Those common black streaks are Gloeocapsa magma algae, which thrives in our humid Maryland climate. While gentle cleaning can remove them, it's often a sign of moisture retention. We recommend a professional soft-wash treatment to safely eliminate the algae, followed by applying zinc or copper strips at the roof's peak. These strips release ions with each rain, providing a long-term barrier against future stains, protecting your roof's surface and your home's curb appeal.

Frequent gutter overflow in our area is usually due to a combination of heavy downpours, clogged downspouts from pine needles and debris, and undersized or poorly sloped gutter systems. We solve this by first conducting a full assessment to identify the root cause. Our solutions often include installing larger, seamless gutters, adding more downspouts for better water diversion, and ensuring proper pitch. We also recommend and install gutter guards specifically designed for Maryland's mix of foliage to minimize future clogs and protect your foundation.

Absolutely. Proper attic ventilation is a key defense against both algae growth and ice dam concerns that can lead to gutter problems. In Keymar's climate, a hot, stagnant attic promotes the moisture algae needs to grow and can cause snow melt-refreeze cycles on the roof edge. We evaluate your current ventilation and often recommend a balanced system of intake (soffit) and exhaust (ridge or roof vents). This regulates temperature and moisture, extending your roof's life and reducing the conditions that lead to stains and ice-related water backup.
