Those black streaks are a common issue here due to our climate. While they can be cleaned, improper methods can damage your shingles. We recommend a professional soft wash treatment that safely removes the algae without high pressure. More importantly, we can install zinc or copper strips along the ridge to prevent future growth, giving you a long-term solution.

In our experience, it's often both. Overflow can be caused by clogged or undersized gutters, but also by improper roof drainage or ice dam damage in the winter. We'll inspect your entire roof system—including the drip edge, fascia, and slope—to diagnose the root cause. The fix might involve gutter replacement, adding downspouts, or correcting the roof's water-shedding path.

We advise a professional inspection at least once a year, ideally in the spring or fall. The wet winters and seasonal debris in our area can accelerate wear on shingles, flashings, and gutters. A yearly check allows us to catch small issues—like a loose shingle or a minor leak—before they turn into major, costly repairs from water intrusion.
