Moss On Your Roof? A Complete Guide To Moss Removal

Your roof is the most important part of your home’s exterior, and it’s responsible for protecting you and your family from harsh weather, amongst other things. But your roof also faces regular wear and tear during this time, which deters its functionality as well as appearance. 

One common roofing problem that you may encounter is moss on your roof.  Moss or mildew can be a pesky issue, not just for its appearance, but also for the potential damage it can cause to your roof over time. But don’t worry! RST Roofing and Renovations is here with the ultimate guide to moss removal, ensuring your roof stays pristine and moss-free for years to come.

Why You Don’t Want Moss On Your Roof 

You may be wondering why moss is a problem, especially since it’s harmless out in nature. Moss grows and thrives in areas that are damp and shaded, and sometimes these areas include your roof.  While it detracts from the appearance of your roof, moss also retains moisture which slowly causes the roofing material underneath it to deteriorate. This will call for a repair or replacement of the roofing materials if the moss is not removed.  Overall, removing moss is essential to maintaining the integrity and longevity of your roof. 

How Do You Get Rid Of Moss On Your Roof?

Now that we know why moss is harmful to a roofing system, let’s go over some of the steps you can take to get rid of moss on your roof. 

Gather All The Materials

Before you get on a ladder and start cleaning your roof, it’s essential that you know what materials you’ll need during the process. Below is a list of items you will need: 

  • Garden hose with a spray nozzle
  • Soft-bristle brush
  • Moss remover
  • Protective gear (gloves, goggles, and mask)
  • Ladder

Start With Preparation

Now that you have all the tools you need, one half of the preparation is already done. Before you begin the moss removal process, ensure your safety by wearing appropriate protective gear. This includes gloves to protect your hands, goggles to shield your eyes, and a mask to prevent inhalation of any chemicals or debris.

Now, set up the ladder and check that it’s secure. If you have a harness, this is the time to use it. If you do not, ensure you have a friend or a family member with you for your safety. 

Wet the Roof:

Carry the materials to the top of your roof in a bag. If you’re dealing with larger items, have someone hand them to you while you are on the roof. 

Start by using a garden hose fitted with a spray nozzle to thoroughly wet the mossy area of your roof. Dampening the moss helps loosen it from the surface, making it easier to remove.

While you spray water on your roof, keep in mind the following things: 

  • Always spray the water in a downward direction, from the top to the bottom. 
  • Do not keep the sprayer too close to the shingles. 
  • Make sure to use gentle pressure to avoid damaging the roofing material.
Removal of Moss from the Roof

Gentle Scrubbing:

After wetting the moss, take a soft-bristle brush and gently scrub it off the surface of the roof. Use gentle, circular motions to avoid damaging the shingles or tiles. A gentle scrubbing action helps dislodge the moss without causing harm to the roofing material underneath. Be thorough but careful during this step, ensuring you remove as much moss as possible.

Apply Moss Remover:

Choose a high-quality moss remover specifically designed for roofs. Read and follow the manufacturer’s instructions carefully. Typically, these solutions need to be mixed with water. 

Use a sprayer or a suitable applicator to apply the moss remover over the remaining moss on your roof. Allow the detergent to sit on the moss for a duration of time provided by the product instructions.  You can find the best moss-removing solutions in a nearby store or local Home Depot.

Rinsing The Roof 

Once you have scrubbed off the moss and applied the moss solution, it is time to rinse the roof thoroughly with clean water. Use the garden hose to wash away any remaining moss residue and detergent. Make sure to rinse the entire roof, not just the areas where you applied the moss killer. Rinsing is crucial to remove all traces of the detergent.  

Post-Removal Inspection:

After completing the moss removal process, perform a thorough inspection of your roof. Check for any signs of damage or areas that might need repair. Address any issues promptly to prevent future moss growth and maintain the integrity of your roof.

By following these steps meticulously, you can effectively remove moss from your roof, ensuring its cleanliness and longevity.

How Do You Keep Moss From Growing On Your Roof?

While getting rid of the existing moss and algae on your roof is important, what’s even more crucial is keeping them away permanently. So, how do you stop moss from growing on your roof? Here are some things you can do!

Regular roof inspections: 

Schedule regular roof inspections to catch signs of moss early and take preventive measures promptly.

Install Algae Resistant Shingles: 

Most architectural roof shingles from leading manufacturers, such as GAF and Owens Corning, now come equipped with algae-resistant technology. 

Trim Overhanging Branches: 

Overhanging trees provide shade and moisture, which are ideal conditions for moss growth. Trim branches back to allow sunlight to reach your roof.

Install Zinc or Copper Strips:

When installed along the ridge of your roof, zinc, and copper are types of metals that gradually release chemicals that deter moss growth.
