Algae are tiny little organisms that just love to grow in moist places – like your roof. If you're noticing dark green or black streaks down your asphalt roof, chances are these are caused by algae. While algae does not really harm your roof or cause any major issues, it does not look attractive and can lower your home's value. Luckily, there are some things you can do to get rid of this unattractive slime and then keep it away for good.
Wash the roof with algae remover or bleach.
You can purchase an algae remover designed specifically for this purpose at your local home improvement store. However, if you're not too worried about ruining your clothing or potentially killing some of the grass below your home when the washing solution runs off of your roof, you can accomplish the same for a lot less by using plain, household bleach instead.
Obtain a sprayer attachment for your garden hose. Either pour the algae remover into the sprayer, or load the sprayer with a mixture of half bleach and half water.
Next, don some goggles to protect your eyes, and make sure you're wearing clothes you don't mind ruining. Climb up onto the ladder, holding the garden hose. Make sure you have someone on the ground to ensure your safety. Start spraying the roof, starting at the peak. Ensure you saturate the entire roof. If the sprayer compartment becomes empty, stop and refill it before proceeding.
Once your whole roof is wet, wait about 30 minutes. This gives the bleach or algae killer time to kill the algae. Once the time is up, spray the roof off with plain water. The algae should rinse away.
Install zinc or copper strips.
To keep algae from coming back, you'll need to hire a roofing contractor to come add some zinc or copper strips to your roof. These will be run along the peak of your roof and at various intervals down the roof's length. Whenever it rains, small particles of the metal will be washed down the roof. Algae does not like zinc or copper, so this will prevent it from growing back. As an added bonus, these metal strips should keep moss from growing on your roof, too!
Contact a roofing company in your area to learn more about algae protection and removal. If you're not confident climbing up onto the roof and spraying away the algae yourself, most roofing companies will also tackle this task for you. Contact a company like All American Roofing Incorporated for more information.Share

When I married my husband 10 years ago, I agreed to move into the ranch home he already owned. Initially, we planned to live in this house for five years and then after a few years of marriage we wanted to buy our dream home. After our wedding, many things in our lives changed. We both got different jobs. And we decided to transform the house my husband owned when we married into our forever home. To accomplish this task, we have begun a major renovation project. The first job on our list was a new roof. On this blog, I hope you will discover the best types of roofs to install on a brick home.
