How To Remove Stains On Copper Roof Shingles – If you live in a home more than a few years old, then you probably have noticed dark spots on shingles. These spots are not dirt, as you might think, but actually a very hardy type of algae that loves to live (and eat) your copper roof shingles. The algae actually because some damage to your roof in the short term, but over time can wear away the newer models of shingles containing limestone filler that is “leaking” to the algae. Fortunately there is an easy way to get rid of these stains. You need a cloudy, dry day, and are careful when working on the roof.
First steps to remove stains on copper roof shingles, prepare yourself and your house. Make sure you wear old clothes that can get dirty and that will not ride up while you’re on the roof. Your shoes should have good soles that will not slip, even if the shingles get wet. Although oxygen bleach is considered”green” cleaning products, it can kill plants if applied directly (that is why you are using it on algae). Protect Sheet in the home by covering it with light plastic tarpaulins. Mix cleaning solution in the syringe pump. Oxygen bleach comes in a powder that you mix with water only. You will need to refer to the manufacturer’s specific measurements, because each mix is slightly different. Add two cups of vinegar to the mix when you are ready to mix bleach.
