Your roof works hard to protect your home — and moss can quietly cause damage over time. That’s why we focus on safe, thorough moss removal and long-lasting prevention.
We remove at least 96% of moss using roof-safe brushing methods, then apply zinc sulfate treatment to prevent it from coming back. This protects your shingles, preserves the glue that seals them, prevents granular loss, and keeps moisture and weight from damaging the plywood underneath.
Our approach is:
- Safe for your roof – no pressure washing or harsh scrubbing
- Controlled & precise – zero overspray or chemical drift
- Long-lasting – prevents moss regrowth for years
- Plant-conscious – safe for most landscaping with precautions for sensitive plants
Below, we answer the most common questions homeowners have about moss removal, zinc treatment, and roof care — so you can feel confident your home is protected and well-maintained.
Application & Safety FAQs
Q: Is moss removal safe for my roof shingles?
A: Yes — when done properly with the right method. Our approach is designed to protect your shingles while removing moss effectively.
Here’s how we do it:
- Wetting the shingles – We lightly dampen the roof to loosen moss, reducing the need for aggressive scrubbing.
- Gentle brushing – We carefully brush the moss away, taking care not to expose or damage the fiberglass layer in your shingles.
- Specialized tools – We use 6×19 wire brush heads attached to 12-foot Unger telescopic poles, allowing us to reach and clean the roof safely from the ground or a stable position.
Our case studies show that this method, combined with zinc sulfate moss prevention, achieves 96% or greater moss removal. Removing less moss allows regrowth to happen faster, even when prevention is applied. By thoroughly removing moss and applying zinc sulfate properly, we can prevent moss from returning for long periods of time, protecting your roof and the things that matter most.
Why thorough removal matters:
- Protects the shingle bond – Moss growth can lift the adhesive that seals shingles, allowing water to blow underneath.
- Prevents moss in the middle of shingles – This “nasty” growth can eventually punch holes through the shingle.
- Reduces granular loss – Moss accelerates the loss of protective granules.
- Protects roof structure – Moss traps moisture and adds weight, which over time can damage the plywood beneath your shingles.
By removing moss carefully and preventing its return, we preserve your shingles, maintain roof integrity, and extend the life of your roof.
Q: Do you use pressure washing to remove moss?
A: No. Pressure washing can strip shingles, damage roofing material, and shorten their lifespan. Our brushing method is gentler and just as effective, giving your roof a clean, long-lasting result without risk.
Q: How do you ensure no overspray or chemical drift?
A: Our moss prevention treatments are applied with precision to avoid overspray. We use controlled, roof-safe application techniques that protect your landscaping, gutters, and surrounding property. Unlike high-pressure sprays, our methods keep chemicals where they belong — on your roof.
Q: How long does moss removal take?
A: Most homes can be completed in a few hours. Larger roofs or roofs with heavy moss may take longer, but our team works efficiently without cutting corners, delivering professional results that last.
Q: Can I schedule treatment in winter or rainy seasons?
A: Yes. Moss removal can be done year-round. Winter is actually ideal because freezing and thawing help loosen moss, making it easier to remove. We always monitor weather conditions to ensure safe and effective application.
Q: Do you guarantee your moss prevention work?
A: Absolutely. We back our work with a warranty on moss prevention. Our precise removal and careful application methods, combined with zinc sulfate treatment, ensure your roof stays clean, protected, and structurally sound for the long term.
