Walking on the roof to clean gutters is unsafe and not recommended due to significant safety risks. It is especially dangerous on steep or slippery roofs, or if the roof is wet or covered in leaves, which increases the chance of a fall. In addition to personal injury, walking on the roof can damage shingles, potentially leading to water leaks. Instead of walking on the roof, use a sturdy ladder positioned on a stable surface to access the gutters. Be aware that using a ladder also carries risks, as it can be difficult to maintain balance while performing the work. You can also use ground-based cleaning tools. For safety reasons and to prevent damage to your roof, hiring a professional to clean your gutters is the best and safest option.

Underground downspouts refer to the sections of downspout extensions that lead away from your home and gutter system. While they cost more than traditional extensions, they can provide several benefits, such as less frequent damage and no need to move them for lawn care tasks. Whether they're worth it or not depends on your budget at installation time and how much convenience they'll add to your situation.

Absolutely—and lots of it. Overflowing water from your gutters can damage your siding and your roof. All of the moisture getting into the cracks and crevices of your home can lead to mold or mildew problems down the line. In addition, when water pools around your home, it needs a place to go—and sometimes it ends up inside the house, creating a very unwanted flood.

Yes, you can use a pressure washer to effectively clean debris, dirt, and grime from your gutters, but it must be done with caution to avoid damage. Always use a low-pressure setting, with a recommended range between 1,200 and 1,800 PSI. Excessive pressure can bend or dent aluminum gutters, damage seams, peel paint, or even knock shingles off your roof, potentially leading to leaks and moisture issues. For a safer alternative, consider soft washing or cleaning them by hand. When using a pressure washer, it is safer to use gutter elbow extensions from the ground rather than climbing a ladder, as the force can cause instability. Due to the risks, you may want to hire a licensed and insured contractor for the job.
