How Often Should You Clean Your Roof? A Complete Maintenance Schedule

While roof cleaning is not at the top of most homeowner’s to-do lists, it is vital for keeping a home in tip-top shape.

A clean roof protects against damage and reveals areas that need repairs. Roof cleaning removes moisture-prone organisms and can enhance a home’s curb appeal. Regular cleanings may be required twice yearly, depending on climate and roofing materials.

Algae Removal

The roof over your head protects your home and belongings from the elements. But your roof is exposed 24/7 to dirt, water, leaves, plants, and more.

If your home is surrounded by trees or in a rainy area, your roof may need to be cleaned more often because of the increased debris and moisture build-up. It must be removed if your roof has algae, moss or fungus. If left unattended, this growth can damage the shingles and cause leaks within your home.

A professional roof cleaning will remove the stains caused by algae, moss or fungus and help prevent this issue from returning. A roof cleaning will also be an opportunity for a professional to inspect the condition of your roof and identify any areas that might need repairs. It can help extend the life of your roof. It is a great reason to clean your roof regularly!

Debris Removal

When organic debris like leaves, pine needles, sticks, and twigs accumulate on your roof, it can cause damage. For example, they may block scuppers, leading to water build-up and leakage. Similarly, they may also cause damage to shingles and tiles by breaking their surface.

It is one of the most important reasons you should regularly clean your roof. It can raise the overall value of your house and help you avoid spending thousands of dollars on repairs for water damage.

Removing debris from the roof before it grows algae, moss, and fungi is essential. Getting rid of these contaminants before they spread is much easier than getting them out once they have already done serious damage. You can do this by yourself as long as you are comfortable climbing onto the roof, or you can hire professionals to do it for you. Doing it during and on a dry, clear day is best. Roofs are not the best candidates for traditional pressure washing because the high water pressure can harm delicate roof materials.

Energy Efficiency

Keeping your roof free of organic growth like moss, mildew and algae is vital to its lifespan. Organic growth deteriorates roofing materials.

A dirty roof can also be less efficient at keeping your home cool. It happens because a dark moss or fungus-infested roof absorbs sunlight and heats your home (like wearing dark clothing on a hot day). Your home will remain colder and more energy-efficient if its roof is clean and in good condition, reflecting UV rays from the sun.

The location of your home, roof size, season and roofing material will all affect how often you should have your roof cleaned. For example, homes surrounded by trees require more frequent cleaning to remove debris like branches and leaves. Regularly cleaning and inspecting your roof will help prevent problems such as leaks, insect infestation, mold and rot. It will also maintain your curb appeal and extend its lifespan.

Curb Appeal

The most obvious reason to have your roof cleaned is to improve the look of your home or business. Dark streaks on a roof aren’t just unsightly; they also retain moisture and can lead to mold and algae growth, damaging the roof’s structure. Moss or lichen may also void roofing warranties, so quickly getting rid of these microorganisms is important. A clean, attractive roof can increase the resale value of your home or business.

Additionally, when a professional cleans your roof, they can check it for signs of damage, such as missing or damaged shingles. It’s imperative to regularly clean your gutters to avoid the accumulation of debris that can clog your downspouts and gutters, including sand, water, leaves, and other materials. Regularly cleaning these can also guarantee that snow and water are appropriately drained during intense downpours. In the end, a well-maintained and clean roof can save you money in both energy costs and the need for costly repairs.
