Have you ever noticed those unsightly black streaks on your roof?
More than just a visual nuisance, these marks are caused by algae growth, which specifically targets the limestone commonly found in asphalt shingles. Thriving in moist, shaded areas, the algae hold moisture against the roof's surface, causing your shingles to deteriorate and potentially lead to leaks. This moisture retention can significantly shorten the lifespan of your roof. Regular and proactive roof maintenance is essential to prevent these algae from taking hold and to address any potential damage early.
Golden A Pro Tip: Consider installing zinc or copper strips at the ridge of your roof. These metals release particles that help prevent algae growth when they are washed down the roof by rain, an effective and low-maintenance way to protect your roof year-round.
