Get matched with top gutter cleaning pros in your area

On average, gutters last between 15 and 25 years. Certain materials (stainless and galvanized steel, copper, and cast iron) will have much longer lifespans, with much higher price tags. Vinyl typically lasts only 10 to 15 years, while the second most commonly used material, aluminum, lasts an average of 25 years. Only you as the homeowner will know if the additional cost of upgraded materials makes sense for your home.

When cleaning gutters, your pressure washer shouldn’t exceed a pressure rating range of 1,500 and 1,800 psi. Remember—gutters are designed to withstand the pressure of heavy rain and not much else. While the force of the water in a pressure washer will get rid of the dirt and debris, too much force can damage your gutters and, if you’re not careful, your house. A high PSI will have you prepped to call a professional when your gutter leaks. It could also mess up the gutter joints or even blow the tiles off of your roof.

The gutter gauge is a measurement of the thickness of the gutter material. If you have gutters that are too thick and heavy for the screws and brackets holding them in place, they may sag. Materials that are too thin could suffer damage that leads to sagging. A professional gutter installer can ensure you have the right gutter gauge.

Gutter life expectancy depends on the material used. Aluminum gutters last up to 25 years, while galvanized steel lasts between 15 to 20 years. Copper gutters are the most durable, with a lifespan nearing 100 years. Regular maintenance, such as cleaning and inspecting for leaks, can extend lifespans.
