Then place covers over any plants, patios or furniture the chemicals used to treat moss and fungi are very strong and poisonous to plant life so its important to try to prevent it from spreading or coming into contact with other surfaces. The best way to apply the chemical is by using a sprayer, as long as you ensure it does not come into contact with other surfaces. Apply as per the instructions on the package, and then leave to dry. Some chemicals require you to wash off any excess after, but be aware of the potential risks involved when the water drains off. The benefit of using a chemical is that it will prevent moss from growing for longer than just removing it by hand. Take a look at our range of moss removal products.

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.

How Do I Stop Moss Growing On My Roof

Trim tree branches from the roof area to prevent further moss growth. Keep your roof free of debris from leaves and sticks. Keep your gutters free of leaves. Zinc Strips. This is one of the safest methods to prevent future growth of moss. Nail zinc strips along the ridge caps along the peak of the roof.

Tips For Installing Zinc Or Copper Strips

Roof cleaning and maintenance tips

When installing the metal strip its crucial that you do not use nails to hold it in place this will cause leakage when rain drips down along the nail and through the roof structure. Its also essential to ensure the zinc or copper strips are lying thin and as close to the roof as possible, to prevent warping. When warping occurs, the area of the roof beneath it does not get treated by the strips because instead of running directly down the roof, it runs along the strip to a less warped area.

Whichever method you choose, its important to look at other factors that cause moss growth and try to remove these. For example, trimming overhanging trees and bushes will remove shade which moss needs to grow, and moving any satellite dishes to areas that wont create shade. The more sunlight your roof is exposed to, the less shade and moisture will be present, so the less likely moss is going to grow.

    Installing a metal strip on your roof ridge can also help prevent it. When it rains some of the molecules in the material will wash over your roof and help prevent the growth of not only moss but algae too.

    The type of shingles you have on your roof also plays a role in preventing moss from growing. Certain shingles come with copper granules, which contain properties that can prevent moss and algae growth.

    Is It Safe To Add A New Roof Over Moss

    This is the question being asked by many people who are considering adding a new roof over mossy shingle roofs.

    Most moss on roofs grow solely due to moisture accumulation.

    • They are usually found in damp shady areas that retain moisture, such as around chimneys or skylights, on north slopes of roofs, and at the bases of roof valleys.
    • This moisture can cause moss to grow in just a few years.
    • Mosses dont absorb much water, so when they are wetted by rain or dew, under certain conditions they will release this water back onto shingles below through the process called transpiration.
    • Transpiration is not only unsightly, but it may eventually damage wood structures, roofing materials, and painted surfaces.
    • When moss is removed from roofs, it can cause significant amounts of sediment to be released into the environment.
    • The remaining dead moss needs to be disposed of properly by placing it in bags or totes that are then taken to a licensed disposal site.
    • A single square foot of asphalt shingles contaminated with moss can contain up to an ounce of lichen.
    • When moss is growing on asphalt shingles, it actually prevents problems before they occur by protecting the roof surface from direct sunlight that would otherwise heat up the asphalt and cause it to reduce its ability to reflect heat away from the building.

    A new roof over an existing mossy roof will not be as efficient as it should be, and the possibility of heat build-up inside may cause mold or fungus problems.

    Maintenance Solutions

    To understand how to deal with the recurring problem of algae and moss growth on rooftops, it is important to learn what they are and how they grow and spread. Although some similarities exist, algae and moss are very different and require slightly different procedures to prevent or to remove.

    Often mistaken as mold or mildew, the black discoloration and streaks visible on many roofs across the United States and Canada are actually algae. The algae can form w here moisture tends to dwell on roof surfaces. Coastal or humid climates create the most conducive conditions for algae growth. The most common type, gloeocapsa magma or blue green algae, protects itself from damaging ultraviolet rays by producing a dark pigmented sheath. The algae discoloration typically begins as small spots then quickly transforms into streaks on the roof plane. By the time the algae is visible, it likely has been present for several months or longer.

    Moss is a non-vascular plant that obtains water through its leaves, unlike most plants that gather water through its root system. Moss must therefore have a moist environment to survive. In North America, moss tends to grow on north facing roof planes that receive less direct sunlight and stay damp longer than south facing planes. Overhanging tree branches provide additional shade and drop debris on the roof that further holds in moisture and acts as a food source for moss.

    Lush and verdant, thick moss overtaking a roof can be picturesque. giving the home a fairy tale, Hobbit-like feel. But moss does nothing else good for a roof, and if left unchecked it can lead to serious damage to your home. When roof moss gets thick enough to crowd out the shingles and creates decay, there is no turning back. At that point, the roof must be replaced.

    But there are easy ways to kill moss on your roof before the situation gets too serious. There are both liquid and dry products that will easily kill roof moss, but the more important stage is removing the dead moss from the roof after it is killed.

You can’t expect the dead, dry moss to flake off and blow away on its own.
