Gutter guards reduce the amount of debris that enters your gutters, cutting down on cleaning frequency and helping your system drain properly. Several types of guards are available, and installation methods vary depending on which style you choose. This guide covers the installation process for the most common gutter guard types.
Types of Gutter Guards
Before installing guards, you need to select the type that suits your situation and budget.
Mesh Screens
Mesh screens cover the gutter opening with a metal or plastic grid that blocks leaves while allowing water through. Fine mesh versions with smaller openings also block pine needles, seeds, and shingle grit. Mesh screens are affordable and work well in most environments.
Solid Covers
Solid covers, sometimes called reverse curve or surface tension guards, have a solid top with a curved edge. Water follows the curve and flows into a narrow slot while debris falls off the front. These guards handle heavy rain well but may allow small debris to enter.
Foam Inserts
Foam inserts sit inside the gutter channel. The porous foam allows water to pass through while blocking debris. Foam guards are inexpensive and install quickly but require replacement every few years as the foam degrades.
Brush Guards
Brush guards consist of bristles arranged in a cylinder shape that sits inside the gutter. Debris rests on top of the bristles while water flows around them. Brush guards install in minutes and work well for large leaves but may not stop smaller debris.
Micro-Mesh Guards
Micro-mesh guards use a fine stainless steel mesh over a support frame. The tiny openings block virtually all debris including shingle grit. These guards cost more than basic mesh but provide superior protection.
Preparing for Installation
Proper preparation ensures the guards install correctly and perform as intended.
Cleaning the Gutters
Gutters must be completely clean before installing guards. Remove all leaves, twigs, and debris from the channels. Flush the gutters with a hose to clear remaining particles and check that water flows freely to the downspouts.
Inspect for any damage while cleaning. Repair leaks, reseal joints, and fix sagging sections before adding guards. Installing guards over problem gutters just hides the issues without solving them.
Gathering Materials & Tools
Most gutter guard installations require minimal tools. Have the following ready:
Tape measure for measuring guard sections Tin snips or heavy scissors for cutting guards to length Work gloves to protect your hands Safety glasses Ladder with stabilizer
Check the manufacturer’s instructions for your specific guard type. Some systems require additional hardware or tools.
Measuring Guard Quantities
Measure the total linear footage of gutters to be covered. Add 10 percent for waste from cuts. Guards typically come in four-foot or five-foot sections, so divide your total footage by the section length to determine how many pieces you need.
Account for inside corners, outside corners, and downspout locations. Some guard systems include special pieces for these areas while others require field cutting to fit.
Installing Mesh Screen Guards
Mesh screens are among the most common and affordable gutter guard types.
Step 1: Position the First Section
Start at one end of the gutter run. Lay the first screen section on top of the gutter with the back edge tucked under the first row of shingles. The front edge should rest on or just inside the front lip of the gutter.
Some mesh guards have a slight curve. Position this curve so the high point is in the center of the gutter opening.
Step 2: Secure the Screen
Depending on the guard design, secure the back edge by sliding it under the shingles far enough that it stays in place. Some systems include clips that attach to the gutter lip. Others snap onto the front edge of the gutter.
Avoid lifting shingles more than necessary. Forcing shingles up can break the seal and create leak points in the roof.
Step 3: Continue Along the Run
Place the next section with its end overlapping the first section by two to three inches. This overlap prevents debris from entering at the joints. Continue placing and securing sections until you reach the end of the run or a corner.
Step 4: Cut Sections to Fit
At corners, end caps, and downspout locations, you will need to cut guards to fit. Measure the space and mark the guard section. Cut with tin snips, following the marked line. Test fit the piece and trim if needed.
For downspout locations, cut an opening in the guard that allows water to enter the drop outlet. The opening should match the outlet size.
Step 5: Install Around Corners
Inside and outside corners require cutting guards at an angle. Measure the angle of the corner and transfer this angle to the guard section. Cut along the line and fit the piece into place. The corner joint should be tight with minimal gaps.
Installing Solid Cover Guards
Solid covers require more precise installation to work correctly.
Step 1: Check Gutter Pitch
Solid covers rely on proper gutter slope to function. Water must move across the cover surface toward the downspout. If your gutters lack adequate slope, solid covers may not drain properly.
Step 2: Position the Cover
Place the first cover section with the back edge under the shingles. The front curved edge should extend past the front of the gutter. The curve creates the surface tension effect that draws water into the slot.
Step 3: Secure in Place
Most solid cover systems screw or clip to the front edge of the gutter. Follow the manufacturer’s instructions for fastener spacing. Over-tightening can deform the cover and affect performance.
Step 4: Connect Sections
Solid cover sections typically interlock with tongue-and-groove or snap connections. Align the sections carefully so the joint is tight and the surface is continuous.
Step 5: Adjust as Needed
After installing several sections, observe how they align and how the front edge positions over the gutter opening. Make adjustments to ensure consistent positioning along the run.
Installing Foam Insert Guards
Foam inserts offer the simplest installation process.
Step 1: Measure & Cut
Measure the length needed for each gutter section. Cut the foam insert to length with a utility knife or scissors. The foam should fit snugly in the gutter without being compressed too tightly.
Step 2: Insert the Foam
Simply press the foam insert into the gutter channel. Push it down until it sits at the bottom of the gutter. The foam should fill the channel from the back to the front.
Step 3: Fit Around Obstacles
Cut notches or openings for downspout outlets and other obstructions. The foam is easy to shape with a knife.
Step 4: Continue to the End
Work your way along the gutter, inserting foam sections end to end. Butt the sections together without overlapping.
Installing Brush Guards
Brush guards install quickly without tools in most cases.
Step 1: Insert the Brush
Slide the brush guard into the gutter with the bristles facing up. The cylindrical shape should fill the gutter channel.
Step 2: Connect Sections
Brush guards typically connect end to end. Some have loops that link sections together while others simply butt against each other.
Step 3: Cut to Length
If you need shorter sections, cut the brush with wire cutters or heavy scissors. Trim the wire core first, then trim bristles as needed for a clean end.
Maintaining Gutter Guards
No gutter guard eliminates maintenance entirely. All types require periodic attention.
Inspect guards at least twice per year, in spring and fall. Remove any debris that has accumulated on top of guards. Check that guards remain securely attached and have not shifted or sagged.
Even with guards installed, check inside the gutters annually for fine debris that may have passed through. Flush gutters with a hose to clear any accumulation.
Replace foam inserts every three to five years or when they show signs of deterioration. Other guard types last longer but may need repair or replacement if damaged by storms or falling branches.
