Many roof washing companies advertise pressure washing roofs and pressure cleaning roofs. This sounds like an effective way to get a roof washed but it is not. Pressure washing or pressure cleaning is okay for patios, decks, driveways, walls, walkways- and other hard surfaces such as stone, brick, and cement, not roofs.
Pressure washers produce highly pressurized jets of water that can be used to blast sediment off surfaces. This cleaning method works really well when the surface being washed can stand up to that level of water pressure.
But while asphalt shingles can survive heavy rainfall, rain is not the same as a concentrated beam of water from a pressure washer. Simply put, unless you have the pressure cleaner on a low setting, cleaning your roof with a pressure washer on high will damage your roof while it appears to clean it.
The water pressure won’t damage just the shingles. The high pressure from the pressure washer could work through the adhesive bond holding your shingles together, and seep into and damage your roof’s fabric underlayment. Plus, pressure washers tend to blast sediment into the air, so it’s likely any dirt you do scrape off your shingles is bound to fall back down onto another section of your roof.

When there are other features on a roof, such as vents, skylights, flashing, chimneys, solar panels, and any other items, high-pressure water could compromise the sealants on any one of those elements, plus create leaks. The water temperature could be a problem as well. Water that is too hot could damage any roofing parts, and if the angle of the spray coming towards the roof is incorrect, along with any spray repelled away from the roof, the high pressure from the spray could cause serious roof damage.
