Those black streaks are algae, common here due to humidity. A professional soft wash is the safest method, as pressure washing can damage shingles and void warranties. We use specialized, eco-friendly cleaners to remove the algae and apply preventative zinc strips to inhibit future growth, protecting your roof's curb appeal and lifespan.

Some granule loss is normal, especially after a new roof settles or a severe storm. However, excessive loss in Gaithersburg's weather can signal aging shingles or storm damage, leaving the asphalt layer exposed. We offer free inspections to assess the extent, determine if it's a repair or replacement issue, and provide a clear, honest recommendation.

We always aim for the most cost-effective solution. For localized damage from a fallen branch or isolated granule loss, a precise repair is often sufficient. We'll match materials and color to blend seamlessly. However, if the damage is widespread or the roof is near the end of its life, a replacement may be the smarter long-term investment for your Gaithersburg home. We'll explain all options.
