How to Clean Moss Off Roof - A Step-by-Step Guide

Now let's delve into the step-by-step process of cleaning moss off your roof. Make sure to gather the necessary materials and tools before you begin to ensure a smooth and effective cleaning experience.

Materials and Tools:

You will need the following tools and materials to clean moss off your roof;

• Garden hose
• Commercial moss killer or homemade moss removing solution
• Rubber gloves
• Plastic sheeting
• Large spray bottle
• Soft bristle brush
• Stiff brush
• Chlorine bleach (optional)
• Baking soda (optional)
• Dawn dish soap (optional)
• Galvanized metal strips or zinc strips (optional)
• Pump sprayer (optional)
• Safety rope (for steep roofs)
• Roofing nails (for securing plastic sheeting)

The Procedure

Pressure washing alone can remove the moss, but it leaves the pores. This is why you will need a more detailed solution in addition to your pressure washer.

Step 1: Prepare Yourself and the Place

Put on your rubber gloves and lay down plastic sheeting around the perimeter of your home to protect sensitive plants and prevent moss-infested debris from falling onto the ground.

Step 2: Remove Loose Moss

Using a garden hose with a gentle water spray, wet the roof surface to loosen any remaining moss. Be careful not to apply excessive force as it may damage shingles or lift them. Gently lift any loose moss using a soft bristle brush.

Step 3: Apply Moss Removing Solution

Prepare a moss-removing solution by following the instructions on a commercial moss killer or by making your own solution. Mix water, a small amount of chlorine bleach (if using), baking soda, and a few drops of dish soap in a large spray bottle for a DIY solution. These are solutions that will kill moss on contact.

Step 4: Spray the Solution

Spray the moss-removing solution generously over the moss-covered areas of your roof. Ensure that you cover all the moss-infested regions.

Step 5: Let the Solution Sit 

Allow the solution to sit on the moss for the recommended duration specified on the product label or approximately 15-20 minutes for homemade solutions. This gives the solution enough time to penetrate and kill the moss.

Step 6: Gently Scrub the Moss

Using a stiff brush, gently scrub the moss-covered areas of your roof. Be cautious not to apply excessive force or use harsh chemicals, as they can damage shingles or other roofing materials. You can use a plastic scraper to remove stubborn moss patches if necessary.

Step 7: Rinse Thoroughly

Once you have scrubbed away the moss, thoroughly rinse the roof surface with a garden hose, starting from the top and working your way down. Ensure that water flows away from the roof, promoting proper drainage and preventing standing water.

How Do You Prevent Moss from Attacking Your Roof?

Taking preventive measures is crucial to avoid future moss growth once you've successfully cleaned the moss off your roof. Here are four essential tips to help prevent moss growth and maintain a moss-free roof.

Maintain Proper Roofing Materials and Conditions

4. Keep your roof clean from debris, leaves, and organic matter that can promote moss growth.

Promote Good Drainage and Sunlight Exposure

2. Trim tree branches near the roof to increase sunlight exposure and discourage shady conditions ideal for moss growth.
3. Clear away any fallen leaves or branches that may accumulate on the roof and provide a breeding ground for moss.
4. Regularly remove moss or algae that may start to grow in areas where water tends to accumulate.

Apply Preventive Treatments

1. Use commercial moss killers or homemade solutions as preventive treatments according to product instructions.
2. Consider installing zinc strips along the roof ridge to release moss-inhibiting properties during rainfall.
3. Apply a moss-resistant roof treatment periodically, especially in areas prone to moss growth.
4. Consult a professional roofer to determine the most suitable preventive treatments for your roof type and climate.
