Using a Power Washer As a Roof Cleaner

Cleaning a roof can be tricky because a powerful power washer could damage shingles. Using the right nozzle on the power washer, though, can help to remove moss and mold growth from a roof without damaging it. Moreover, it’s safer than climbing up on the roof and doing it manually. Plus, it’s a much quicker process.

It is a powerful tool that can scrub away mold and grime from walls, strip paint off of fences, and clean off gunk from outdoor furniture. However, it can also be very dangerous when used incorrectly. A power washer can spray water at high pressure, causing serious damage if it gets into your home’s electrical panel or any outdoor wires. If this happens, you can get an electric shock or even cause a fire.

To avoid this, you should only use a pressure washer when it’s appropriate, such as when cleaning your roof. You can purchase a special soap dispenser nozzle that works with low pressure, or you can use a soft wash power washer that rinses the dirt off the surface of your roof without damaging it. Soft washing typically uses chemicals and cleansers that dissolve dirt so it can be rinsed away with a low-pressure hose. This method prevents moss, mildew, and fungus from holding extra moisture against your shingles and roof paper, which can lead to leaking and deterioration.


A power washer is much more efficient than traditional cleaning methods like scrubbing by hand. It will save time and money, as well as provide better results.

It will help to protect the environment, as it uses less water than traditional cleaning techniques. Additionally, it will reduce the risk of damage to the roof surface and surrounding plants.

Power washing the roof can also increase its lifespan, as it will remove contaminants that can lead to deterioration. It will also improve curb appeal, as a clean roof will look much more attractive than one that is covered in debris, mold, and algae.

When using a power washer to clean your roof, be sure to use the right setting. Using too much pressure can cause damage to your roof and may even require roof repairs. Also, be sure to keep the nozzle clean and to check the hose regularly for leaks. This will ensure that the roof is cleaned properly and efficiently.


When your roof is dirty, it makes the entire house look unkempt. Cleaning it with a power washer can remove mildew, mold, algae and dirt and make the house look better. It will also extend the life of your roof and increase its curb appeal. Before you start cleaning, though, you need to prepare the area. You will need the power washer, detergent, gloves and eye protection. You should also clear the area around your home of any debris that could clog up the hose or block the runoff. You should also wet down the roof before you start cleaning to help loosen up any dirt that has built up. Once you’re finished, rinse off the detergent and remove any debris that has been loosened.

Power washers can be harsh on shingle roofs, so it’s important to only use a moderate pressure for cleaning. Too much water pressure can cause damage that requires costly roof repairs.

A professional power washing company will use a special detergent or surfactant for the best results in cleaning roofs. This type of cleaner is designed to dissolve thick grit, grime and dirt without drying out roofing materials. These cleaning solutions will also kill mold, mildew, moss and algae while leaving a growth-inhibiting residue on the surface of shingles and tiles.

Once the cleaning solution has been left on the roof for the recommended time, a professional will rinse it using a low-pressure power washer. They will take care to protect landscaping and foundation plantings with tarps as needed. This powerful surface cleaner can even clean moss and mildew off of a deck, cement or brick surfaces. It works fast and gets the job done.
