Algae growth is a prevalent issue affecting homes in Salem and the surrounding region, attributed to the area’s frequent rainfall and high humidity. This airborne organism thrives in the damp, shaded areas of your roof, nourishing itself on the limestone content within your shingles.
Many homeowners in Salem with heavy algae infestations mistakenly believe they need a costly roof replacement when, in reality, what’s often required is a professional roof cleaning. The visual impact of algae cannot be understated, as it can swiftly discolor your roof, resulting in unsightly black or green patches that detract from your home’s curb appeal. Beyond the aesthetic concerns, algae can also undermine your roof’s longevity and potentially void its warranty.
Roof shingles are designed with granules to reflect sunlight and dissipate heat, which helps maintain lower rooftop temperatures. Unfortunately, roofs laden with excessive algae struggle to reflect sunlight away from the house, causing them to absorb heat during the sweltering Virginia summers. Over time, this exposure leads to the shingles deteriorating due to heat stress, necessitating expensive roof repairs or replacements.
