Will Gutter Guards Work Against Heavy Rain?

Gutter guards are safe to use on your home to protect your property during a heavy rainstorm. A guard is a cover that works over your existing gutters to prevent solid items and debris from entering your gutter.

The guard will collect water as it moves off your roof and into your gutter. Outside debris will slide off the guard and prevent it from adding excess weight. The guard will also ensure the water that comes in during a storm stays together, preventing splashing and undue stress.

Choosing a Rain Guard Gutter System

Material and Durability

You can find gutter guards made with one of many materials. Aluminum is a common compound that is lightweight and can handle intense stress. You could also use a stainless steel micro mesh item that can last for a while. Plastic and foam guards are also available and can appear in many shapes, but they are fragile.

Roof and Gutter Configuration

You need to find a quality gutter guard that fits your roof and your gutter layout. Most gutters use a straight design, but some may come with curves. You have to utilize a more specialized guard layout if there are curves. You should also factor the slope on your gutter, as that might influence the installation process.

Gutter Width for Water and Air Flow

Gutters come with widths from four to eight inches. Most rain gutter guard systems can support bodies up to six inches wide.

The gutter should be wide enough to allow air to move and to ensure water can flow without adding excess stress in a small space. Adding a guard over a tight space is a worthwhile move.


A gutter guard should blend in with the rest of your roof. The guard may feature the same color as the rest of the gutter layout. It may also fit directly inside the gutter and not show from the outside.

Ease of Installation and Maintenance

You can install most shields by drilling them to the fascia above the gutters and below the roof.

Some models require you to insert the end part of the guard body under the tiles at the end of your roof. You have to choose a format that is easy to install.

You should also watch for how you can maintain your guard. Some guards may feature small openings that you have to check on occasion. While it is easier to clean gutters with guards than to do the same without them, it can still be challenging to manage.


You should find a good value for the money when finding the best gutter guards for heavy rain. You can expect to spend from $7 to $10 per linear foot. Since an average home has about 200 feet of gutter space, you could spend at least $1,500 for a gutter guard.


You should have a warranty that will provide peace of mind when you purchase your gutter guard. Some warranties last for a year, while others may last for twenty or more years.

Some warranties are also transferrable, meaning they will be intact even if someone else acquires your property. A transferrable warranty can increase a property’s resale value.

Best Gutter Guard Type to Protect Against Heavy Rainfall

Many gutter guards can secure your home against heavy rainfall. But a micro-mesh guard is best for when you’re trying to find something that protects against heavy downpours.


A micro-mesh guard features small openings and has enough vents to allow rain to move through the entire gutter without favoring one space. The mesh features interwoven fibers that allow rain to flow while keeping debris from sticking.

Large Screen

You could also use a screen guard system with several holes around the body. The holes allow water to flow through the top. But the water may still accumulate on top while waiting for openings for the rain to flow through.

Reverse Curve Guard

A reverse curve guard features a solid body that provides a cover over most of the gutter. The curve allows debris to slide off, but the small opening allows rain to move through. It is ideal for light rainfall, but it may become overwhelmed during an intense storm.

Rain Gutter Guard Pricing Guide

Rain gutter guards cost about $7 to $10 per foot on average. You could spend about $200 or more on 25 feet of coverage.

Your gutter guard's total value will vary based on the length of the system and whether you hire someone to help. Professional installation may cost a few dollars extra for each foot you utilize.

Tips For DIY Installation of Rain Gutter Guards


You will need to review the instructions for how to install a gutter guard or cover. You can secure your guard in one of three ways:

  1. 1
    Some guards fit directly inside the gutter body.
  2. 2
    Other models may require you to drill some holes into a gutter and the fascia wood near the gutter and roof.
  3. 3
    You might need to slip a guard under your roof tiles in some cases. Such an installation may void your roof warranty, so check the terms of your warranty before you start.

You may require a few screws and a power drill to help you secure the guard. Most gutter guard products come with the screws you need for the task.

You may also trim some parts of your guard for a custom fit if you wish. The point is valid when you have small spaces or curves to cover.

Safety Measures

Be sure you wear safety gloves and goggles when installing your guards. You should also have another person ready to secure your ladder while in use.

Do not attempt to install your gutter guards when it is windy outside. Avoid setting a ladder on an unstable spot, as it could slip if you are not careful.

Measuring a Guard

You can measure your gutter width to see what size you should have for a guard. You should measure from the top of the back where the gutter connects to the outside edge to figure out the width. You can also measure the length by checking individual parts of your gutter to see what works
