Those black streaks are typically a type of algae called Gloeocapsa magma, which thrives in the humid climate common in Southeast Michigan. While it doesn't immediately damage shingles, it retains moisture and can accelerate granule loss over time. We can safely clean and treat these stains to restore your roof's appearance and health.

Signs of underlayment damage often appear inside your Auburn Hills home, like water stains on ceilings or walls, especially after ice dams in winter or heavy rains. Outside, you might notice curling or buckling shingles. We recommend a professional inspection, as we can identify compromised underlayment before it leads to major leaks or wood rot in your attic.

In Auburn Hills, our weather is tough on roofs. Damaged underlayment loses its waterproof barrier, allowing moisture to seep into the roof deck. This can lead to mold, wood rot, and compromised insulation, which are costly to repair. Promptly fixing underlayment protects the entire structure of your home from our freeze-thaw cycles and heavy precipitation.
