Any homeowner wants to protect their home, both for pride and to maintain its value. If the shingles on your roof are exposed over the years to heat, cold, UV rays, precipitation, and general wear and tear, they will often start to turn black. This is usually a result of dirt stains, mold, or mildew. These ugly dark streaks damage the appearance of your home and reduce its market value. However, there is something you can do to solve this problem.
What You Will Need
Step 1. While you're working on your roof to get rid of the black staining, the surface is going to become extremely slippery. This is why you should put on a pair of nonslip boots and a protective hardhat.
Step 2. Securely position a ladder against your roof and carefully climb up to the top. Make sure you have a second person at the bottom of the ladder to help you if you have a problem.
Step 3. Use a garden hose to soak your roof with water. If you don't, then the cleaning mixture you're going to use may evaporate before it can do its job.
Step 4. Fill the plastic bucket with a quart of chlorine bleach, a 1/4 cup of trisodium phosphate and 1 gallon of water. Mix the ingredients together and pour them into a garden sprayer.
Step 5. Focusing specifically on the black areas on your roof, use the garden sprayer to spray on a coating of the cleaning solution. Then spray a second time onto the entire roof, including the black areas.
Step 6. Wait for 15 minutes, and then use the garden hose to rinse the entire roof with water. You want to take advantage of the pressure of the hose, so set the hose to maximum and hold it approximately 1 foot away from the shingles as you're rinsing off the cleaning solution. It's best to work your way down from the top of the roof to the bottom as you do this. Otherwise, you may simply restain sections of the roof.
Step 7. Repeat this process any time you see black stains reappear on your roof.
Note: Make sure that you keep any dogs or cats away from the sides of your home until the cleaning solution running off the roof has seeped into the soil or evaporated.
