FAQ: How Do I Clean a Wood Shake Roof?
Cleaning a wood shake or cedar roof helps extend its life and keeps it looking its best. But if done the wrong way, you can do more harm than good.
How should I clean a wood shake roof?
Use a soft-bristle brush or low-pressure wash.
Apply a non-toxic roof cleaner made for wood, like those formulated for cedar shakes.
Let the cleaner sit as directed, then rinse gently with a garden hose or low-pressure sprayer.
What should I avoid?
Never use a high-pressure power washer—it can damage the wood fibers and shorten your roof’s life.
Skip bleach or harsh chemicals—they dry out the shakes and lead to cracking.
Don’t walk heavily on the roof. Wood shakes can split or shift under too much pressure.
What does a safe cedar roof cleaner do?
Removes moss, algae, mildew, and stains without damaging the wood
Maintains the natural oils in cedar, which are key for durability
Restores the natural color and appearance
How often should I clean it?
Every 3 to 5 years, depending on tree coverage and moisture.
Clean sooner if you see moss, mildew, or dark streaks.
Consider routine roof inspections to catch issues early.
What cities in Georgia need this most?
Homes in Atlanta, Athens, Roswell, Sandy Springs, and Johns Creek often deal with high humidity and shade—perfect conditions for moss and mildew. If you live in a wooded neighborhood or near water, your cedar roof is more likely to need regular care.
FAQs Homeowners Ask
Can I pressure wash a cedar shake roof?
No. High pressure will strip the surface, split the shakes, and void warranties. Always soft-clean instead.
What’s the best product to clean a wood roof?
Look for non-toxic, biodegradable cleaners made specifically for cedar or wood roofing. These are safe for plants, pets, and your roof.
Do I need a professional to clean my wood roof?
It’s a good idea. Roof cleaning involves height, safety gear, and knowing how to treat wood without damaging it. A professional roofer will also spot early signs of wear or leaks.
