If you live in a humid climate, you’ve probably seen the unsightly black staining that often occurs on an asphalt shingle roof after a few years. Unbeknownst to most homeowners, this common staining phenomenon is caused by airborne algae that collect on the roof and then grow in moist areas, producing roofing stains that look like black streaks. Since asphalt roofing shingles can absorb moisture and stay damp for extended periods of time, they can create a fertile environment for the growth of these algae stains and other microorganisms.

Algae, Mildew, and Mold Stain Resistant Roofing

Metal roofs are very resistant to algae, mildew, and mold stains for several reasons. First, the smooth, hard surfaces of a metal roof make if difficult for airborne debris, dust, and plant materials to collect. Also, metal roofing materials don’t absorb water, eliminating the damp,algae fertile, environment that can lead to growth. Finally, metal roofing materials can be thoroughly cleaned without risking damage to the roof. So, in addition to better protection against algae staining, a metal roof is also mold and mildew resistant. Eliminating these unsightly, and sometimes unhealthy mold and mildew stains from your roof will help ensure your home stays beautiful and maintenance-free for many years.

A metal roof is also among the safest of all roofs because of its durability and non-combustibility. Because metal isn’t combustible, metal roofing is fire-rated as Class A. In fact, when wildfires rage through housing developments, often the metal-roofed homes are the only ones left standing. If you’re considering installing a metal roof in a new construction or retrofitting an existing building with a metal roof, understanding the fire ratings can help you make an informed decision about the roof.
