Is a gutter guard any good?
Short answer. A good gutter guard is worth having on most Georgia homes with trees nearby: it keeps downspouts open and turns several cleanings a year into a light brush-off, for decades in the case of stainless mesh. A poor one, such as foam, brittle plastic screens or anything tucked under the shingles, often costs more in hassle than it saves.
What owning a good guard looks like
- Year one. Gutters stay open through leaf season. You brush pollen and tassels off the surface once in late spring.
- Year five. Still a brush-off once or twice a year. A yearly peek under one panel near each outlet shows only a thin layer of grit. Downspouts have not clogged.
- Year fifteen. Stainless mesh and aluminum frames are still intact. The guards may come off and go back on for a roof replacement, which is a normal part of their life.
What owning a poor guard looks like
- Foam. Seedlings and packed grit by year two or three; pulled out and thrown away.
- Plastic screens. Brittle and sagging after a few summers; needles stuck in every opening.
- Hood systems under steep roofs. Water shooting past the gutter during thunderstorms; needles collecting inside where they cannot be seen.
- Under-shingle installs. Lifted shingles and broken seals along the first course, which can let wind get under the roof edge.
How to tell good from bad before you buy
- Fine stainless mesh on a rigid frame, not plastic or foam.
- Fastened to the gutter lip and back edge or fascia, not under the shingles.
- Made for your gutter size, with a plan for corners.
- A warranty that states what it covers, and an installer who checks the gutters first.
- No promise that you will never clean again.
If your gutters are undersized or failing, fix that first; even the best guard cannot make a small gutter carry more water. See gutter sizing and guards and pine needles and leaves on the roof.
