Pressure washing is the use of high-powered water to clean a surface. The pressure washer uses water at high pressure and shoots it out in a jet or flow of water to remove dirt or contaminants from surfaces. The pressure of the water used for pressure washing is measured in pounds per square inch (PSI) and should not exceed 1,800 PSI. The high-powered water can cause damage to surfaces such as stucco, brick, or masonry siding. If you power wash a part of your house that has been repainted, the water pressure can pull away some of the paint and cause damage. The pressure from your water jet is so powerful it can easily tear through the adhesives that hold shingles together. The force of a high-pressure hose could also rupture your roof's fabric underlayment AND blast dirt into the air, which rains back down onto other parts of your roof!
NEVER PRESSURE WASH YOUR ROOF
There are several ways in which you can clean your roof, but one that you should never do is use a power washer. It's not a good idea to use high-powered water as it can cause damage and force the shingles off, especially if you have asphalt shingles.
It's always best to hire professionals if you need to clean your roof, as they have the equipment and tools to do the job right without putting damage or force on the roof. You don't want to damage your home by pressure washing your roof, so consider hiring a professional if you have doubts about what you can do or need help getting it done.
ALTERNATIVES TO PRESSURE WASHING YOUR ROOF
If you have leaves, moss, or other organic matter on your roof, consider using a rake or a leaf blower to remove them. It is best to remove any organic matter before it has a chance to decay and damage your roof's shingles. You can use an old push broom or get a proper roof rake designed to clean your roof. They usually have firm nylon bristles and are comfortable in your hand. Make sure you buy the correct type of rake, one designed for cleaning roofs.
MOLDY ROOF STAINS
If you have moldy roof stains, just use your garden hose spray nozzle and some nontoxic chemicals to remove those ugly black streaks. The result? Your shingles will look as good as they did the day they were installed.

Your best bet is either replacing them or having professional roofers repair them for you because they are much better equipped to handle such a job.
