The presence of algae and mold are signs of a compromised roofing system. Yet, one is more damaging than the other, but most homeowners can’t tell the difference between the two.
Algae on Roofs
Algae growth on roof surfaces is characterized by a black-green hue. While not hazardous to your family’s health, algae stains can lower your home’s curb appeal. In fact, when your roof has streaks of algae growth, it is possible that other homes in area may get affected, too. The airborne spores can quickly spread across your neighborhood or even the entire town.
Algae grow when there is water present, which means that your roof is damp. While this growth can be washed away, routine maintenance is still the best way to prevent this issue from happening.
Mold on Roofs
While not as common as algae growth, mold on the roof surface spells trouble for anyone in the household. For one, it can cause health problems, particularly for those with asthma and other respiratory issues.
Mold growth occurs due to various causes, some of which involve issues inside the home. Lack of roof ventilation and insulation may facilitate the spread of the organism, which happens in areas saturated with moisture, such as the attic and other wooden components.
Maintenance remains the best solution in preventing these damaging forms of biological growth. Turn to the roofing pros of A1 Roofing & Construction. Call (401) 265-1019, or fill out our contact form to request a free quote. Our service areas include Tiverton, Newport and Providence, RI.
