Yes, gutters can still get clogged even with gutter guards installed. While guards significantly reduce the amount of debris that enters your gutters, they are not 100% effective.

Small debris such as pine needles, seedlings, algae, small leaves, and pebbles can pass through the guard's screen or mesh and accumulate over time. Clogs can also form if the guards themselves are not cleaned and become overwhelmed with debris on top, preventing water from entering the gutter.

If this buildup is neglected, it can lead to clogs, water leaks, mold growth, and even plants sprouting from the gutters. The primary benefit of gutter guards is not the complete elimination of maintenance, but a dramatic reduction in how often you need to perform it, often from several times a year to just once a year or less.

To clean the tops of gutter guards, use a soft-bristle brush or a leaf blower to remove debris like leaves, twigs, or dirt. For stubborn grime, spray the guards with a garden hose, directing water downward to avoid forcing debris into the gutter. If the guards are removable, take them off and rinse thoroughly before reattaching. Regular cleaning, especially during fall or after storms, will help maintain their effectiveness.

Buried downspouts can freeze during cold weather as cold water runs through them. If you’ve discovered your downspouts are frozen, you can carefully pour hot water down the top of the downspout to defrost them. If that doesn’t work, you may need to dig your downspout back up. Avoid trying to break the ice from the exterior using a hammer as this can cause cracks and damage to your downspout.

To avoid freezing the future, consider adding a heating cable to the exterior, which can adjust heat based on the surrounding temperature.

The cost to install a downspout extension or reroute a downspout generally falls between $30 and $200. The final price depends on factors like whether you DIY the project or hire a gutter professional, the complexity of your gutter system, and the length of the new extension. A simple, above-ground DIY installation can cost as little as $30 for materials. In contrast, a more complex project involving professional installation and digging trenches for underground piping could cost over $1,000. This is still a significant saving compared to replacing your entire gutter system, which costs around $1,900 on average.
