Constant assault from natural elements such as the sun, wind, and rain can leave a roof looking old and worn. Mold and mildew can also accumulate, which can destroy a roof’s protective layer. If you want to keep your roof in perfect working condition, regular cleaning and maintenance are key.

Why Do You Need Roof Pressure Washing?
The roof is an important part of any structure, but it is also one of the most vulnerable parts of the exterior. It is constantly exposed to the sun, wind, rain, and snow. Naturally, constant exposure to these natural elements will affect the appearance and quality of a roof. For example, the sun’s UV rays can break down roof shingle aggregates, which is the protective layer that helps extend the lifespan of a roof. Even if your roof has the best quality materials and construction, it will still be susceptible to wear and tear.
In addition, roofs can have an overgrowth of mold, mildew, moss, algae, and other organic material. Not only do they leave unattractive stains on your roof, but they can also cause shingles and other roofing materials to rot.
All these issues can be avoided with proper roof cleaning and maintenance. Professional roof pressure washing should be done at least twice a year — preferably once during the spring and once during the fall. Pressure washing not only restores the appearance of your roof but it also effectively blasts away the harmful substances that damage the roof materials. Pressure washing is also a critical step before reapplying protective sealant on the roof.
Before and during pressure washing, professionals can get a good look at your roof and identify potential problems. Addressing these structural issues early on can save you a lot of time, money, and effort in the future.
What Is Soft Washing?
While it’s possible to pressure wash a roof on your own, roof cleaning is best left to the professionals. This is because roofs are made from more delicate materials such as wood, slate, ceramic, concrete, asphalt, and clay.
Compared to other exterior surfaces, these materials require a more precise and gentler cleaning approach. It’s possible that DIY pressure washing — especially when done by an amateur — may do more harm than good.
Professionals will employ a specific type of cleaning method — called soft washing — to effectively clean your roof. Soft washing a roof is different from the traditional pressure washing process.
Traditional pressure washing is not ideal for roofs as high-pressure water can damage delicate roof materials such as asphalt, clay, and ceramic. Soft washing is a much better alternative because it relies on the use of a biodegradable cleaning solution to remove dirt, dust, debris, mold, mildew, algae, and other unwanted substances from the roof.
Soft washing is much better at addressing the roof of mold, mildew, and algae problems. The cleaning solution not only kills them, but it also leaves inhibitors that prevent these microorganisms from coming back. Thus, your roof will remain clean and attractive for a longer period of time.
How to Soft Wash a Roof
Here’s what you can expect with professional soft washing.
1. Inspect the Roof
Before soft washing, professionals will conduct a thorough inspection of your roof. It’s important to address roof issues beforehand to prevent causing damage and to maximize the effects of roof pressure washing.
2. Pre-wash the Roof
Professionals will use low-pressure water to saturate the roof. Pre-washing the roof can improve the adherence or effectiveness of the soft washing cleaning solution.
3. Apply the Cleaning Solution
The professionals will use a soap dispenser nozzle to apply the cleaning solution to your roof. They will work in small sections at a time for a more systematic approach. The cleaning solution will sit on the surface for at least 15 minutes.
4. Soft Wash the Roof
Professionals will then use a soft washer to rinse the solution from your roof. A soft washer uses low-pressure water so there is no risk of damage to your roof’s surface.
5. Apply Sealant
If necessary, the professionals can apply a sealant to restore the protective layer of your roof. They will only apply the sealant once the roof has completely dried. In some cases, it may take at least 24 hours.
Proper Roof Maintenance and Care
Bi-annual pressure washing isn’t enough to preserve the condition of your roof. You also need proper maintenance and care throughout the year.
Here are some helpful tips that will help keep your roof in tip-top shape:
- Trim overhanging branches near the roof to prevent them from falling on and damaging your shingles.
- Remove leaves, branches, and other debris from your roof regularly.
- Make sure to clear and clean gutters, especially before a storm. If the gutters are backed up, they can contribute to the deterioration or rotting of roof materials.
- Always inspect your roof after extreme weather events like a storm. If there is any damage — even if it is minor — have your roof fixed as soon as possible.
- A well-insulated attic will help maintain the condition of your roof. If the attic is not properly insulated, this can lead to ice dams and excess moisture.
- Look for leaks in the attic, ceilings, and walls. Leaks can signify a serious issue with your roof.
Professional Roof Cleaning Is Worth the Investment
Many property owners avoid roof pressure washing because of the initial cost. However, roof pressure washing has countless benefits, making it a worthwhile investment. Pressure washing not only keeps your roof clean and attractive, but it also prevents issues like mold and algae from causing significant damage. Given the delicateness of roofs, it’s better to have professionals take over the cleaning process. You’ll have peace of mind knowing that experts are soft washing your roof and keeping it in excellent working condition.
