How To Install Gutter Guards On A Metal Roof

Metal roofs are known for their many benefits, but they can still have problems. One common metal roof issue is caused by the gutters. Over time, they can clog with leaves, debris, and other materials, leading to water damage, rust, and expensive repairs. The good news is that gutter guards provide a simple yet effective solution for this problem.

By installing gutter guards, you can reduce the need for frequent cleaning and extend the life of your gutters. While it might seem like a challenging task, it’s easier than you might think. In this step-by-step guide, we’ll show you how to install gutter guards on a metal roof and keep them in top shape.

Why Do Metal Roofs Need Gutter Guards?

To manage fast-moving water and debris, metal roofs need gutter guards. Without them, gutters can clog, leading to water overflow and possible damage to the roof and foundation. By keeping gutters clear, these guards improve drainage, reduce maintenance, and help protect the home from water damage.

Different Types of Gutter Guards for Metal Roofs

Now that you know why they’re needed, let’s go over the different types of gutter guards and how they protect your metal roof:

1. Screen Gutter Guards

Made from durable aluminum or steel mesh, screen gutter guards block larger debris like leaves and twigs while letting rainwater flow into the gutters. However, they may struggle with smaller debris, such as pine needles, which can slip through the holes.

2. Mesh Gutter Guards

Using a fine metal mesh material, mesh gutter guards offer better protection by blocking both large and small debris, making them a reliable and versatile option.

3. Micro-Mesh Gutter Guards

With ultra-fine mesh, micro-mesh gutter guards prevent tiny debris, like shingle grit and small leaves, from entering the gutters, ensuring smooth water flow and low maintenance, especially for metal roofs.

4. Reverse-Curve Gutter Guards

Designed with a curved surface, reverse-curve gutter guards direct rainwater into the gutter while allowing debris to slide off, making them ideal for areas with heavy rainfall.

5. Brush Gutter Guards

These guards use bristles to block larger debris while letting water pass through. Though effective, they may require more frequent cleaning to prevent buildup.

6. Foam Gutter Guards

Lastly, foam gutter guards fit snugly into the gutter, blocking debris and allowing water to flow. While simple, they can clog over time and may not be as durable as other options.

How To Install Gutter Guards On A Metal Roof

After choosing gutter guards for your home, it’s time to install them. Here’s the step-by-step installation process for mesh gutter guards:

Materials and Tools Checklist

MATERIALS	TOOLS
Gutter guard mesh (matched to your roof color)	Drill with appropriate bits
Trims (matched to gutter and fascia color)	Small brush for cleaning
Saddles	Hose
Screws	Shears or tin snips

Pre-Installation Steps

1. Clean Your Gutters

Start by cleaning your gutters to remove debris like leaves and twigs, using a brush or your hands (wear gloves for protection). After clearing out the debris, flush the gutters with water to ensure they flow properly and identify any areas needing repair. This step is essential before starting your gutter guard installation.

2. Measure Your Gutters

Once your gutters are clean, measure the sections where the guards will be installed. Be sure to add 10 to 20 inches for overlap at the ends. This guarantees a snug fit when it’s time for the installation, so the mesh covers your gutters completely.

3. Cut the Mesh

With your measurements in hand, roll out the mesh on a flat surface. Cut the mesh to size, leaving extra length for overlap. 

Installation Steps

4. Fix the Gutter Guard to the Gutter Edge

Start by positioning the trim along the outer edge of the gutter so that it sits flush against both the gutter and the roof. Secure the trim with screws every 10 inches. This will keep it in place before you install gutter guards.

5. Secure Mesh to Roof

Attach the mesh to both the trim and roof using screws and saddles. This will secure the mesh firmly in place, ensuring gutter guards are installed properly.

Final Checks

Finally, after the gutter guards are installed, run water through the gutters to check for proper flow. Make any necessary adjustments so your gutters are functioning at their best, keeping your roof and foundation protected.

Common Mistakes to Avoid

To make the most of your efforts, avoid these common mistakes during installation:

1. Installing Guards Too Loosely

Make sure the guards are tightly secured. Loose guards allow debris to slip through and clog the gutters.

2. Over-tightening Fasteners

Tighten screws just enough during gutter guard installation. Over-tightening can damage the metal roof or gutter system, leading to leaks.

3. Neglecting Water Flow Check

Always test the water flow after installation. It’s easy to miss issues, but a quick test can help catch problems.

Maintenance Tips for Gutter Guards on Metal Roofs 

To keep your gutter guards in great shape, follow these easy maintenance tips:

1. Regularly Inspect the Guards

Check your gutter guards every few months to make sure they’re clear of debris. Even with guards, leaves and particles can build up.

2. Clean the Guards

Clean guards with a garden hose or soft brush. Avoid using a pressure washer, as it can damage the mesh or screen during gutter guard installation.

3. Check for Rust or Damage

Inspect for rust or damage, especially where the gutter guards attach to the gutter. Metal roofs and gutters are exposed to the elements and can wear over time.
