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.

The kind of gutter guards you have will affect how often you need to clean them. The more basic type of gutter screen requires cleaning once or twice a year. With a micromesh screen, you may be able to extend the time between cleanings to every two years or so.

However, if you have trees near your roof, you’ll need to clean your gutters more frequently, especially if you have chicken-wire or colander-type gutter guards. If you have pine trees near your roof, you may even need to clean your gutters quarterly, as tiny pine needles can get through any type of gutter guard.

Any small amount of standing water can be damaging to your gutters. It’s recommended that a ¼ inch puddle or more should be addressed. Failure to keep water from pooling in your gutters can result in clogs, algae growth, and pests that damage your gutters over time. 

Usually 1-2 hours, depending on gutter length and condition.
