By Britt Olizarowicz

A flat roof can give a unique and modern look to a home, but when it comes to debris getting stuck on the roof there are typically some issues. Luckily gutter guards are going to make the process of cleaning and maintaining a flat roof considerably easier. In our guide featuring the best gutter guards for flat roofs, we provide:

  • The manufacturers with the best gutter guards for flat roofs
  • How much gutter guards will cost
  • If gutter guard installation is worth it
  • And much more

One of the most important things that homeowners with flat roofs must understand is that a sloped gutter guard installed at the same slope as the roof is not a great solution for flat roofs. Instead, guards that attach to the gutter or slide under the first row of shingles make the most sense. Let’s look at the best gutter guard for your home and how you can help maintain the health of your flat roof for years to come.

To see the current pricing of this Raptor gutter guard, look on Amazon.

6) GutterStuff Foam Gutter Guards

GutterStuff Foam Gutter guards are the best foam gutter guards for a flat roof. Foam gutter guards are very simple to install and will not require a professional to complete the project. In addition, the GutterStuff Foam Gutter Guards will have a lower price per linear foot than some of the major gutter guard providers on the market. GutterStuff guards allow water to penetrate the foam, but all the other debris will sit on top of the foam insert. With GutterStuff Foam Gutter Guards, you will still need to clean the top of your gutters from time to time, but nothing will fall down into the gutter.

The installation process is much easier than other guards as you will simply cut pieces into place and slide them directly into your gutters. When looking at the budget-friendly gutter guards, foam style guards tend to be a better option than brush gutter guards. With the amount of debris that will pass through the guards, the bristles will continually be coated in leaves and debris without this foam protection in place.

Key Features

  • 15 years of proven performance
  • Easy installation
  • 5-year warranty
  • 4, 5, or 6-inch width options
  • 32, 96, 144, or 192-foot length options.

What Customers Are Saying

GutterStuff Foam Gutter Guards have very fast installation and more than 15 years of industry experience. These are all strong positives that have helped GutterStuff earn 4.4 out of 5 stars on Amazon. There were more than 100 reviews collected, and more customers are very happy with the overall functionality of their GutterStuff foam gutter guards. Of course, there were some issues with overall waterflow, but this was to be expected.

If you live in an area with very heavy rains, you may see water flow over the top edge of your gutter from time to time. The foam material being somewhat dense does not always allow a large amount of water to flow through the guards. In addition, debris is known to sit on top of a foam gutter guard, and sometimes it will stick to the foam material. This tends to be a problem with pine needles and other sharp debris sticking out of the top of the gutter. A few cleanings a year should fix this, but keep it in mind as you shop for a gutter guard solution.

Buying Guide for Gutter Guards for Flat Roof

We hope you now feel you can choose the type of gutter guard that will work best for your flat roof. The flat roof can be a challenge sometimes as both large debris and small debris tend to get caught in the gutters. However, with the right gutter guards installed, you should have no issues getting the roof cleared off without having to simultaneously clean the gutters. Here are a few things to keep in mind while shopping for the best gutter guards for a flat roof.

Quality

The highest quality gutter guards are the stainless steel mico mesh guards. These guards are known for their ability to keep any type of debris out of the gutters and ensure the best possible water flow. Those that make the investment into micro-mesh gutter guards have noticed fewer issues with debris buildup and damage around the foundation of the home. One of the signs of a high-quality gutter guard is the length of a warranty and the materials used. Vinyl, foam, and brush gutter guards are not as high quality, but they can be better from a cost perspective.

Cost

The cost of a gutter guard will vary depending on the size of your home, the type of gutter guard you choose, and whether or not you need professional installation. Some gutter guards are less than 50 cents a linear foot, and others will be well over $4 per linear foot. The key is finding a solution that works for your budget and protects your gutters. Make sure to talk to your gutter guard representative about any hidden costs or issues with the compatibility of your current gutters.

Installation

Gutter guards are installed by a homeowner or a professional. The professional installation is more costly but typically results in homeowners having a more extended warranty. The DIY installation will save you money but will cost more of your time. Depending on how the gutter guards are installed, there can be complications with functionality, especially on a flat roof. If you do not have home improvement experience, the DIY installation is not recommended.

Appearance

With a flat roof, it is essential to choose a gutter guard that will blend in with the color, style, and design of the current home. Flat roofs come in different types of materials, and most gutter guards are compatible with both metal roofs and shingle roofs. The custom color options from many gutter guard manufacturers are typically available in sample size. We highly recommend looking at a sample before ordering the entire batch of guards for your home.

Size Options

Gutter guards are available in a wide range of lengths. Some manufacturers make 4-foot sections while others choose longer 8-foot sections. The width of standard gutter guards is typically 4, 5, or 6 inches. The commercial sizes are 7 or 8 inches. Companies like LeafFilter Gutter Guards will make custom gutter guard sizes for the customers that need them, but this will come at an increased cost. Overall, gutter guards will be standard in size, and they match the sizes of most standard gutters.

Warranty 

The warranty for gutter guards can range from one year to a lifetime. The lifetime transferrable warrant is the best solution for most homeowners and will ensure you are only paying for gutter guards one time. Professionally installed gutter guards are more likely to offer the longest warranty, while the DIY guards have a shorter warranty. In addition, stainless steel micro-mesh gutter guards have a longer warranty than most others on the market because of their impressive material.
