Should I Pressure Wash my Roof?

Pressure washing is a fast, effective method to get dust, algae, and other contaminants off your home. Since you’ve already seen the efficiency of pressure washing on your siding and pavement, you might be tempted to try it on your roof. 

However, before you try it on your own, you should consider a few factors.

Is Pressure Washing Good For Your Roof?

It depends on the type of roof you have on your home and whether pressure washing is safe or beneficial. 

Here are the most common types of roofs we see and our take on if you should pressure wash it or not.

Shingle Roofs

Surfaces that can undergo intense water pressure clean up great with a pressure washer. Unfortunately, while asphalt shingles can hold up against rain, they are not built to withstand the powerful stream of a pressure washer. 

Additionally, pressure washers can force water up under the shingles and underlayment, leading to leaks in your home. 

You could only pressure wash your asphalt shingles if you had your machine on a very low setting. This process is called “soft washing” and doesn’t do much more than your garden hose but still helps remove debris and algae from damaging your roof.

Tile Roofs

Tile roofs have plenty of nooks and crannies for mildew and algae to build up. While many companies recommend wiping down the tiles with a towel, pressure washing is a much quicker and more efficient alternative.

Metal Roofs

Metal roofs are the safest and easiest to pressure wash, especially if you have a steep pitch on your home. We can usually reach the roof with the pressure washer from a ladder eliminating the need to climb onto the roof.

Professionally Cleaned Roofs

Pressure washing your roof on your own will be difficult and dangerous if you don’t have the proper training and safety equipment. Rather than risking harm to your home and your health, work with a professional pressure washing company like Wash-In-It. Our team can get your roof cleaned quickly and efficiently, improving the lifetime of your home.
