Algae, moss, and debris not only make your roof look unsightly, but they can also shorten its lifespan and increase energy costs. Regular cleaning is essential to protect your roof, and power washing is a popular method homeowners use. But is it always the best choice?
DIY power washing can save you money, but it can also lead to costly repairs.
In this guide, we’ll talk about power washing roofs safely. We’ll also compare power washing to other cleaning methods like soft washing, and share tips to maintain your roof in top condition.
Learn how to protect your home while reaping the benefits of a clean, well-maintained roof.
Power Washing 101
Power washing, a.k.a. pressure washing, uses high-pressure water to remove dirt, grime, moss, and algae from a variety of surfaces. A power washer generates a strong stream of water, ranging from 1,000 to 4,000 PSI (pounds per square inch). The high-pressure stream makes it easy to break up dirt and other stubborn debris.
One thing many people don’t realize is the need to adjust the pressure. It all depends on the surface you’re cleaning.
Softer materials, like wood and vinyl, usually require lower pressure. Tougher surfaces like concrete or stone need higher pressure to effectively clean them.
When used properly, power washing is a quick and effective way to maintain the exterior of your home, especially for large or heavily soiled areas.
Why a Clean Roof Matters
Many homeowners overlook the importance of keeping their roofs clean, but regular maintenance offers several key benefits. From enhancing your home’s appearance to protecting its structure, a clean roof can have a lasting impact.
Here are just a few of the advantages of roof cleaning:
- Extends roof lifespan
- Reduces energy costs
- Improves curb appeal
- Prevents water damage
- Maintains home value
Which of these benefits matters most to you-extending your roof’s lifespan, lowering energy costs, or improving curb appeal? Regular roof cleaning can provide all these advantages, helping to protect your home and keep it looking its best.
Risks of Power Washing Roofs
Power washing is a popular method for cleaning many surfaces, but it can pose significant risks when used on roofs. That doesn’t mean you shouldn’t power wash a roof, but knowing the risks can help prevent future headaches and costly repairs.
Potential risks can include:
- Roofing material damage
- Water intrusion
- Structural damage
- Damage to landscaping
- Voiding the roof warranty
Understanding these risks allows you to make smarter choices and protect your roof from unnecessary harm.
Safe Roof Cleaning Methods
Don’t let the potential risks make you shy away from cleaning your roof. There are effective alternatives to power washing that minimize the risk of damage while achieving great results.
Soft Washing
Soft washing uses low-pressure water combined with specialized cleaning solutions to gently clean your roof. It removes dirt, moss, algae, and mold without damaging your roof materials.
Manual Cleaning
Manual cleaning involves removing debris by hand and gently scrubbing the roof. This method is ideal for smaller jobs, but probably not for the entire roof.
Non-Toxic Cleaning Agents
Another way to protect your roof while cleaning is to use eco-friendly solutions. These agents are safe for the environment and protect the integrity of roof materials.
Safety Tips for Roof Washing
If you decide to take the DIY route, make safety your top priority. Roof washing can be dangerous, especially when using ladders or working at height.
Follow the tips below to protect yourself:
- Use a sturdy ladder
- Wear non-slip shoes
- Wait for the roof to dry before working
- Wear gloves and a harness if needed
- Use scaffolding
Taking these precautions will help keep you safe while you clean your roof. For added peace of mind and to avoid accidents, consider professional roof cleaning services for the more challenging jobs.
Essential Roof Maintenance Tips
Once you’ve cleaned the roof, what’s next? Proper roof maintenance goes beyond just cleaning. Follow these tips–they’re key to a long-lasting roof:
- Clean gutters regularly
- Trim overhanging branches
- Ensure proper attic ventilation
- Check for mold and mildew
While you can perform inspections from the ground, don’t forget to schedule professional roof inspections. Most professional roofing contractors recommend yearly inspections at a minimum. Many advise scheduling inspections twice a year.
Power Washing and Roof Materials
Certain roof types are more vulnerable to pressure washing. Asphalt shingles can lose their protective granules, leading to premature aging. Wood shake roofs may crack or splinter, while slate tiles can break under high pressure.
Older roofs or those with existing damage are also more prone to further harm.
More resilient roof types include clay tiles and metal roofs, though caution is still needed. Clay tiles can tolerate low-pressure washing. Metal roofs are durable but can suffer dents or damage to protective coatings if you’re not careful.
Signs of Roof Damage From Pressure Washing
Not using the correct pressure washing techniques can lead to hidden roof damage. You might not notice the signs immediately, but they usually worsen over time.
- Granule loss
- Missing shingles
- Cracked tiles
- Water stains
- Loose seals
- Damaged wood
- Premature aging
- Sagging areas
Regular roof inspections, especially after pressure washing, should catch most of these before they evolve into major problems.
Is It Time to Call a Professional?
DIY roof cleaning may save money, but most roofs are better cleaned by professionals. Experts know which methods and tools work best for your roof type. Professionals use industrial-grade equipment that outperforms consumer machines.
If your roof shows signs of heavy dirt or algae buildup, or if you haven’t cleaned it in years, call a professional.
