Failing to clean your gutters can lead to serious and costly damage. When leaves and other debris cause blockages, water cannot drain properly and will overflow. This can lead to water pooling around your home’s foundation, causing basement flooding and structural damage. The overflow can also damage your roof, siding, and fascia boards, with the constant moisture promoting mold, mildew, and rot. The weight of wet debris can cause gutters to sag or break, while stagnant water creates a breeding ground for pests like mosquitoes and rodents. Additionally, runoff can damage landscaping or freeze on driveways and patios, causing cracks. To prevent these issues, it is recommended to clean your gutters at least once or twice a year.

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. 

Icicles don't necessarily mean your gutters are clogged or bad, but they can indicate an underlying issue. While clogged gutters can cause icicles to form, the problem could also be an ice dam on your roof from poor insulation. In that case, melting snow can refreeze in the gutter even without a clog. Regardless of the cause, the weight of the ice can damage your gutters or even rip them completely off the house. If you are unsure of the underlying problem, it's best to call a roofing company to assess the issue and implement a permanent solution.

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.
