    What Causes Moss On Roof

    Moss grows well in cool, damp environments. So if moss is growing on your roof, its most likely you live in cooler areas of the country. Or it can grow in a section of your roof that doesnt receive sunlight consistently.

    Research shows that moss growing on any roof surface is more severe on roof sections shaded or periodically exposed to excellent weather conditions. This may either be the presence or absence of much sunlight on a roof surface. When a combination of shade and cool moisture on a roof surface, moss or lichens have a high chance of growing on it.

    Moss growth on roofs can be drastic, and finding ways to tackle them before they grow too much is an essential factor to consider. Regular roof maintenance is a recommended remedy to handle and eliminate the problem.

    Treat And Protect Against Roof Moss

    The best time to treat roof moss is when it’s actively growing. Moss grows very little in summer, but it kicks into high gear during fall rains, moderate winters and early spring months. Treating right before peak fall rains is perfect timing for roof moss treatments. You’ll get the best results if moss is damp, but no rain is forecast for a few days.

    If possible, remove excess moss with a rake or broom first. The upper layers of thick moss protect the bottom layer against moss killers. For pitched roofs that you can safely walk, sprinkle dry formulas along the roof ridge. Rains will wash the product down and cover the lower areas for you. For flat roofs or roofs that aren’t safe to walk on, use a liquid formula and a pump-style sprayer to cover all the roof surfaces easily.

    As moss dies, rains will wash dead moss away. You can speed the process with a broom or rake, too. To be proactive in moss control, treat your roof right before the rainy season each year. Always keep roofs and gutter free from leaves and other debris that can hold moisture in and promote moss growth.

    Keeping roofs free from moss helps avoid costly home repairs.

    By taking action to kill existing roof moss and prevent its return, you can protect your family and your investment in your home. CORRY’S Moss B Ware and Lilly Miller Moss Out! products help you take control of roof moss, enhance your home’s appeal and put an end to roof moss damage and costly repairs.

    Prevent Moss From Growing On Your Roof In The Future

    Once youve rid your roof of that pesky moss and algae, the next step is to make sure it doesnt come back.

    The easiest way to prevent roof moss is to trim any trees hanging over your house. Trees cast shade on your roof, preventing any moisture from drying. The sun is the best natural moss prevention tool. The more sunlight you get to your roof, the less moss youll have to worry about. Of course, those of us living dark in the PNW know its not always possible to keep the shade off your roof.

    Another way to prevent moss growth is to install zinc or copper coated sheet metal strips below the top ridge on both sides of your roof. While this preventative measure might be a bit more complicated, copper and zinc are both toxic to mold and can prevent it from growing even in the dampest conditions.

    If you choose to install zinc or copper sheets, its always a good idea to hire a professional roofer. Theyll ensure everything is installed correctly without damaging your roof.

    Removing Moss And Other Growth

    If you decide to take a DIY approach to clean moss off your roof, you need to take all proper safety precautions. Use a rubber footed safety ladder, and make sure you have someone to spot you. Always wear a helmet, and never walk on the roof of your house. Roofers use a safety harness and rubber-soled boots for traction. They may also install toe boards and roof brackets if necessary. If you cant address the problem from a ladder, you risk a severe injury that will cost a lot more than hiring a professional.

    If you can reach the growth from a ladder, you can try following these steps, but be warythere are several ways you can cause damage to your roof in the process.

    Overhead greenery should be limited to the leaves on tree canopies. If moss is covering your roof, it’s time to get cleaning. Moss grows in areas untouched by sun, so it can develop at a speedy pace on tree-shaded and north-facing roofs. Spreading moss can quickly adhere to roof surfaces, filling in voids between shingles and tiles, and reaching under and lifting up roofing materials. This heaving of shingles allows rainwater and other moisture to seep into your roof’s structure to cause decay and rot.

    Before you clean the moss off your roof, you’ll need to consider how you want to kill the plants and remove the dead layers. After cleaning, you’ll also need to put some defensive measures into play to prevent the moss from growing back.

    How To Prevent Moss Growth On Roofs

    How to Remove Moss from Your Roof – Step by Step Guide

    Moss grows most commonly on north-facing roofs because moisture lingers without direct sun exposure. Roofs beneath tree limbs can also become mossy because of the shade and the buildup of tree debris. Trimming tree limbs back from your house so that sun can reach the roof will hinder moss growth.

    In persistently mossy roof areas, you could attach strips of zinc or copper to the top of the roof. Zinc and copper molecules kill moss and algae. Special asphalt shingles that include copper offer another long-term solution to prevent moss growth. PJ Fitzpatrick has been in business since 1980.

    Another Less Common Occurrence Is Moss

    If you see green fuzzy stuff on your roof it is most likely moss. Moss loves cool, damp environments. If you have moss on your roof it will be commonly found on the North slopes in addition to overhanging treses or overhanging sections of the roof causing shade and allowing moisture to hang around and the moss to grow.

    Moss spores can become airborne and make their way onto roofs via wind, birds, squirrels, and other small animals, in the same way that algae makes its way to your roof.

    Once the moss spores land on a roof, they will gather in the spaces between shingles and eventually grow into thick spongy moss.

    Algae is a term for a large group of photosynthetic eukaryotic organisms. They are typically aquatic and lack the roots, stems, and leaves of other plants, though they still contain chlorophyllthe green pigments found in most plants. However, they are not plants but rather organisms also spread by spores, much like moss.

    Mold is the result of algae left too long on a roof. Algae needs perpetual moisture to exist, so they grow best in humid areas. When algae keeps the roof damp for long enough, rot can set in, commonly leading to mold growing and spreading.

    So Is Moss Bad For Your Roof

    Yes. 100% all moss, even if itâs a small patch or the width of a lawn, it can create irreparable damage to your roof if left untreated. This type of destruction can cost you hundreds or even thousands of dollars in roof replacement. But donât fret, you may not need to get an entire new roof just yet.

    First Off What Is Moss

    Mosses are a collection of tiny non-vascular flowerless plants that thrive in damp or shady conditions. Unbeknownst to many, there are seven classes and 12,000 known varieties of moss worldwide. Its non-vascular, which means that moss doesnt have roots like other plants do, and instead absorbs water from its appendages or spores. Because it doesnt have the root structure to grow upward, its a plant that grows low and spreads wide on flat surfaces.

    When moss spreads, it can envelop the surface and create a somewhat rustic look for cottages or cabins, which is why some people choose to let moss grow on their roofs. However, the consequences of allowing moss to grow wild are often not worth it.

    Faqs Removing Roof Moss

    Here are some of the frequently asked questions about roof moss removal.

    Companies charge an average of $0.20 to $0.70 per square foot. Expect to spend about $150 to $250 on professional moss removal. Depending on the moss treatment option suitable for your roof, the price can go higher or lower if the case is mild.

    During windy or sunny seasons, part of the moss growth on your roof can die and fall off. However, moss growth in wet or parts of your roof that has shade will continue to flourish until you find a viable moss removal method.

    Pressure washing your roof is not an effective moss removal method. Plus, it compromises your roofs wellbeing. High-pressure water jets can get some of the moss off the surface of your roof but can also lift the shingles and cause water damage to your roof.

    Is It Bad To Have Moss Growing On Your Roof

    Yes, having moss growing on your roof is bad. Moss typically grows well in dark, wet, and cool climates. However, moss is dangerous for your roof, whether you have tiles, composite shingles, or cedar shakes. This is because moss is wet and will give your roof constant moisture, resulting in high amounts of rot.

    Also, as moss continues to grow on your roof, it can push under tiles, shingles, and shakes, thereby pushing them to create damage on your roof. Moss also causes leaks on your roof and brings pests. When moss grows on your roof, it digs holes and has thin spots, eventually leaking. Additionally, bugs and rodents are usually attracted to moss.

    Moss also has a lot of weight, which will be subjected to your roof. A large mat of moss is surprisingly heavy, spongy, and holds a lot of water. This weight will be added to your roof and cause it to deteriorate over time. Therefore, youll be living in a house with a roof thats likely to fall at any time.

    How To Use Bleach Mixtures On Your Roof

    The following procedure is for bleach-cleaning only using JOMAX. If JOMAXis not available in your area, use a TSP mixture with bleach added.

  • Bleach mixtures can injure sensitive plants. Because it is difficult to totally protect them from the mix, spray them down with clean water before applying the mix and immediately after, whether you cover them or not!
  • Using a plastic pump-type garden sprayer, thoroughly soak the affected area with your choice of chemical. Allow it to sit for at least 5 minutes.
  • Wash off all dirt and fungus residue. NOTE: Though powerwashing was recommended for years, the industry has moved towards low-pressurecleaning due to evidence of permanent asphalt shingle damage caused by high-pressure powerwashing.
  • Allow the roof to dry thoroughly. Inspect the roof for any remaining fungus if it isslimy, or any sort of residue comes off on your hand, repeat the above steps. You must let the roof dry before a second application of mix. A second application of cleaner will not have its full effect on a damp surface!
  • If you think it wise to leave the bleach-brew on the roof longer than therecommended time, thinkagain! As mentioned earlier, long term exposure to bleach can damage most any surface, and yourroof is no exception. However, this piecemeal approach is the likelyto cause the least damage.

    How to clean moss off a roof for less than $15

    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.
