Gutter Cleaning FAQs, answered by experts

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.

Shingle granules can be cleaned out of gutters using a small scoop or a hose, depending on the quantity of granules and how much other debris is in your gutters. First, clear your gutters of leaves and other debris. This may remove granules in the gutters if they are mixed in with the debris. Use a plastic scoop to remove larger quantities of granules or a hose with a high-powered nozzle for smaller amounts, and collect and dispose of the granules once they’ve been removed.

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.

Ensures thorough cleaning, preventing blockages and potential water damage.

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.
