Part of owning a home is keeping a roof in good condition. Part of this maintenance is cleaning your roof. Fortunately, this is not hard to do but it is important that you know how to clean the type of roof you have. Below is some more information about this so you can keep your roof over your head longer.
Clean Moss and Black Algae Stains on Asphalt Shingles
If you drive around your neighborhood you will likely see most homes have asphalt shingles. This is because approximately 75% of all homes in the United States have this type of roof. Some of the main reasons why these shingles are so popular is that they are durable, long-lasting, and easy to care for.
Asphalt shingles have a granular, sand-like finish that takes years to wear out. When installed, an underlayment is laid first and then the asphalt shingles installed over the underlayment. It is common for an asphalt roof to slough granules and you will likely see them in your gutter. If you clean your roof too roughly, however, you will remove too many granules and over time cause your roof to wear out.
You should only clean the roof if it has moss or black algae stains on it. You can remove these stains with a garden sprayer and bleach. You can also use a pressure washer, but you must be careful.
If you plan to use a pressure washer, set the water on low pressure so you do not disturb the granules. If your roof is under warranty, cleaning it with a pressure washer may void the warranty so check this first. It is generally not recommended to clean a roof in this way because if not done correctly you could cause a lot of damage.
Clean Dirt, Mold, and Mildew from Metal Roof
If you have a metal roof on your home you need to clean it periodically to remove dirt and mold. To clean the roof, fill a gallon bucket with water, and add one-half cup of tri-sodium phosphate (TSP) to the water and mix. You can purchase TSP at home improvement stores.
Dip a soft brush into the cleaning solution and scrub the mold and mildew areas until the roof is clean. When finished, rinse the roof thoroughly with a garden hose to remove all cleaning solution.
You can use a pressure washer set on a low setting to remove dirt from the roof. Start at the top part of the roof and work your way down. Do not hold the wand too close to the roof and spray it at an angle. You can put a mild detergent into the water reservoir, if desired. If you do, make sure you rinse the roof off thoroughly with clear water when finished.
Cleaning a roof can be dangerous so never do this alone. If you do not feel safe doing it, contact a roofing company, like Earhart Roofing Company Inc,as they clean your roof for you.Share
