The exterior is one of the first things that people notice about your home. This includes the roof. Unfortunately, if you live in an area where the roof receives little to no sun, the shaded roof is the perfect environment for fungus to grow. The mold is unattractive all on its own, but the stains that can be left behind on your roof from this type of bacteria are unsightly as well. Plus, the growth of mold and mildew can cause your roof's structural integrity to weaken and eventually fail. Therefore, it is important to do what you can to keep it from growing on your roof. Here are a few tips:
1. Conduct Regular Debris Removal.
Your first step in preventing the growth of any type of fungus is to keep the roof clean from the get go. This means that you should conduct a thorough cleaning of the roof on a regular basis. Any type of debris should be removed from the roof frequently to help prevent the buildup of moisture and the eventual development and growth of fungus. You can limit the amount of work you have to do on the roof by keeping any trees trimmed that are nearby. This could also increase the amount of sun that is able to reach your roof and prevent mold from growing.
2. Scrub Away Hideous Stains.
In addition to debris cleanup, you will want to combat unsightly stains as soon as you notice them to keep them from getting worse. You can either purchase a pre-made solution from a local hardware store or you can use a diluted bleach solution. Make sure to use an old broom or brush to scrub the stains. Also, you should use your regular garden hose and not a pressure washer, as the higher water pressure can damage shingles.
3. Consider Installing Zinc Strips.
If you would prefer to limit the maintenance work that you have to do, you may want to consider having zinc strips installed. These will help prevent the growth of mold as well as staining. These strips are normally installed near the peak of your roof so that when it rains, pieces of zinc from the strip will wash down the roof to prevent the growth of mold and kill any fungus that is trying to grow.
The aforementioned tips will help you combat the growth of any type of mold on your home's roof. If you need assistance performing debris removal, roof cleaning or zinc strip installation, don't hesitate to contact a professional roofing contractor in the area. They may be able to shed some light on some area-specific ways to keep mold off of your home's roof.
