Gutter guards are a useful tool that are meant to keep leaves and other debris out of your gutters and prevent clogs. However, gutter guards are an attachment to your gutters and so require installation. So we put together this guide on how to install gutter guards. 

Gutter guards attach to the top of your gutter and work to keep leaves, dirt, and other kinds of debris out of your gutters. Debris can clog gutters and cause water backup, which can lead to structural damage. 

  • Damage Control
    The most important reason to get gutter guards is to prevent potential damage from clogged gutters and water damage. Gutter guards can prevent thousands of dollars in damage by preventing gutter clogs. 
  • Health & Safety
    Clogged gutters can cause water backup, which can cause mold and algae growth. It can also weaken structural parts of your house, which can be dangerous.
  • Pest Control
    Gutter guards can also prevent pests from infiltrating your gutters, such as mosquitoes, wasps, rodents, and opossums. Gutter guards keep standing moisture out of gutters, so they are not a breeding ground for pests. 
  • Saves Money
    Gutter guards can also save money by reducing gutter maintenance needs and preventing damage from blocked gutters. Damage from blocked gutters can cost a lot of money, so gutter guards can save you from those expenses further down the line. 

What to Consider Before Buying & Installing Gutter Guards 

  • Kind Of Gutter Covers
    The most obvious question is what kind of gutter covers you will need. Do you need to keep leaves out or dirt and other granular particles? What kind of leaves do you need to keep out, broad-leaf or pine needles? Keep in mind that most gutter guards do not really help against ice dams.
  • Size Of Covers
    Most gutters measure between 5” to 7” wide. Generally speaking, wider gutters are more common in places that get more rain during the year. Some types of gutter guards will cover gutters of various sizes. 
  • Roof Slope
    If your roof has a slope, then you will need to get gutter guards designed specifically for sloped roofs.
  • Existing Roof And Gutter Conditions
    Roof conditions also determine the kind of gutter guards insofar as how you need to install them.
  • Installation Equipment
    Figure out what kinds of tools you will need to install gutter guards. The kind of tools you need determines whether you will need professional installation. 

Most Common Gutter Guard Materials 

There are three major metals used to make gutter guards: 

  • Aluminum
    Aluminum is very lightweight and is a cheap metal, so it's commonly used for gutter guards. Aluminum does not build up frost easily and is also resistant to mechanical stress and fracturing. 
  • Metal Mesh
    Metal mesh is very flexible and can be fitted around most gutters. Metal mesh is also slightly flexible so it can handle a bit of expansion from ice without damage. 
  • Plastic/Foam
    Plastic and foam gutter guards are cheap but not as effective as metal guards. These kinds of guards filter out most large debris but will leave a lot of needles, leaves, and seeds.

How to Install Gutter Guards: Instructions for Different Types 

The exact way to install gutter guards depends on the kind of gutter guard you get. We put together a handful of installation guides for some of the more common types of gutter guards.  

You will need the following tools to install gutter guards.  

  • Measuring tape 
  • Wire cutters 
  • Ladder 
  • Boxcutter 
  • Screwdriver 
  • Pliers 
  • Power drill (optional) 

Also, before installing any kind of gutter guards, thoroughly clean and drain your gutters.  

1. Brush guards 

Brush guards will keep birds out of your gutters but are not as good as other kinds for leaves or dirt.  

  1. 1
    Measure the length of your gutter line. Make sure to accurately measure corners and bends. 
  2. 2
    Cut the brushes to fit the length of your gutters.  
  3. 3
    Bend the brush wire around the corners and slopes. 
  4. 4
    Make sure the brushes are pressed to the bottom of the gutter and extend the whole length.

Foam guards are another common kind of gutter guard that are relatively easy to install.  

  1. 1
    Measure the entire length of your gutter, including corners and slopes.

Foam gutter guards are very easy to install and are good for leaves and sticks, but they can leave smaller seeds and needles in your gutters.  

3. Mesh guards 

Mesh gutter guards have small holes that let water through while blocking sticks, leaves, and other debris.

    Attach screws if required. 
  4. 4
    Snap the other end of the guard over the gutter or screw it into place. 
  5. 5
    Make sure that the guards are not too tight over the gutter, or else they can bend and damage them.  

4. Perforated guards 

Perforated guards are similar to mesh guards, except that they are made out of aluminum sheets with perforated holes in them.  

  1. 1
    Make sure that the guards you get match the size of your gutters.  
  2. 2
    Place the edge of the guards against the grain of the gutters.  
  3. 3
    Adhere the guards using screws or other adhesives. 
  4. 4
    Cut diagonal pieces out of corner junctions so that they can fit together properly.
