Your roof is more than just a protective barrier— it's one of the biggest investments in your home. So, why leave its care to just anyone? Choosing the right roof cleaner doesn't have to be overwhelming. By asking the following four critical questions, you'll gain clarity on who to trust with this important task.

1. How do you clean the roof?
The method a roof cleaner uses matters—a lot. The only cleaning method approved by the Asphalt Roofing Manufacturers Association (ARMA) is a chemical mixture of water and sodium hypochlorite, applied with no pressure. If a cleaner mentions "pressure" or "chemical and pressure," it’s time to walk away. These methods often involve sodium hydroxide, which can damage asphalt shingles by breaking down the petroleum base. What's worse, the high-pressure rinsing required to remove sodium hydroxide can strip the top granules off shingles, leading to premature roof failure. Protect your roof by ensuring the cleaner follows ARMA guidelines.

2. Are you insured?
This question is non-negotiable. Hiring an uninsured company could leave you responsible for costly damage if something goes wrong. Imagine finding out the hard way after your roof has been compromised! Reputable roof cleaners will gladly provide proof of general liability insurance. For example, our company ensures coverage of up to one million dollars. Don’t hesitate to ask—your peace of mind is worth it.

3. Will my plants and bushes be safe?
Sodium hypochlorite, the active ingredient in roof cleaning solutions, is biodegradable when properly diluted. However, its concentration needs to be higher when used for roofs. A responsible roof cleaner will have protocols in place to prevent harm to your plants and landscaping, either by collecting runoff or thoroughly diluting it. If the cleaner can’t clearly explain their process for protecting your vegetation, proceed with caution—replacing damaged greenery can be both expensive and frustrating.

4. Am I getting quality work at an affordable price?
The phrase "you get what you pay for" couldn’t be truer when it comes to roof cleaning. Be wary of offers like "$150 roof cleaning"—these too-good-to-be-true prices often indicate corner-cutting methods that may jeopardize your roof’s integrity. Considering that the average roof replacement can cost around $8,000, it’s better to invest in a trusted, experienced cleaner who delivers quality work at a fair price.

Final Thoughts
Choosing a roof cleaner doesn’t have to be stressful when you know what to ask. Protect your investment by finding a professional who prioritizes safety, quality, and transparency. And remember, while price matters, the long-term value of expert care far outweighs the risks of taking shortcuts.
By following these guidelines, you can ensure your roof stays in excellent condition for years to come.
