Those black streaks are likely Gloeocapsa magma algae, which thrives in our humid climate. While it can be unsightly, the real concern is the moisture it traps, which can degrade shingles over time. We recommend a professional soft wash treatment specifically formulated for roofing materials. This safely removes the algae without damaging your shingles and includes a preventative treatment to slow its return, protecting your roof's lifespan and curb appeal.

Signs of potential deck rot include interior ceiling stains, a spongy feeling when walking on the roof, sagging rooflines, or missing granules in your gutters indicating advanced shingle wear. In North Little Rock's climate, persistent moisture from algae can seep underneath shingles. We perform a detailed inspection, often from the attic, to assess the decking's condition. Catching rot early is crucial to avoid more extensive structural repairs.

For long-term prevention, we often recommend algae-resistant shingles, which have copper granules that inhibit growth. Ensuring proper attic ventilation is also critical for our area, as it reduces heat and moisture buildup that algae loves. During any repair or replacement, we meticulously inspect and replace any compromised decking and flashings to create a sealed, robust system designed to withstand local weather challenges for years to come.
