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.

The most common problem with gutters is clogging from debris like leaves, blossoms, and seeds from surrounding trees. This debris can block downspouts, leading to improper drainage and water overflow.

Other common issues include:

• Leaks and holes, which can often be repaired with gutter sealant or caulk.

• Rust, sagging, or detachment from the roofline.

• Damage from strong storms.

• Improperly pitched gutters that don't drain correctly.

Regular cleaning in the spring and fall is the best way to prevent most of these problems. You may need to clean them more often during periods of heavy leaf fall.

It’s recommended that you clean your gutters after a severe storm, however, regular storms don’t raise the same concerns. Look for signs your gutter might need cleaning after a harsh storm. Do you see broken branches and excessive leaves all over your yard? Chances are your gutters caught quite some debris. Also, ensure a few drying days before cleaning your gutters. Dry debris is much easier to clean.

The cost to clean gutters usually ranges from  $120 to $230, depending on the type, length, and location. Seamless gutters usually come in at the lower end of that range since the lack of seams means there are fewer places for debris to build up. In fact, seamless gutter cleanings usually cost 10% to 25% less than sectional gutter cleanings.
