You might not realize it, but investing in roof cleaning products or services is not just about having a good-looking house (though this is a nice side-benefit).
More importantly, it's about making the effort to keep up with a maintenance issue that, if ignored, can lead to bigger problems in the future. You can also hire Trusted Roof Cleaning Services in Vancouver & Get a Free Quote online.
Those ugly black streaks that you've probably noticed on your roof are a product of Gloeocapsa Magma, which is an extremely hardy kind of blue-green algae. Algae might seem innocent enough, but the truth is that if allowed to run wild it will eventually begin to compromise the integrity and overall health of your asphalt shingles.
This process of shingle infestation begins when an algae spore or group of spores, traveling through the air, lands on and attaches itself to your roof. It then begins the process of consuming the limestone filler in your shingles' granules, spreading and multiplying as it goes.
This filler material is now used by shingle manufacturers because it lowers the costs to make their products. The limestone works as a source of food for the algae and gives it the ability to expand and eventually take over bigger and bigger sections of your roof's surface area.
It might seem gross or unseemly but it's a fact that these roof stains are indicative that your shingles are literally being eaten away! If the algae growth goes unchecked for too long you'll eventually start losing roof granules, which are very important to the reflective properties of your roof.
If these surface granules are lost it usually leads to heat build-up in the attic, which amounts to higher energy costs, especially on those steamy summer days when the AC is working overtime to try to keep up!
