Mold and Moss Control  Proper roof maintenance could have saved this roof. Unfortunately, the owner will most likely need to replace these much neglected shakes. Mold and mildew can be killed and cleaned temporarily with the following solution: 1 ounce detergent (e.g. Tide) 1 quart 5% sodium hypochloride (Clorox bleach) 3 quarts of warm water This solution should be applied undiluted, and the surface scrubbed with a soft brush. When the surface is clean, it should be rinsed thoroughly with fresh water. Care should be taken not to spray vegetation. If it does happen, rinse the plants thoroughly with fresh water. Moss control In dry weather, control of moss can be accomplished by spraying or brushing the roof with a 10% solution of zinc napthanate. The moss absorbs the zinc oxide and eventually can be swept off the roof. A solution of household bleach (sodium hypochlorite) mixed in a ratio of one part bleach to four parts water should prove to be equally effective. Caution should be exercised in the use of all chemicals because of their high toxicity. Generally there is no hazard to plants provided that the chemicals do not contact the surrounding soil. If this should happen, either by direct contact or by the chemicals running through a septic tank and into the soil, no vegetation may grow for some time since the soil may be sterilized. Zinc strip for moss control The use of a zinc strip nailed over the ridge or about 2 or 3 rows down from the ridge cap and about every 10 feet thereafter, has proven effective for moss control. The zinc strips should run the full length of the roof and have a portion exposed to the weather. The reaction between the rain water and the zinc forms a dilute chemical solution that is carried down over the roof and retards formation of moss, fungus and mildew.
