The high-pressure water stream is able to penetrate deep into cracks and crevices on the roof, removing the lichen without causing any damage. The average cost of pressure washing a roof to remove lichen is around $400-$600, with the price varying based on the size of the roof and the complexity of the job.

Hand Scrubbing/Scraping

For those who prefer not to use pressure washers, hand scrubbing and scraping is another option.

This method requires more time and effort, but it can be less expensive than pressure washing. The cost of hand scrubbing and scraping a roof to remove lichen is typically around $200-$400, depending on the size and complexity of the job.

Pressure washing and hand scrubbing are two of the most common methods for moss removal.

Pressure Washing

Pressure washing is a popular choice for removing moss from a roof. It involves using high-powered water jets to blast away the moss. This method is typically faster than hand scrubbing, but it also comes with risks. Pressure washing can damage some roofing materials and can be dangerous if not done properly.

The average cost of pressure washing a roof to remove moss is between $0.35 and $0.75 per square foot, depending on the size and complexity of the job.

Hand Scrubbing

Hand scrubbing is a slower process than pressure washing, but it is generally safer for most roofing materials. It involves using a brush or broom to scrub away the moss. The average cost of hand scrubbing a roof to remove moss is between $0.50 and $1.00 per square foot, depending on the size and complexity of the job.

Removing Algae from Your Roof

Algae can be a common problem on roofs and can cause discoloration and staining, as well as leaving a slippery surface. Removing algae from your roof can help to restore its aesthetic appeal, as well as preventing any further damage that it may cause.

There are two main methods for removing algae from a roof: chemical treatments and pressure washing/hand scrubbing.

Chemical Treatments

Chemical treatments are one of the most effective ways to get rid of algae from your roof. These treatments use chemical compounds to kill the algae and prevent it from coming back. The cost of chemical treatments will vary depending on the size of the roof, but typically range from around $200 to $500.

Pressure Washing/Hand Scrubbing

Pressure washing or hand scrubbing are also effective methods for removing algae from your roof. Pressure washing is usually the more cost-effective option, costing around $150 to $300, while hand scrubbing can cost anywhere from $200 to $500, depending on the size of the roof.

Moss, algae, and lichen can be unattractive and damaging to a roof if they are not removed.

Homeowners should also consider treating their roofs with chemicals to prevent future growths, as this may be a more cost-effective option in the long-term. It is important to remember that removing moss, algae, and lichen from your roof can be a difficult and dangerous job, so it is recommended that you hire a professional to do the work for you.
