Moss will readily grow on our houses and in the yard just like it will grow in the wild. Though it usually starts in shady, moist sides of the home, moss can grow anywhere. In fact, one of the most common places moss growth is found will be on roof of your home.
Just drive around your neighborhood and look for any roof which features a light color tile or roof shingle. These readily hold moisture on which all types of moss will grow. The moss will appear as slightly darker section on the roof, almost like a dirt or stain, and generally doesn’t cover the whole roof. These moss stains will remain throughout the year and are both unsightly and damaging. They’ll start insignificant but over time move to the other parts of the home where they become a major concern.
Once it moves to shady sections of the home, you’ll start seeing the green moss poking out from under the tiles. And though the little bit of green you’ll be seeing isn’t unsettling, what should be is the damage it’s causing underneath the tiles. First the moss will extract water and nutrients from the tiles. But eventually it will start eating the rafters and wood supports of the roof.
MOSS SHINGLE DAMAGE
Eventually the moss will deteriorate both the shingles and the underlying structure if left untended. And though ripping out the shingles and replacing the damaged wood can be done, the moss will quickly return. In the end, you’ll need to start treating to both kill and prevent future problems.
MOSS IN THE YARD
Moss can also be a problem in the yard. This will happen as the PH in the soil degrades and drops below normal levels. Generally it will start growing in dark, shady areas with little to no sunlight. These areas will be taken over by the moss as it’s growth will effectively choke out the other plants. Grass, shrubs and trees will not be able to live once moss covers the top soil. Additionally, the soil under the moss will become compact and unusable for other plants. Simply removing the moss and trying to grow something else will not work. Once established in the yard, you’ll need to kill the moss first before trying to plant new grass or plants.
To treat the moss, you’ll need to use a special spray and apply it correctly. In some cases, some followup will be needed.
MOSS CONTROL ON THE HOUSE
When treating moss on the roof, you should first wet the area down. Next, lightly spray it down using one quart of MOSS KILLER per 500 sq/ft of roof. This product is ORMI listed so its safe to use in the yard and on the home. After spraying, uses a broom or brush to scrub the worse areas. This will help the treatment penetrate down to the moss roots. You need at least 1-2 days of no rain following the treatment for it work best. Within a week the moss should start to turn color and die. By 4-8 weeks it should be falling off the roofing. If you don’t see similar results, it means you didn’t get the treatment down enough into the moss and will need to treat again and scrub or brush it in better.
MOSS CONTROL FOR THE DECK
Moss growing on the deck should be treated the same way. First wet the area down with fresh water. Next spray the MOSS KILLER at the rate of 500 sq/ft per quart of spray. After spraying, scrub or brush the moss to insure deep penetration by the treatment. Allow the area to sit 1-2 days without rain and the moss will die within 1-2 weeks and should flake off in 4-8 weeks.
MOSS CONTROL FOR LAWNS
Lawn moss is almost a sign of something not right in the soil. The prime reason for moss growth is a low PH. Before treating lawn moss, you should correct the PH. First test the PH using a PH METER. If you find it less than normal (anything below a 6.5 should be fixed), you’ll need to apply some LIQUID LIME to bring it up quickly. Read more about this in our SOIL PH CONTROL article.

Once the PH is fixed, you may apply the MOSS KILLER. Like the other treatments, you’ll need to wet the lawn down with fresh water first. Now apply the Moss Killer at the rate of 500 sq/ft per quart. Following the treatment, lightly water it in to help insure good penetration. Now be sure you’ll have at least 2 days of no rain following the treatment and you should start to see the moss die within 1-2 weeks. After 4 weeks it should wash away and flake off. And if you’ve got the soil PH up close to 7.0, you can consider replacing or adding to the top soil and start new plant growth.
Once the moss is treated and dead, there are some things you can do to prevent future growth. For the lawn, it usually means keeping the PH up close to 7.00 and providing enough sun for plants to grow. If you accomplish this the moss won’t be able to move onto the turf.
For the home, spray every spring and fall with MOLD BLOCK. It can be applied to the roof, siding, decks and cement. Mold Block will stop the growth of mold, algae and moss where applied.
