What If The Moss Grows Back

How To Remove Roof Moss – And Keep It Away

If the moss does return, do not rely on harsh chemical treatments or dry spells to kill it. Chemical treatments may harm shingles as well as moss, creating a more significant problem. Dead moss must still be removed by hand, or it will impede the flow of water off the roof and create issues. It may cause standing water. It may also clog gutters or allow for leaks.

Can You Remove Roof Moss With Detergent Or Bleach

Common bleach and detergent may suffocate and clear off some of the moss from your roof but cannot completely clear it. You need commercial-grade bleach and strong detergent to remove moss from roof surfaces. But what most homeowners do not consider is the damage these two agents have on the roof shingles.

Roof shingles primarily have a fiberglass layer with an additional protective layer of tar and asphalt. This protective layer keeps the shingles intact in the face of harsh external factors like sunlight, wind, and water. Using strong bleach and detergent will rid you of the moss issue and leave your roof shingles vulnerable as they degrade the protective layer.

Bottom line, if you want to protect your roof, avoid using strong detergent or bleach to remove moss.

How To Remove Moss From An Asphalt Roof

Q: We have a green roof that is not meant to be green. Moss is collecting on one side of the asphalt roof. The roof is otherwise in good shape. What I have learned so far is that the roof should not be power-washed. How should one remove the growth, and who does this type of work? I am not interested in getting on the roof myself.

Falls Church

A: The Asphalt Roofing Manufacturers Association distinguishes between moss, a plant with leaves that can grow into thick clumps, and mold and mildew, which are common names for types of algae that simply discolor the surface. Algae creates ugly black or brown streaks but doesnt damage a roof. Moss which is what shows in the pictures you sent is more worrisome because it can damage asphalt shingles. A thick growth of moss works like a sponge, keeping the roofing damp for long periods, and it can lift edges of shingles, making them vulnerable to blowing off in a windstorm.

To clean either algae or moss, the association recommends putting on protective gear and protecting plants, spraying with a 50-50 mix of household bleach and water, allowing that to sit for at least 15 to 20 minutes and then rinsing with low-pressure water. The bleach will kill the algae or moss, but rinsing wont necessarily leave the roof sparkling clean. Algae will disappear and wash away with subsequent rains, the association advises. Moss will loosen over time and may be removed with a leaf blower.

    Should You Remove Moss

    Why it is Important to Do Roof Cleaning and Moss Removal

    When you get a roof replacement, you may want to have your roofers install the new roof over top of the old. In certain circumstances, this can help you save money. However, if your old roof has moss growth, can you still use this method?

    You may need to deal with the moss before the full roof replacement. Your roofers will need to remove all the shingles on your old roof, or they may need to remove the largest chunks of moss with a pressure washer and then apply the new roof. It is only advisable to use a pressure washer because you no longer need to worry about the condition of the old roof. The new one will offer the protection your home needs.

    Never Pressure Wash Your Roof

    This is something VERY IMPORTANT to take note of! Never ever pressure wash your roof, because pressure washing is designed for surfaces that can withstand high impact, but the material that roof shingles are made out of are delicate and only can absorb so much pressure!

    Pressure washing can cause heavy damage by removing roof shingles from the roofs surface and further exposing it to the elements that will create more opportunities for moss to grow and spread. Dont create more problems than you started with!

    Gently Brush And Use A Water Hose To Loosen The Moss

    Get to the top of the roof using a sturdy ladder. Put on all your protective gear and bring all the necessary tools, including the moss removal treatment.

    Hose off the area with plain water at standard pressure while pointing downwards. Use a soft brush to scrub the moss loose from the shingles gently.

    How To Prevent Moss On Roof

    Happily, there are preventive measures you can use to keep your roof moss-free. First, let the sunshine in! Trim branches overhanging your roof, keep gutters free of debris, and regularly remove moisture collectors, such as leaves, branches, and seedpods, that pile up on the roof and encourage moss to grow. The best long-term solution? Attach strips of zinc or zinc-coated metal flashing strips just below a roofs peak or ridge caps. When it rains, water flows over the metal strips leaching out moss-retardant zinc particles, which attach to roof shingles and/or tiles to stop new moss from forming.

    Working safe, smart, and strategically guarantees your moss-removal operations will run smoothly. These prevention measures mean youll be able to stay off the ladder and roof for seasons, if not years, to come.

    Why Does Moss Grow On My Roof

    Vancouver Roof Moss Removal &  Algae Cleaning

    Moss, algae and lichen grow on your roof through a combination of two things: moisture and organic debris. The more water and the more debris, the greater the chance of moss growth. Another critical factor is the amount of shade your roof receives. A well-shaded roof prevents the evaporation of moisture, creating excellent conditions for moss to thrive.

    Moss and algae can often be spotted from the ground, but most roofs can actually support moss growth that can remain unseen for long periods of time. This is because moisture gets under your shingles and allows moss to grow out of the light of the sun. For this reason, evaluating moss growth on your roof takes more than just glancing up and taking a look.
