Those black streaks are likely Gloeocapsa magma, a common algae in our humid climate. While it can be cleaned, improper methods can damage shingles. We recommend a professional soft wash treatment that removes the algae without harming the roof's protective granules, and we can also discuss installing zinc or copper strips at the ridge to prevent future growth.

Finding some granules is normal early in a roof's life, but excessive loss is a sign of advanced wear, especially from our sun and storm exposure. Those granules protect shingles from UV rays. We provide free inspections to assess the extent of the granule loss, determine if it's impacting your roof's waterproofing ability, and recommend the appropriate repair or replacement strategy.

We recommend a professional inspection at least once a year, ideally in the spring before hurricane season and again in the fall. The combination of high heat, humidity, and seasonal storms can accelerate wear. Our inspections check for granule loss, algae growth, loose or damaged shingles, and sealant integrity, helping you catch small issues before they become major, costly repairs.
