There are several ways to eliminate roof moss. If the moss is not too thick, it can be easily removed with a standard brush. However, you should never drag the brush across the roof because this can weaken the bond between the shingles. You can also use a pressure washer to remove large foam lumps that may form on the roof. After the foam is removed, spray the roof with water and apply a cleaning solution.
When using cleaning solutions to get rid of roof moss, make sure that you use the correct mix. A mixture of two cups of chlorine bleach and eight ounces of dish soap or other mild detergent should work well. You can buy these products at stores or make your own by following the instructions on the packaging. The cleaner solution should be left on the moss for at least 15 minutes.
Another option is to use a broom and garden hose to scrub the moss off the roof. Apply the water on the roof at an angle, so that the moss doesn’t hold on to the shingles. The moss will be easier to remove once it’s wet, but you need to be careful not to damage the shingles or damage nearby plants.
Using copper or zinc-coated sheet metal on your roof can also help. These are two metals that inhibit moss growth. They can be bought in rolls and then cut into strips of two to four inches. You can then attach the strips to your roof using a roofing nail or a screw with a rubber washer.
Using a pressure washer or a long-handled brush is another option to get rid of roof moss. However, remember to use caution because powerful water can damage asphalt shingles. You should also ensure that you are using a safe, rubber-soled ladder before attempting to clean the roof. A safety harness and rubber-soled boots are also recommended for safety. Lastly, you should always have someone spot you on the roof to prevent slipping.
Dry powder moss killers are another option. This type of moss killer works by spreading a dry powder on the roof in multiple lines parallel to the ridge. The powder mixes with rainwater that runs toward the eaves. This method should eliminate the moss in a week.
Copper-coated strips can also help to eliminate roof moss. Copper strips help dislodge copper ions that wash down onto the roof during rain. These ions create a poisoned environment for the moss. This is further dislodged by the ultraviolet light from the sun. The UV light contains powerful photons that are capable of dislodging copper ions.
Moss can be extremely damaging to your roof if you do not treat it properly. A mossy roof can absorb water, and this moisture can eventually damage the roofing shingles. In addition, the moss may also cause cracks in the shingles.
