这Best Gutter Guards of 2021

这A-M Aluminum Gutter Guards are an excellent backup choice if our top pick is unavailable. The design is very similar, with a simple all-aluminum construction, though it fastens to the front of the gutter and rests on the back of the gutter instead of using screws on both sides. It does have nice tabs so that two pieces can fit together seamlessly without creating gaps, but we prefer the gutters that have screws at the back at well, which did a better job resisting buckling than this model.

Everything else about the A-M gutters was exceptional: They are easy to install, very easy to cut, affordable (at the time of testing they cost right around $1.20 per linear foot), and they look great. They don't come in the same range of colors as our other gutter picks, if that's something you care about, but they are available for both 5-inch and 6-inch gutter widths and work with a wide range of gutter designs.

In our long-term testing, these gutters excelled. They handled everything from rain to wind to snow without issue, and they didn't allow any debris to clog up the gutter that we could find while checking periodically.

这LeafTek Gutter Guard system is one of the most popular that we found, and it definitely lives up to that billing. Though it's not the best gutter guard we tested, it was easy to work with, lightweight, durable, and affordable. It is a tad more expensive at most lengths than the top picks we tested, though the prices of aluminum (and thus these all-aluminum gutter guards) are variable and that can change.

Overall, it's a quality product that is worth the investment, though it did seem a little flimsier at the seams and the vented ridges weren't as tall as on other gutters. That said, it didn't have any issues in our long-term testing with debris or clogging. It is available in white and black, with enamel coatings for both, and it comes in lengths ranging from 32 feet up to 200 feet at about $1.50 per linear foot. Like our top pick, it comes with a range of hex-head self-tapping screws that were able to easily drive into the existing gutter and will be easier to remove later, even if they were to rust.

这Smart Screen gutter guard system earns high marks for ease of installation and its ability to block debris. They are more like gutter covers that can be screwed in place, with heavy-duty aluminum that wraps over the front edge of your gutter. The instructions aren't particularly intuitive, but it was easy enough to install.

My main issue with these is they allow water to pool up too easily, which could contribute to freezing or ice damming eventually. They were simple to use and are not terribly expensive at around $1.50 per linear foot, but with better products on the market these are tough to recommend.

Raptor不锈钢微网是一种独特的排水沟护罩类型，它使用了编织不锈钢的重型网眼，让水渗透，但没有任何碎屑。绝对比瑞士奶酪风格的后卫阻止所有可能进入排水沟的所有东西绝对更好，但是我发现安装程序非常棘手，它们几乎是每条线性脚2美元的昂贵两倍，而清理它们可能会很麻烦。

这basic installation of these, like other gutter guards, was pretty simple. It comes with self-tapping hex head screws (and a magnetic drill bit, a very nice touch), and you're meant to pop these into place and then fasten them down. It goes smoothly enough, though the micro mesh can pretty easily cut your skin if you're not careful.

这installation guidewas refreshingly simple with very clear pictures and diagrams. The one thing I took issue with is the recommendation to potentially pop these under the last row of shingles. It doesn't specifically mention this, but I would have real concerns about that causing ice dams in freezing climates, driving frozen (and eventually thawed) water right back into your home. The guide presents plenty of alternative arrangements though, so it's not a requirement.

这里的主要好处是微网,它很快就会回来的l keep out more debris than our top picks. If you're using a rainwater catch system and you want to prevent anything and everything from getting into your basin, this may be a good alternative, but for everyone else our top picks are a better value.

这Amerimax "Snap In" Gutter Guard promises a dead-simple installation that doesn't require any screws at all. These are lightweight, affordable, mesh-style guards that are made primarily of plastic. They're meant to just pop into your gutter, using the size of the guard and the gutter to create the tension to keep them in place.

根据我们的经验，这些只是没有承受任何重大的重量。即使是我们使用软管的基本倾盆大雨测试也使它们略微扣紧，留下叶子和针的开口可能会流入。它们可能会减慢您的排水沟的堵塞问题，但不会解决它们。它们的价格不足，每线性英尺不到1美元，但节省不值得麻烦。

这Frost King plastic gutter mesh promises a simple tool-free solution to your clogged gutter woes, but it just doesn't hold up. This is little more than a roll of plastic mesh that you bend and place in your gutter. It will generally do a half-decent job of keeping large leaves out and letting water pass through, but it's barely able to keep any sort of pine needle or small leaf debris out in our experience.

这里的主要问题是，这无法承受任何重大的重量。尽管并不是每个人都得到我们在新英格兰的积雪，但甚至不仅仅是轻量级的叶子，而且护卫队开始屈服。它们的安装简单易于安装，非常实惠（测试时每线性英尺不到$ 0.50），但是除非您的需求受到极大的限制，否则这些可能不会坚持。

Amerimax“锁定”地沟警卫是另一个esh-style guard but these are just sections of open mesh shaped to fit your gutter instead of the kind that screw into place. They are very easy to install, though the lack of fasteners can be annoying as pieces slide around while you go from section to section (try a coat hanger for a little extra reach if you are on a ladder).

In general, they seemed to work well. They didn't block the pouring rain much at all, but they did keep most of our test debris out. The main issue I had with these is they install by fitting up under your shingles. This isn't as dangerous with the mesh-style guards because water shouldn't pool and freeze on top, but it still presents a huge problem if, like me, your gutters weren't professionally installed. Since I have sections where the shingles hang up to 3 inches over the gutter, this type of "lock-in" installation is basically impossible.

E-Z天沟护卫在网上非常受欢迎，对于希望在周末安装后卫的DIYER来说，它们似乎是理想的解决方案。不幸的是，我没有发现它们很容易使用，并且构建质量并没有使我充满信心。

Though these guards handle the basics just fine (they're easy to install, cost around $1 per linear foot, and kept most debris out and water in), they just don't seem likely to hold up to punishing winter climates. The mesh is among the strongest that we found that has such large openings, but we did find that pine needles could slip through and the guards were prone to sliding and creating gaps near the ends and in the seams, which could eventually lead to clogging.

If regular gutter guards seem boring to you, these "Superior" Gutter Guards feature a patterned raise stainless-steel mesh design that looks great. Unfortunately, they were difficult to work with, didn't install easily, and the mesh gave me one of the nastier paper cut-style slices I've had. They are also expensive, costing nearly $2 per linear foot—about as much as a professional installation in some places.

This product may be different, but having marginally better-looking gutters (that will get filthy with time anyway) isn't worth the price.
