What We Check During Roof Cleaning

No two roofs are alike, and each calls for its own cleaning approach. From cedar shake to metal to composite shingle, our team matches the technique to the material — no damage, no shortcuts.
  • Shingle Condition
    We inspect for missing, curled, or cracked shingles that could lead to leaks or structural problems. On asphalt roofs, we also check for granule loss, which accelerates wear and exposes shingles to UV damage.
  • Moss and Algae Growth
    We go beyond surface-level cleaning and maintenance. Our team examines the roof for deep lichen and moss growth, paying close attention to overlaps and edges, since that's where damage most often begins.
  • Drainage and Gutter Flow
    Proper drainage is key to a healthy roof. We check for clogs in valleys, debris along ridges, and problems where gutters connect, because trapped water left unaddressed can create serious issues over time.
