Protection From Stains and Streaking Caused By Algae
Dark stains and streaking are very common and can happen to even newly installed roofs. This is caused by a certain type of algae, and it is very difficult to remove and keep off. Furthermore, the algae feeds on your shingles compromising the integrity of your roof.
