Your roof is an investment you want to last, especially since the average one costs over $11,000. Keeping your roof clean is one way to prevent algae, mold, and other problems that can compromise the integrity of your roofing and decrease its lifespan. Let’s take a moment to discuss all the potential concerns and why they’re a threat to your roofing.
Prevent Algae Growth
While you may not see it initially, algae spores can accumulate on top of your house. Over time, they form noticeable algae that appear as streaks or stains. This staining, however, isn’t merely cosmetic.
Algae degrades your roof because it can retain water. Not to mention, algae breaks down the protective granules of asphalt, compromising their integrity over time and making them susceptible to the elements. When you remove the spores during periodic cleanings, they don’t have the chance to grow and harm your roofing.
Inhibit Mold Growth
Any debris that remains on your roof hinders the area from receiving adequate sunlight. As a result, the parts underneath the sticks, leaves, and other organic material can retain moisture, creating the perfect breeding ground for mold.
Like with algae, mold affects the aesthetics of your roof by causing water stains and dark spots. Particularly if you have asphalt shingles, the mold will feed off the plant-based fillers in them. While the mold is consuming parts of the roofing, it’s deteriorating the shingles, reducing their lifespan, and making them less efficient at protecting themselves from the elements. By keeping your roof clean, mold is less likely to form.
Discourage Moss Formation
Moss thrives in damp, dark areas, which limbs and other plant material left on your roof create. Moisture remains underneath moss, and having wetness that close to your roof will weaken shingles and promote mold and algae growth.
If you have wooden roofing, the continual dampness will cause your roofing to rot. Removing debris deters moss from forming.
Decrease the Likelihood of Roof Leaks
Leaving leaves and other debris on your roof and allowing it to accumulate can interfere with your roof’s ability to drain water effectively. When water has an opportunity to pool on your roof, it can lead to sagging and damage, eventually causing your roof to leak and require repairs. The leak may also affect your attic or ceiling.
By keeping your roof free of debris, you can prevent several issues that cause your roof to wear out early or even damage the inside of your home. Plus, a clean roof — one without mold, algae, or moss — is more visually appealing.
