Dark spots on a roof and streaking on Columbus roofing can be caused by several different things.
The major reason is algae.
Black algae spores spread by wind from place to place, just like dandelion seeds. When algae lands on a “friendly” roof – one that’s warm and moist with asphalt shingles containing crushed limestone, an excellent food source – they begin actively growing. When the roof dries out, the algae goes dormant and discolors. Unsightly dark stains remain that can really detract from your home’s curb appeal. If left unchecked, algae problems can even cause the shingle to deteriorate and leak.
Algae Stains and Dark Spots On A Roof
Most shingles now have algae-resistant products on them, but only last 10-12 years. So as a roof ages out, it becomes more and more discolored as the algae takes over the roof. This is not only a sign that your roof may need replaced but also might be a sign that you have other issues, like trees overhanging the roof, a major shaded area from another structure blocking the sunlight, or simply a worn-out roof.
Muth & Company Has Solutions
Muth & Company offers algae-resistant shingles from GAF in a variety of colors to compliment your home. The concept behind algae-resistant shingles is quite simple. Copper or zinc, one of the main ingredients in this type of shingle, poisons algae so it’s unable to survive on the roof surface. The metals present in algae-resistant shingles are further activated by rain, which distributes the poison along the roof’s surface.
These shingles do cost a bit extra, but are well worth the money. Especially if you find dark spots on a roof and algae staining bothersome. This can save you time and money to pay for frequent cleanings.
