Step 1: Thoroughly Clean the Gutters

Before installing any gutter guard, it’s imperative that you thoroughly clean out the existing gutters. Any accumulated debris, dirt, or leaves must be fully removed to allow for proper installation and functionality of the new gutter guards.

Use a gutter scoop, wet/dry vac, garden hose, or combination of methods to eliminate all loose sediment and organic matter from the gutters and downspouts. This is also a good opportunity to inspect for any damage or leaks that should be repaired prior to installing the new guards.

Take the time to do this properly, as any debris left under the gutter guards will eventually rot and clog, rendering them ineffective. A complete cleaning now will get your gutters into optimal shape for snap-in gutter guard installation.

Step 2: Accurately Measure and Purchase the Correct Size Gutter Guards

Amerimax Snap-In Filter Gutter Guards are available in styles and sizes to fit most residential 5″ and 6″ K-style gutters. Once your gutters are fully cleaned out, you can precisely measure the length and confirm the size of your existing gutters.

Use a tape measure to determine the total linear footage of gutters needing coverage. Remember to account for bends and sections on all sides of the home. Compare this length to the available Amerimax gutter guard styles to determine the exact number of pieces needed. It’s better to have a few extra than to run short mid-project.

When purchasing, verify that you’re getting the proper size guards for your 5″ or 6″ gutters. Getting an incorrect size could lead to poor fitting, leaving open gaps for debris intrusion. Consulting with a knowledgeable retailer will ensure you get the right Amerimax Snap-In Filter Gutter Guards the first time.

Step 3: Snap the Gutter Guards Into Place

With clean gutters and proper materials on hand, you’re ready to move onto gutter guard installation. Amerimax Snap-In Filter Gutter Guards utilize an innovative “snap-in” design for secure fitting without fasteners.

Begin at one end of the gutter run, placing the front edge of the gutter guard up under the shingles. Apply firm, even pressure as you pop the back edge of the guard upwards until it snaps securely under the front lip of the gutter. Work slowly and methodically down the gutter length, snapping subsequent guards into place, being sure each fits snugly against the next.

It may help to have an assistant support the opposite end of the guard as you snap it into place. The snug fit eliminates gaps while allowing the Amerimax guards to slightly flex and adjust to gutter contours. Continue until guards fully cover all gutter sections.

Step 4: Secure the Gutter Guards with Self-Tapping Screws

While Amerimax Snap-In Filter Gutter Guards will stay in place when properly installed, it’s recommended to reinforce them with self-tapping screws for maximum stability. This prevents the guards from popping out if impacted by falling debris.

After snapping each section of gutter guard into place, drive a self-tapping screw directly through the guard and into the front gutter lip. Space screws evenly, approximately every 2 feet along the gutter guards. Take care not to over-tighten the screws, as this could warp or deform the guard material.

Stainless steel screws are ideal for longevity, however standard zinc-plated screws are sufficient. The screws provide rigid support without interfering with the snap-in function of the gutter guard installation.

Step 5: Test Gutter Guard Water Flow Functionality

The final step is to test water flow through the newly installed gutter guards. Use a garden hose to run a heavy stream of water directly into the gutter above each connected downspout. Observe the water as it flows through the gutter guard and empties through the downspouts.

The water should quickly drain without any overflow or backing up, indicating a successful gutter guard installation. Check along the roof edge for any dripping or leakage past the guards as well. If any flow issues are observed, recheck for debris blockages or gaps and reinstall any loose guards as needed.

When functioning properly, Amerimax Snap-In Filter Gutter Guards will keep leaves and debris out while allowing unimpeded drainage of rainwater into the gutter system. Periodic visual inspections are still recommended to ensure no snow or ice buildup in winter months. With proper installation, you can enjoy reduced gutter maintenance for years to come.
