According to — AllAboutAlgae.com, “Algae are simple plants that can range from the microscopic (micro-algae) to large seaweeds (macro-algae). Algae can grow in different ways, some types can grow using water resources, but micro-algae grow through photosynthesis. Other algae can also grow in the dark using sugar or starch, and some can even combine both growth modes.”
People living in hot and humid areas might be suffering from algae growing on their roofs. Luckily for them, there are some options they can consider to prevent algae from growing on their roofs. Having algae-resistant roof shingles is the most obvious and efficient way to deal with algae before it grows.
Algae-resistant shingles might not look any different than regular shingles, but they are designed to resist and prevent algae-growth. The most important component in making this kind of shingles is copper, which is usually added and embedded to asphalt shingles. Said copper granules protect the shingle roof completely against algae and helps it maintain its color and appearance due to the strategically embedded copper granules.
The percentage of copper that is usually used is 10 percent. This way it does not only prevent algae growth, but it also does not harm the environment, unlike zinc, which had been used earlier on for the same purpose.
Contrary to common belief, algae do not in reality ruin or damage a roof. The problem with algae is, in most cases, simply cosmetic. Nonetheless, Moss can easily get mixed up with algae, and moss can cause actual damage to a roof. The other problem algae can cause is monetary; having an algae-ridden roof can cause a huge drop in a property’s value. If a house has algae growing on its roof, the homeowner might face some difficulty in selling it or maintaining its value. To learn more about ways to keep shingles algae-free, follow this link.
