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.

Clean regularly, inspect for rust or damage, and apply sealant to joints as needed.

Gutters should be cleaned at least twice a year, in the spring and in the fall, to remove the debris from trees that can clog the eavestroughs and downspouts. Debris like leaves, twigs, and seed pods can build up and cause your gutters to overflow, potentially causing damage to your roof and foundation. Water backing up under the shingles can rot the edge of your roofline. Overflow water falling next to your foundation can end up leaking into your basement or crawl space.

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.
