Maintaining the flow and cleanliness of your rain gutters is one of the most important home improvements you can make for your roof. Rain gutters that are clogged with debris can trap water on the roof, causing the roof to deteriorate over time. They can also prevent the snow from melting and falling off the house properly.
When rain gutters aren't cleaned out, they can retain water and provide ideal breeding grounds for all types of creatures, and the worst part is that you can't get to them easily and don't realise you've created a creature paradise.
Cleaning out rain gutters with a pressure washer may sound like a messy chore, but if done correctly, it's not at all filthy, and blasting all the debris away is actually rather enjoyable. For homeowners who want to clean their rain gutters this manner, the first thing I recommend is getting a long wand and setting their pressure washer to 1100 PSI. It's then logical to install a 15-degree spray tip. The next step is to find a solid ladder that faces the spray direction, lean against it, and hold the spray gun with both hands.
Then, instead of spraying directly into the rain gutter, spray just above it, which will cause all of the loose leaves and debris to fly away, allowing you to see what you're doing. Next, slightly lower the wand to allow water to flow out and begin chipping away at the remaining debris. Eventually, you'll be able to place your wand into the rain gutter itself and remove all of the debris. It's critical to have a steady stream of water flowing down the gutter while you're working, so keep that in mind.
