Leesburg Roof Repair & Replacement | Gerard Roofing | Algae & Granule Loss

Those black streaks are likely algae stains, a common issue in our humid Florida climate. While often confused with mold, it's typically a type of algae that feeds on limestone in asphalt shingles. At Gerard Roofing, we can safely clean these stains to restore your roof's appearance and prevent potential moisture retention. For long-term prevention, we can also discuss installing algae-resistant shingles on your next replacement.

Finding some granules is normal as a roof ages, but excessive loss can be a sign of accelerated wear, often from our intense Florida sun and weather. Those granules protect the asphalt coating from UV rays. Gerard Roofing provides free inspections to assess the extent of the loss. We can determine if targeted repairs are sufficient or if a section or full replacement is needed to prevent leaks and maintain your roof's lifespan.

We recommend a professional inspection at least once every two years, and always after a major storm. Florida's combination of strong sun, heavy rain, and occasional hail can cause wear that isn't always visible from the ground. Gerard Roofing's thorough inspections check for granule loss, algae growth, sealant failures, and storm damage, helping you address small issues before they become costly leaks or repairs.
