Roof Cleaning questions, answered by experts

It may require stronger cleansers or chemicals, higher-pressure spray, or scrubbing to completely remove algae from a metal roof. Start with a mild cleanser; if that doesn’t work and you're comfortable doing so, use a stronger mix of ⅓ cup of laundry detergent, 1 quart of bleach, and 3 quarts of water to gently scrub the algae with a soft-bristled brush. If algae is present across large portions of your roof, doesn’t come off with gentle scrubbing and cleansers, or is in hard-to-reach areas, this may be a job better left to a pro.

The cost of removing snow from a roof averages between $300 and $700. However, this cost can range from $200 to $3,000, depending on the size of your roof, the amount of snow, and roof accessibility. 

Since snowfall can range from light powder to heavy and condensed snow, part of the price of roof snow removal depends on the amount and type of snow. For 12 inches of snow, you can expect to pay between $200 and $2,000 for this job. However, for 24 inches of snow, that price rises to $300 to $3,000.

The best way to clean a roof without damaging it is to opt for soft washing, or better yet, leave it to a professional roof cleaner. Soft washing involves a biodegradable cleaning solution being sprayed on the roof and gently rinsed away after it dissolves built-up residue on your shingles. 

Other than it looking like a dirty car, there are some other signs you need to clean your roof. Moss growth, algae (often black streaks), grime buildup, buildup under shingles, and leaf buildup are all classic signs a cleaning is overdue. If you have neighbors, take a look around. If your roof appears different in any way, that’s another sign to call a pro to have it cleaned.

Yes, pros use specialized solutions and pressure settings tailored to surface sensitivity.
