How much does a roof cleaning cost?

Depending on the size of your roof, height, and your region, roof cleaning can cost around $400 for a roof cleaning. This can be an investment if you are selling your home, since it can increase the appraisal value of your home by up to several thousand dollars.

Some roofing cleaners will charge per square foot at about $0.20 to $0.30 per square foot. Most cleaners have a minimum charge, so if you only need about 10 square feet cleaned, be prepared to pay more than the small amount.

For a do-it-yourself roof cleaning, it can be cheaper to simply rent a power washer or backpack sprayer to clean your own roof, though it can be significantly more dangerous if you go on top of a wet roof while cleaning. A power washer can rent for anywhere from $55 to upwards of $120. The cleaner itself is a small amount at about $5 to $8 to purchase enough bleach to clean your roof. A backpack sprayer is less expensive to rent, but is more dangerous since it requires you to walk on the roof more to clean effectively.

Dor even more effective cleaning, invest in a pre-wash solution to clean moss and algae from most roofs. This will make it even more slippery, so clean with care or hire a professional.
