Is Roof Cleaning Really Necessary?

The roof of your house is something that you rarely see up close — but you probably know that a complete roof replacement can be an expensive proposition. Because you want to get the longest life you can out of your roof, and avoid the need for a replacement before the time has come, getting your roof cleaned is important. Here are some common questions people have about roof cleaning and aspects that affect their roofs.

Why do people clean their roofs — and how often?

Mold, algae and bacteria like to grow the wood and asphalt shingles on your roof at the earliest opportunity. The black stains you may have seen on your roof are due to these invaders. During the first couple years of your roof’s life, the presence of bacteria was not noticeable because of the metal shards seeping out of the new material as it aged. This metal acts as a natural block for bacteria to thrive. The bacterium that makes a way underneath your shingles is the cause for concern, and this is where cleaning becomes needed.

Cleaning your roof regularly will give it a longer life and save you from buying a replacement instead. As to how often you need to clean your roof, the answer depends on a number of factors — such as how much shade you have, how often leaves are on your roof, and so on.

What happens if you do not clean your roof?

If you fail to get the black spots and streaks cleaned off of your roof, not only will they detract from its appearance, but this bacteria will also eventually weaken the shingles and structure of the roof. When this happens your roof becomes instable, leaky, and in need of replacement or extensive repairs. Neglecting regular roof maintenance — whether your roof is made from tile, cedar, or asphalt — will result in problems that are difficult to spot at first, but have lasting consequences down the road.

Does it matter where you live?

The climate in your location plays a big role in how often you will have to have your roof cleaned. For example, humid and warm weather conditions provide great opportunities for bacteria to thrive on your roof. Because of this, you will have to have your roof cleaned more frequently than a home in less humid conditions. Snowfall and frequent rainfall also play into how often your roof should be cleaned.

Find a reputable roofer

Protecting your investments is important, and your home is probably one of the most important investments you have. Since the roof is one of the most important structural components of the home, it should be maintained carefully. Homes are expensive to replace, and should last a good twenty years. Finding a good roofer to do repairs on your roof and regularly clean it for you will be a great decision that you can make for your house.
