Tri State Paving & Waterproofing | Roofing Services in Bethesda, MD 20816

In Bethesda's climate, roof shingle curling is often caused by moisture absorption and temperature fluctuations, while algae stains (often black streaks) thrive in shaded, damp areas. We address this by conducting a thorough roof inspection to assess the extent of the damage. For curling shingles, repair or targeted replacement may be needed to maintain the roof's integrity. For algae, we perform specialized roof cleaning that removes the growth without damaging the shingles. In many cases, we also recommend installing algae-resistant shingles or zinc strips during a roof replacement to prevent future stains.
