The black stains are typically a type of algae called Gloeocapsa magma, which thrives in our humid climate and feeds on the limestone filler in asphalt shingles. Shingle curling is often caused by moisture trapped underneath from poor attic ventilation or aging materials. Both issues are common here and can compromise your roof's integrity, so it's wise to have them inspected promptly.

In many cases, a professional cleaning and treatment can effectively remove algae stains and prevent regrowth, saving you from a premature replacement. Our team will assess the underlying shingle condition during an inspection. If the stains are superficial and the shingles are otherwise sound, we can clean and apply a preventative treatment to restore your roof's appearance and protection.

Prevention starts with addressing the root cause. For algae, we use zinc or copper-treated strips during repairs, which inhibit future growth. For curling, we ensure proper attic ventilation and may recommend upgraded, algae-resistant shingles designed for our local weather. Our goal is to provide a lasting solution that protects your Newport home for years to come.
