Algae Resistant Roof Shingles: Ugly black stains on your roof are a sure sign that you have an algae problem. Algae lives off the materials used to manufacturer the shingles on your roof. Although algae is not harmful to your roof the dark stains that it produces on your roof are very unsightly and makes your home look older than it is.
When a roof in a neighborhood is infected with algae all the other houses in the neighborhood are susceptible to algae infection as the airborne spores are carried from one rooftop to the other.
Many roof shingles manufactures are now producing algae resistant roof shingles, in a wide variety of colors to suit your home. These shingles are made with copper or zinc granules which release the metal ions to the surface of the shingles and prevent the roof from darkening.
Although these shingles are more expensive they are well worth it when you consider what it would cost to clean your roof of algae in the long term. Copper is the primarily ingredient in the new type of shingles because it stops the algae before it can attach itself to your roof.
Your roof will be constantly protected from algae with this new type of shingle and when it rains the algae resistant shingles will be further activated, as the rain will distribute the algae fighting component even further along the surface of the roof.
Here are some manufacturers of Algae Resistant Shingles:
3M's Scotchguard Algae Resistant Roofing Systems - is designed with algae stopping copper granules which are evenly distributed over the roof for optimal long term algae and stain resistance. These algae resistant roofing systems comes in four colors; Grey, Red, Black and Light Grey.
