Transform Your Home’s Curb Appeal: The Ultimate Guide to Safe Power Washing Roof Cleaning
Your roof faces constant assault from nature’s elements, accumulating moss, lichen, and debris that can cause serious damage if left untreated. Roof moss and lichen will not only damage roofs by eating away at the calcium carbonate in the limestone, but can also lift up edges of shingles, making them vulnerable to wind damage. Furthermore, moss can hold up to 20-30X it’s weight in water, causing pre-mature aging of the roof and a high potential for water intrusions. Understanding proper safety protocols and effective cleaning techniques is essential for maintaining your roof’s integrity while achieving outstanding results.
Why Professional Roof Cleaning Matters
Unlike algae, moss can be detrimental to asphalt shingle performance. Moss can cause the leading edges of the shingles to lift or curl, which increases the risk of shingle blow-off during wind events. In severe cases, moss build-up can cause lateral water movement resulting in moisture damage to the roof deck or may even cause leaks. This makes professional roof cleaning not just a cosmetic improvement, but a crucial home maintenance task.
For homeowners in Maryland’s Frederick County, where Maryland’s humid summers and seasonal weather affect your exterior surfaces, regular roof maintenance becomes even more critical. In North America, moss tends to grow on north facing roof planes that receive less direct sunlight and stay damp longer than south facing planes. Overhanging tree branches provide additional shade and drop debris on the roof that further holds in moisture and acts as a food source for moss.
The Dangers of Improper Roof Cleaning
Many homeowners make critical mistakes when attempting DIY roof cleaning. Never use a pressure washer or a pressurized stream of water on your roof. Pressure washers can be very strong and certainly strong enough to break a shingle’s adhesive and lift it up. They also can strip asphalt shingles of their granule surface, which can ruin their performance and destroy their color. Any amount of pressure washing can cause serious problems with the roof, including major leaks.
NFRC would never recommend the use of pressure washers to clean moss, lichen or algae off a roof as the high pressures can damage the tiles or reduce their overall service life. Pressure-washing roof tiles can remove this protective layer. This is why professional expertise is invaluable when dealing with delicate roofing materials.
Safe and Effective Cleaning Techniques
The Soft Wash Method
The safest way that Trotta’s Power Washing has found, and that has been proven in many other power wash companies throughout the country that we’ve done research with, is a no-pressure approach. That’s why Trotta’s Power Washing ditches the pressure and uses a chemical cleaning solution that keeps your roof and shingles safe.
Professional power washing frederick companies like High Pro Power Washing Service Inc utilize specialized soft washing techniques.

When you call, you’re talking to people who live and work in Frederick, not a call center three states away.
Chemical Treatment Protocols
The most effective method of cleaning algae and moss from a roof is with a 50:50 mix of laundry strength liquid chlorine bleach and water. Apply with a sprayer and allow the solution to dwell on the roof surface for 15 to 20 minutes, and then rinse thoroughly with low pressure water. Extended dwell times may be necessary, however, avoid letting the solution dry completely as this may prevent complete rinsing.
Trotta’s Power Washing uses a powerful chlorine bleach solution for roof cleaning that will kill moss on contact. If our chemical solution doesn’t eliminate every spore from your roof shingles, we’ll reapply it until they are perfectly clean. Additionally, rather than pressure washing the solution off and risk damaging your roof, we let it eat through the remaining moss and wear off naturally.
Essential Safety Protocols
Personal Protection Equipment
Avoid contact with eyes and prolonged skin contact. Wear safety goggles and gloves when cleaning to uphold the highest safety standards. Keep out of reach of children and pets. Do not ingest. If swallowed, drink water and seek immediate medical attention.
Working at Height Safety
Accessing the roof can pose dangers to householders who do not possess the training to work safely at height. The preferred method would be the use of a system from ground floor to eliminate any working at height. Professional companies have specialized equipment that allows safe cleaning from ground level or with proper safety measures.
The safest way to do this is to use a Transfer Pump to spray your roof. If your roof area is walk-able then a garden-style pump sprayer may be all that is needed – however, a steep roof must be sprayed from the ladder. The safest way to do this is to lean a ladder up on your roof above the gutter line. Be sure to use a ladder stabilizer to prevent the ladder from sliding along the gutter!
Environmental Considerations
Take proper precautions to protect landscaping and surrounding areas from the chlorine bleach solution. Use appropriate personal protective equipment when working with chlorine bleach. High Pro Power Washing prioritizes environmental safety, using environmentally friendly and biodegradable cleaning solutions that are safe for your home, garden, and surrounding landscape. Our products are carefully selected to remove dirt, mold, and grime effectively without causing harm to plants, pets, or property surfaces.
Professional vs. DIY: Making the Right Choice
The reality of it all is that if you are careful and gentle, you can effectively make a moss covered roof look great the same day of service while not causing additional damage to the roof. However, this requires extensive knowledge and proper equipment.
Since roof cleaning is not recommended to be a DIY project due to the inherent risk of injury/death, hire a professional to assess your situation! Bluntly put – anytime you get on your roof you run the risk of self-injury, ladder accidents, and lastly, hard work. Cleaning your roof is no easy task and aside from the personal safety risk, it is something that can actually lead to more issues if not done correctly.
When to Schedule Professional Roof Cleaning
Spring and fall are ideal for power washing in Maryland. Spring cleaning removes winter buildup and prepares surfaces for the active outdoor season. Fall cleaning eliminates summer mold and mildew growth before winter weather sets in. We can work year-round when temperatures are above freezing, but avoid scheduling during peak summer heat or when freezing temperatures are expected within 24 hours of service.
Most Frederick homes benefit from power washing every 1-2 years, depending on exposure and environmental factors. Homes with lots of tree coverage or facing prevailing winds may need annual cleaning, while others can go longer. Your siding material also affects frequency – vinyl and aluminum show dirt more quickly than brick or stone. Signs it’s time include visible mold or mildew, dark streaks on siding, or green buildup on walkways and driveways.
