You are in the middle of using a pressure washer to clear grime, algae, and dirt from your driveway and walkways, only to gaze up and see that your home’s roof is in an equally dirty condition. It isn’t much of a leap to wonder if you could use your pressure washer on the roof. It probably wouldn’t surprise you that roofing companies often get asked, “Can you pressure wash a roof?” Reaching a consensus on this question is challenging. There are as many articles online telling you how to do it as there are ones that say never to do it.

Can You Pressure Wash a Roof?

To formulate an accurate response to the question of, “Can you pressure wash a roof?” one must clearly define what is meant by pressure washing. If you mean a high-powered pressure washer, the answer is a resounding no. There is far too much risk of damaging the shingles and displacing the necessary granules. Even a pressure washer rated for home use can be too strong, especially if the nozzle is too close to the shingles during the cleaning process.

With the right precautions in place, the right equipment, the proper cleaning solution, and expertise, it is possible to clean a roof. If that sounds like a lot of prerequisites, that’s because it isn’t as easy as it might seem, and certainly nothing like cleaning your driveway or walkways. Instead of asking, “Can you pressure wash a roof?” the better question is, “Should you pressure wash a roof?” The answer is most likely that you should not.
