How to Choose the Best Gutter Guards?

The best gutter guards prevent gutters from being clogged by debris. So, do gutter guards work? The answer is yes. These systems have a design that allows water to get in the gutters while keeping debris out. They are instrumental during heavy storms, in the fall season when leaves fall off trees and if your house is in an area prone to such debris as pine needles, leaves, branches and twigs.

Are gutter guards worth it? The answer is again yes. Gutter guards keep the gutters clean, so you never have to keep climbing up a ladder to make the eavestrough cleaning process risky. The best guards will make debris fall off without obstructing water flow into the gutters. The weight of debris and water in clogged gutters can make the gutters collapse. There is also the risk of water spilling over and flooding your foundation and basement. With many types of gutter guards, which one should you buy? This post looks at the pros and cons of popular types of gutter guards.

1. Brush Gutter Guards

Brush gutter guards are cylindrical in shape and have heavy-duty plastic bristles wrapped in steel wire and slide into the gutters. This gutter guard looks like a long bottle brush that is laid inside the gutters. The system works by keeping large debris from entering the gutter while at the same time allowing water to seep through. The installation process is straightforward, thus the reason this system is recommended in DIY projects. The important thing is to clean the gutters before installing the guard and be ready to clean the brush gutter guards frequently.

When appropriately installed, brush gutter guards filter out large debris like twigs and leaves. Since the bristles allow air to circulate, the gutters will remain dry. As a result, the mechanism helps prevent rusting. When cleaning the gutter guard, you simply remove them from the gutters, shake them and place them back in. These gutter guards will save you both time and money. They are very popular and cost between $20 and $300.

What Do Customers Say?

On Amazon, this product has more than 550 customer reviews. It has a score of 4.4 stars, with 85% of customers giving it 4 or 5 stars. While this may seem impressive, the rating is lower than that of other similar products on Amazon.

In most of the reviews, customers were happy with the way the brush gutter guards work. The customers understood that the gutter guard only kept out large debris. Most reviews stated how they had to rinse their guards frequently to remove smaller debris that was trapped in the bristles. A major complaint was that this gutter guard did not work in yards with lots of trees because it got clogged easily by twigs and leaves.

2. Surface Tension or Reverse Curve Gutter Guards

This is an innovative gutter guard made from plastic or metal. Unlike conventional gutter guards, which work by letting water flow through into the gutter, the surface tension gutter guards force water to flow over the gutter, then around a downward curve and into the gutter. This ensures debris never gets in the gutter. Debris simply slides off and falls to the ground. Small debris will at times get in the gutter, but most are easily washed out.

The reverse curve gutter guard works best when the guard has been installed at an angle similar to the roof’s slope. Achieving this is not always possible with long gutter runs since gutters have to be pitched to promote the easy flow of water in the downspout. This means one end of the gutter will hang higher than the other. If the gutter guard is installed on a gutter that is mounted high on the fascia, debris dams may form and allow junk in the gutter.

Reverse curve gutter guards are a lot more visible than other gutter guards. They are harder to install, especially on a steep roof. Other than that, they work great in keeping most debris out.

Surface Tension or Reverse Curve Gutter Guards

  • Made from moulded plastic or lightweight metal

  • Very visible from the ground
  • During heavy downpours, water can shoot over the gutter guard
  • Might not be ideal for tile, steel, wood and slate roofs

3. Mesh Gutter Guards

Mesh gutter guards are similar to screen gutter guards. They are made of plastic or metal and have tiny holes which allow water to sink into the gutter while keeping debris out. These gutter guards are usually installed by slipping them under the bottom row of the roof shingles, attaching a fastener to the fascia, or snapping onto the gutter.

While they work great in keeping the gutters clear, when compared to screen guards, these guards are a lot more expensive and harder to install. They have smaller holes that prevent more debris from getting in. It is good to note that some variety of the mesh guards are flimsy and are easily damaged by harsh weather.

What Do Customers Say?

More than 2,500 customers on Amazon have reviewed this product. The product currently holds a 4.6 Stars rating, with 92% of customers giving it 4 or 5 stars. Satisfied customers reported that the product was easy to install thanks to the instructions, surplus of screws and drill bit head that was included in the packaging. The holes in the mesh gutter guard were the main complaint. Customers said the small holes could not allow water to get through during a heavy downpour. This caused water to spill over instead of getting into the gutters.

4. Micro or Fine Mesh Gutter Guards

These gutter guards are similar to the mesh guards, with the only difference being they have smaller holes that help keep more debris out. They work like screens. The tiny holes of the mesh don’t clog with needles and seeds, but they may fill with tiny particles such as shingle grit. As a result, these gutter guards require occasional cleaning. Unlike screen guards, the fine mesh gutter guards are easy to brush or blow clean.

Micro-mesh gutter guards can be installed under shingles during installation, or you can bend the back and screw it to the fascia. The installation method helps strengthen the gutters and enables them to hold up under ice and snow avalanches that are common on steel roofs.

You should take note that products made using window-type screen materials get damaged easily by branches and snow. So instead, go for those made of hard surgical stainless steel.

Customers were also happy with installing these gutter guards, thanks to the inclusion of screws, drill bit head, and instructions. While the holes may be clogged by shingle grit, customers applause how easy it is to clean the mesh. Most complaints are on how water can spill over during heavy downpours without getting into the gutters.

5. Foam Gutter Guards

Just as the name implies, foam gutter guards are made of foam. They are triangular blocks that sit in the gutters. Their work is to block debris from getting into the gutter while allowing water to pass through the porous composition.

The best thing about foam gutter guards is that they are effortless to install. You don’t need a professional to help with the installation. The gutter guards come in small sections, which makes inserting them in the gutter system easy. You can also cut the blocks to fit any corner section. Since the foam gutter guards sit inside the gutter system, they cannot be seen from the walkway or street. They remain hidden and thus will not impact the aesthetics of your home.

While they work great in keeping debris from getting into the gutter systems, these foams have one major drawback – they can be saturated with water in wet climates. Over time, the water saturation may create mould, mildew or rot. You have to replace the foam gutter guards if you notice any of these issues. Foam guards are also not great for keeping pests out. Pests can easily burrow in the foam and create a nest.

All in all, foam guards are very affordable and readily available in local and online stores. However, although they are cheaper than other types of gutter guards, they have to be cleaned and replaced frequently. All the same, they are an excellent option for homeowners that are on a budget.

Most customers state that they purchased this product because it is effortless to install. There is no need to bring in a professional or spend hours getting it installed. You only need a ladder, and within a few minutes, you are done. On the flip side, customers complained about how easily the foam got soaked with water. Others said it got filled quickly with tiny pieces of debris, thus requiring frequent cleaning.

H2:  6. Screens Gutter Guards

Screens have, for years, been the most common types of gutter guards. They are available in various shapes and are made of a variety of materials. You can install screen gutter guards in one of many ways. These products work best where leaves are the main issue. It is good to note that the openings in the screen are big enough to allow pine needles and seeds in. Cleaning the screens often requires removing them from the gutters. There is also the fact that the screens can get plugged, and cleaning them is not easy since some debris can be entangled in the screen, making it hard to brush or blow them off. The same screens are easy to install with some sliding easily under the shingles.

 What Do Customers Say?

Screen gutter guards have very favourable customer reviews. These guards have relatively high customer review scores on sites like BBB, Yelp and Amazon. In most reviews, customers praise the ability of the gutter guard to keep large debris like leaves, branches and twigs from getting in the gutters. However, some customers are dissatisfied with the screens’ ability to keep smaller debris out. For example, customers reported that the gutter guard collected debris and trapped pine needles in the holes. This forced them to clean the gutter guards more frequently than they would love; in fact, some report cleaning their gutter guards several times a year. Other customers complained that it is easy for valleys to form on the screen causing more debris to collect and others to get trapped in the spaces.
