Gutter Cleaning FAQs, answered by experts

Gutters overflow in heavy rain for several reasons. The main reasons why your gutters could be overflowing in heavy rain include:

  • Not enough downspouts to effectively remove water from your gutters

  • Too small of a gutter width—the average gutter size is four to six inches

  • Clogged gutters

  • Incorrect slope

If you believe your gutters were installed incorrectly, it’s a good idea to know who to call for gutter leaks. Speak with a local gutter specialist to get to the bottom of your gutter system to stop water from flooding your property or yard ASAP.

If you want to avoid burying your downspouts, several alternatives can help direct water away from your home's foundation. One option is to connect a rain barrel to your downspout. During a storm, the barrel collects water that you can later use for irrigating your lawn or garden. Another common solution is to install an above-ground downspout extension. This can be done in a couple of ways:

  • Splash Guards: Placing a splash guard, available at most hardware stores, under your downspout can act as a simple funnel to direct water away from the house.

  • Downspout Extensions: You can add an extension to the end of the downspout's elbow to carry water further into your yard. Some extensions are flexible, allowing you to maneuver them around landscaping.

These above-ground solutions are particularly useful if your home has a slab foundation that you cannot dig up. However, they have limitations. An extension may not move water as far from your home as an underground system. More importantly, if your yard slopes back toward your house, these methods will be ineffective, and burying your downspouts remains the best option to prevent potential flooding and water damage.

While both underground and above-ground downspout extensions are a step up from no downspout extensions, underground downspouts are better for those looking for a more discreet option. Underground downspouts are hidden away—out of sight, out of mind. You won't be bumping into the extended sections with your lawn mower, nor will you see the downspouts sticking out like a sore thumb.

You can clean the gutters on a two-story house using gutter tongs on an extension pole. However, cleaning second-story gutters from a ladder or the roof is very dangerous and should be done by a professional.

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.
