Whether or not you can use a pressure washer to clean your gutter guards depends on the type of gutter guard you have and the strength of the pressure washer. Most gutter guards can handle a low-pressure setting but check first. If you’re unsure if your gutter guard is designed for pressure washing, check your manufacturer’s instructions, ask a pro, or use a garden hose to clean the gutter guard instead. As gutter guards age, they become less resistant to the strong forces of a power washer, so treat older gutter guards with more care.

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.

It’s best to schedule regular gutter cleanings before there’s a major issue, but sometimes life gets in the way. Luckily, a few telltale signs will let you know when to clean your gutters ASAP:

• You notice built-up debris in your gutters.

• Your gutters overflow with water when it rains.

• Water doesn’t readily flow from your downspouts.

• Your gutters are damaged or visibly leaking.

• You notice evidence of leaking along your roof, siding, yard, or pavement.

• Your gutters have pulled away from your roofing or exterior walls.

• You see water damage on your soffits or fascia.

• You have weeds growing in your gutters.

• You start to see ants or other insects around your gutters or in your home.

• You suddenly have issues with leaks in your crawl space or basement.

On a typical three-bedroom home, gutter cleaning takes about one hour. For larger homes, especially those with multiple stories, the job can take two to three hours. The time required may increase if the gutters need extensive cleaning, the roof is steep, the gutters are hard to reach, or if gutter guards need to be uninstalled and reinstalled.
