What Happens to Your Roof When It’s Not Regularly Cleaned?

As a homeowner, you have many maintenance tasks and chores that need to be taken care of regularly. Without routine maintenance and cleaning, certain parts of your home will be at a higher risk of being damaged or may need to be replaced sooner than necessary. One such part of your home is your roof.

Cleaning your roof is an important part of caring for your home. When you don’t clean and care for your roof, you run the risk of endangering your home and incurring costly repairs.

What Happens to Your Roof When It’s Not Regularly Cleaned?

Damaged Roof Shingles

When dirt, bacteria, and algae are allowed to grow on your roof, your shingles will sustain damage. Dirty roofs make the perfect home for aggressive moss and algae growth, which, if left unchecked, can cause irreversible damage to your shingles.

When roof shingles are damaged, your roof becomes more vulnerable and less effective at protecting your home.

This may lead to increased power bills, and more heat being let in during the summer and let out during the winter. This can also cause water damage as rainwater and storm debris find their way into your home and around the shingles. Additionally, you’ll also face the risk of structural damage or wood damage if the vulnerable area is left unchecked.

Mold and Mildew Growth

Mold and mildew love to make their home in moist places. If your roof is dirty, water is more likely to get trapped and create the ideal habitat for mold and mildew growth. Since these growths are rarely in easy-to-see places, it can quickly get out of control. 

Mold and mildew present a serious health hazard to you and your family. Even if it isn’t clearly visible, mold that grows on your roof may creep down into your walls and cause allergies or other health issues without you knowing.

Shorter Lifespan

When your roof isn’t well cared for, it’s harder for it to withstand damage and keep your home safe. Over time, this additional strain will shorten the lifespan of your roof and lead to you needing to replace your roof much sooner than you planned. 

Many people put off cleaning their roofs because they fear it will be costly. However, if their roof isn’t cleaned, they’ll end up needing to replace it, which is much more expensive in the end. In the long run, cleaning your roof regularly will be the more affordable option as you won’t need to replace your roof nearly as soon after the last replacement.

Reduced Property Value

When your roof isn’t clean, your home won’t look nearly as nice. Your curb appeal will drop, and your home will lose value as your roof becomes more vulnerable and run down. 

Even if you aren’t planning on selling your home, it’s crucial to keep your roof clean so that the value of your property stays up and you have a home that you can be proud of. 

Pest Infestation

You may not realize it, but a dirty, overgrown roof makes a great nest for insects, rodents, and other creepy crawlies. While they get comfortable on your dirty roof, you’ll be wondering why you suddenly have more bugs or pests in your home and how to get rid of them. The last thing you’d want is a major pest infestation in your home to deal with.
