What is Gutter Guard?

Gutter guards serve as a protection system for your gutters. They’re used to keep things out of your gutters. These guard pieces attach overtop of your gutters. They stop and prevent your gutters from clogging and overflowing. They can prevent damage not only to your gutters but also your landscape, roof, and foundation. They’re supposed to allow for less frequent gutter cleanings. This means you can go longer periods between gutter cleanings. They’re also used to protect your gutters and help them maintain their lifespan. The protection causes gutters to rust and rot slower than normal. There are many different types of gutter guards. They vary in prices, materials, shapes, and sizes.

What Gutter Guard Should I use?

According to a licensed home inspector, four types of guards are easiest to install. All four are common in the gutter guard industry. The different materials offer different levels of simplicity, but they’re all doable. Each type of gutter guard also has both pros and cons to take into consideration. So, what’s important to know about each gutter guard?

Types of Gutter Guards

  • Micromesh- Mesh system gutter guards are one of the most popular choices. They have a simple design, two strips of material with a fine mesh between them. The mesh keeps debris out. Micromesh gutter guards work well with existing gutters. An installer would only have to slip one end under the shingle. The other end attaches to the outer edge of the gutter. You can also curl the mesh into an L on one end and screw it into the fascia under the roof. The other end would slip into the gutter for a tight fit. Different types of mesh guards have different fineness. You can choose what works best for cleaning your gutters.
  • Brush Inserts- Brush inserts are one of the least complicated gutter guards you can use. They have two components: a stainless-steel wire spine and polypropylene brush filaments. These filaments can withstand any weather condition. You can install these inserts yourself. All you need is to get the right fit and lay the inserts inside your existing gutters. The filaments keep debris out, allowing only water to pass through. In principle, it sounds easy. It’s not always as easy as it sounds though. These accumulate finer particles.
  • Screen- These are a stronger, more perforated version of mesh gutter guards. They come in aluminum material and a variety of styles. Styles include:
    • K-Style Drop-In screen guards
    • K-Style Lock On-screen guards
    • K-Style Hinged screen guards
    • Half Round Hinged
  • Reverse Curve- Water runs down the roof towards the gutter. It slides off the top, flows down the bend at the edge, and spills backward into the gutter. The bigger leaves get washed down to the ground. Surface tension directs water into the gutter and down the downspout. They don’t filter the debris to keep them on the gutter guard. They direct as much water with as little debris as possible. Most reverse curve gutter guards have a ⅜ inch opening for the water. They can take up to 22 inches of rainfall at a time – which is plenty more than you’ll need in the US.

The Downsides of Each Type

  • Micromesh- Both installation styles have flaws. The under-shingle micromesh has an angle that makes water glide over the gutter. It travels down to the foundational edge of the house. Over time, it will erode that area or even cause some flooding. The second installation style, where the guard is flat, tends to leave the leaves bulked on top of the mesh. Finer particles clog the tiny holes, forcing you to bring out the power washer to clean the mesh.
  • Brush Inserts- They’re easy to manage, but they will still accumulate finer particles. Also, they don’t keep out tiny twigs, seeds, or pines. You’ll still have to take the inserts out and clean out the gutters.
  • Screen- Screen guards gather bigger debris over a shorter time compared to micromesh. Buildup of debris can make the gutters heavy. This can destroy your roof and put the entire gutter at risk. Screen gutters installed under the shingles can void the roof’s warranty. It distorts the roof.
  • Reverse Curve- Reverse curve gutter guards are notorious for ice dams. You lift the shingle at an angle when you install them. Water on aluminum freezes quick. This turns the water underneath the shingle into icicles. They’re not 100% effective in keeping the rainwater in and the debris out. They also are the perfect spot for insects and plants. They provide shade, dirt, and a wet spot. Plants will likely take root there if seeds germinate. Insects such as bees and wasps will make their colonies in that space.

    You’re absolutely right that clogged gutters can lead to a range of problems, from unsightly stains on your siding to more serious issues like foundation damage and pest infestations. That’s why we recommend having your gutters professionally cleaned at least once a year, or more frequently if you have a lot of trees near your home.
