How Do I Clean My Roof? The Do’s and Don’ts
If you’re reading this article, then it’s more than likely your roof is not as crisp and clean as it used to be. In some areas your shingles look faded, in others, they look darker. So you figured it’s about time to give it a thorough wash. Cleaning it may seem like a simple enough task, but if done incorrectly, it could end up costing you hundreds, or possibly thousands of dollars of roof maintenance!
What’s on There?
Let’s start by breaking down what exactly is causing it to appear dirty or discolored. To most people, this resembles mold or some type of fungus. However, the dark strips you’re seeing are most likely blue-green algae.
If there are clumps of broad, green patches spread out all over, you’re looking at an abundance of moss growths. Moss and blue-green algae love to appear in the shaded areas of your roof, which also means it could’ve made its way into your gutters.
Now, How Do I Clean It?
With this knowledge, let’s break down some common mistakes when cleaning the mess up there, and some helpful tips.
- Do not use a pressure washer to clean your property. It could loosen your shingles and gutters, and leak to a hefty roof leak repair charge.
- Determine if your roof is safe enough to walk on; slip-resistant shoes are recommended by professionals when walking on a roof. However, do not spend too much time up there. Frequently climbing on top could damage your roof and loosen the shingles.
- Trim back any branches hanging over your home. If you expose more sunlight to it, then the algae and moss will have trouble remerging.
- Use a sprayer attached to any typical outdoor garden hose. Prepare a mix filled with equal parts chlorine bleach and water. This works especially well on asphalt shingles. After spraying the mixture across the whole top, and let it sit for 15-20 minutes before rinsing it with water.
- Do not overdo it with the mixture. In this case, less is more.
- Clean your roof on a calm cloudy day. If done on a sunny day, the bleach mixture could evaporate too quickly, lessening its effects.
In the case that you followed each of the tips correctly, and it’s still covered in clumps of moss and streaks of algae, then you will need an expert roofing contractor at this point. Waiting too long to clean your roof can make the algae and moss much more stubborn, and could lead to some costly roof repairs.
