Those black streaks are likely Gloeocapsa magma algae, which thrives in our humid Pennsylvania climate. While DIY cleaning with a pressure washer can damage shingles, we use a specialized, low-pressure soft wash system with EPA-approved algaecides. This method safely eliminates the algae and its spores without harming your roof, providing a cleaner look and helping to preserve your shingle lifespan.

Signs of underlayment damage often appear inside your home before you see exterior issues. Look for water stains on ceilings or walls, especially after heavy rain, or a musty smell in your attic. From the outside, curling, buckling, or missing shingles can indicate a failing underlayment. We recommend a professional inspection, as our team can safely assess the underlayment's condition and recommend targeted repairs to prevent major structural damage.

While algae is primarily a cosmetic issue, it can trap moisture against the roof, potentially accelerating underlayment degradation. During our inspection and cleaning service, we always check the health of the critical underlayment layer. If we find localized damage during an algae cleaning, we can often perform a spot repair. For widespread issues, a more comprehensive underlayment replacement might be necessary to ensure your Trafford home stays dry and protected.
