Professional roof cleaning in Virginia typically runs $250-$600, depending on your roof’s size, pitch, and condition. Factors affecting price include square footage, height, accessibility, and the extent of algae or moss growth. Complex roofs with steep pitches, multiple stories, or heavy moss buildup require more time and specialized techniques. But even at the higher end, this investment is minimal compared to premature roof replacement costs of $15,000-$30,000. The smart approach is getting a personalized assessment. We provide clear, upfront pricing with no hidden fees, so you understand exactly what you’re investing in and why it’s worth it.
