How To Prevent Roof Moss Reoccurring
Moss growth is a common recurring problem that many homeowners grapple with. Its annoying when you have to call the experts to help remove roof moss every couple of months. Aside from using harsh chemicals and buying copper to keep moss from re-growing, there are some inexpensive solutions you must try. They include:
How Moss Ruins A Roof
In general, it is north-facing roof areas that receive little sunlight that are prone to mossespecially when the overall climate is cool and damp. But even in damp climates, roof areas that receive even a little strong sunlight each day may not develop moss. You are most likely to find it on areas of the roof that are shady nearly all the time, such as roof areas beneath heavy tree canopies.
Roof moss begins with a thin dusting of green that you may notice only from low angles. This thin layer on the top of the shingles gradually expands and becomes wide, thick, and mat-like. The seams between the shingles and the shingles’ edges also develop moss because they tend to be especially shaded.
As moss thickens, it works its way under the shingles and raises them up. If the shingles are wood, this process can happen at an alarming ratewood’s porous surface is prime real estate for moss growth. Once moss has adhered to wood shingles, it is much harder to remove than from the relatively smoother planes of composite or asphalt shingles.
Once the moss is a thick mat, it becomes a sponge that soaks up and retains all moisture. This stored water quickly works its way under and between shingles and then onto the lower levels of roofing felt and the structural elements of the roof. This eventually leads to rot, and rot leads to further decay of roofing materials. The accelerating cycle can even destroy a roof in a matter of a few months.
How You Shouldn’t Remove Moss From Roofs
While there is a right way to remove moss from the roof, there are also wrong ways to go about it.
A common misconception about how to get moss off a roof is that people tend to consider is using a pressure washer. A pressure washer tends to put too much pressure on roofs, which can damage your shingles. Most people aren’t properly trained to use them, which might cause more harm than good.
Scraping is also not something you should consider when trying to figure out how to get rid of moss on the roof, as it can also cause damage to the shingles. Since moss can deeply attach itself to your shingles, you might end up lifting shingles too much and causing cracks in them.

Some moss killers available from hardware stores and online arent the best for the environment, but unfortunately, there are no all-natural products that work quite as well.
Some websites recommend using chlorine bleach or dish soap for roof cleaning, but these products are also not great for the environment and dont work well for roof moss removal. The best thing you can do is mitigate the damaging effects the dedicated moss killer products have on the ecosystem.
One thing you can do to protect the environment while using moss killers: disconnect your downspouts and route any runoff to your lawn. This will help keep the chemicals out of storm drains and prevent them from contaminating water bodies and drinking water.
You can also choose more environmentally friendly products, like those that dont contain zinc or copper. Zinc and copper are toxic to many animals, so choosing a product without them is a good option overall, especially if you have pets or children in your home. Sodium percarbonate is an effective and environmentally friendly moss remover contained in some of the products we outline above.

How Do You Stop Moss From Growing On Your Roof
As we have discussed, it is important to remove any moss that grows on your roof, as it can affect your roof in many ways. But, after you have removed it, is there any way to prevent it from growing back? Or, at least slow down the process? Yes. There are a number of steps you can take.
After you have cleaned your roof, or have had it professionally cleaned, you want to make sure you get it treated with an anti-moss biocide, or with sodium hypochlorite. This will not only kill existing moss, but it can prevent moss from growing in the future. Leaving this treatment on your roof will keep it clean and moss-free.

Another step you can take in preventing moss growth on your roof is cutting back overhanging trees if possible. Trees with branches that hang above or near your roof can cause a great deal of moss to grow. They provide shade from the hot sun, and years of falling debris can cause an optimum environment for moss to thrive. Dead leaves, twigs, dirt, and other things dropped by birds can build-up on your roof. So trimming overhanging branches regularly can make all the difference in stopping moss from growing.
Regular Roof & Gutter Cleaning
You should clean your roofs periodically to remove any accumulated organic dirt and debris. This will help prevent moss growth because moss depends on such for its growth.
Accumulated dirt debris can also hold water thus adding another growth factor for moss and thus should be removed regularly as needed.

Why Is Moss Growing On My Roof
Moss is a type of non-vascular herbaceous plant that grows rapidly on many surfaces. It starts its life as spores that are carried by the wind, or even birds, and can land on your roof and other surfaces.
Moss attaches itself to any organic material that is available, and uses this as its anchor, or base, for growing. Moss growth is far more likely on damp, cool surfaces that dont receive much sunlight
Below are some of the things on your roof that could be causing the growth of moss:
Moisture Moss requires a relatively damp environment to grow, but it will not thrive in a swampy environment. The gaps beneath and between shingles are frequently damp and provide the moisture moss required to grow.
Dirt and organic debris Debris from fallen leaves on the roof and dirt act as an ideal food source for moss, providing anchorage and even holding the moisture required for growth.
Shade Moss prefers to grow in the shade, which makes sense because moisture tends to linger in these areas, making the moss less likely to dry out quickly.
Choose Effective Roof Moss Controls
