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. 

Whether or not you can use a pressure washer to clean your gutter guards depends on the type of gutter guard you have and the strength of the pressure washer. Most gutter guards can handle a low-pressure setting but check first. If you’re unsure if your gutter guard is designed for pressure washing, check your manufacturer’s instructions, ask a pro, or use a garden hose to clean the gutter guard instead. As gutter guards age, they become less resistant to the strong forces of a power washer, so treat older gutter guards with more care.

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.

While both underground and above-ground downspout extensions are a step up from no downspout extensions, underground downspouts are better for those looking for a more discreet option. Underground downspouts are hidden away—out of sight, out of mind. You won't be bumping into the extended sections with your lawn mower, nor will you see the downspouts sticking out like a sore thumb.
