edge.
Is it worth it?
The value depends on your trees, your roof height, and how often you clean now. Under heavy tree cover on a two story house, guards often pay for themselves in avoided cleanings and fascia repairs. Under open sky they may not. See gutter sizing, seamless gutters and guards and trees and your roof.
