    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. It’s non-vascular, which means that moss doesn’t have roots like other plants do, and instead absorbs water from its appendages or spores. Because it doesn’t have the root structure to grow upward, it’s 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.

    Why Is Moss Harmful On A Roof

    You might not think that having moss on your roof would constitute a danger to your home, but the ability of moss to hold onto moisture is where the danger lies. A roof made permanently damp from moss may start to rot over time, and your entire roof might eventually weaken to the point that it becomes a danger to your family.

    Regular rainfall can keep the moss wet and make it impossible for the moisture on your roof to evaporate. Your roof is designed to dry in a reasonable amount of time after heavy rain, but moss can make that natural drying process impossible. Moss may retain moisture on your roof even when it doesnt rain, and its simply a humid week.

    Use A Pressure Washer

    A pressure washer isnt a great way to prevent moss growth, but it is an excellent solution for killing moss. It is perfect for moss with a shallow root, so areas with a couple of inches on a hard surfacesuch as sidewalks, pavers, or concrete.

    This is not the best option for roofs or lawns, as the pressure that loosens the moss can also break off other materials that you want to stay in place. Pressure washers can come in handy around the house and work well with vinyl siding wash, too.

    Washing Powder To Kill Moss

    A widely believed approach is that sprinkling common washing detergent powder across the moss will kill it. Then, you can just spray or scrub the dead moss off the shingles to save on expensive professional services.

    Experts from Roof Life of Oregon confirm that it is technically true that commonly available detergent will kill moss. In addition, they say, you can physically remove the treated dead moss by spraying it with a high-pressure hose or scrubbing and scraping, although this method is more complicated and expensive than it seems. It takes a surprising amount of detergent to kill moss.

    In addition, the cost of a pressure washer or other high-pressure hose adds to the expense of such a project. Furthermore, misuse of such a powerful stream of water can lead to roof damage that would be quite costly to repair.

    Install Zinc Or Copper Strips

    Preventing moss from the start is the best way to avoid dealing with its consequences. Many homeowners attest to the effectiveness of zinc strips. When it rains, water rolls over the metal and washes the roof, killing moss in its path. These strips inhibit moss from growing back. Theyre also great at preventing the appearance of black stains.

    In a few years, the strips lose their effectiveness so youll need to buy and install new ones. Copper strips also make good alternatives and can last longer than zinc.

    Premade strips are simpler to install and also look cleaner on your roof. You can purchase these strips online or at a home improvement store.

    It Can Cause Water Damage

    Even without raised shingles, it can cause water damage to your roof.

    If you have ever touched live moss then you have certainly felt how wet it is. It retains moisture to survive, but by doing so, it keeps your roof in a constant state of being wet.

    It also affects the drainage. Roofs are designed to run water towards the ground. Clumps of mossy growth will disrupt the natural drainage pattern. This can result in water pooling on the surface and soaking into your house.

    Understand Roof Moss And Damage

    how

    Cracks and crevices between roof shingles provide ideal spots for moss to grow and spread. These simple plants flourish wherever moisture collects, particularly on north-facing or tree-shaded roofs. Moss doesn’t need much light or nutrition, but moisture is crucial. In humid areas prone to foggy mornings and moderate winters, a slight dusting of moss can escalate to a serious roof problem.

    Left unchecked, roof moss grows into a thick, resilient layer. Established moss acts like a sponge, soaking in moisture from below and above, and keeping your roof constantly moist. Moss creeps under shingle edges as it spreads, prying shingles loose and letting damaging moisture reach the layers below. Damage progresses from shingles to rotten underlayments and damaged framework. Health-threatening mold can develop and travel down walls to affect living areas as well.

    Untreated moss gains a foothold in crevices and cracks as it spreads.

    Can Moss Damage Your Roof

    So whats the big deal? A little moss cant cause any damage, right? Wrong.

    A small amount of moss is harmless, but if its left untreated, it can cause significant damage and degrade the structural integrity of your roof.

    As I mentioned before, moss typically grows in the cracks between each shingle. As it grows thicker, it lifts and loosens shingles and allows water to leak through.

    Also, moss absorbs water when it rains and retains it for long periods, which can lead to mold, bacteria, and the decay of the roofs framing over time.

    Should You Remove Moss

    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.
