Those black streaks are likely Gloeocapsa magma algae, common in our humid climate. While it can be cleaned, improper methods can damage shingles. We recommend a professional, low-pressure cleaning with an EPA-approved solution that kills the algae at the root and helps prevent its return. For a long-term fix, we can discuss installing algae-resistant shingles on your next replacement.

In most cases, yes. Flashing—the metal seals around chimneys, vents, and valleys—is a common failure point for Sheridan roofs due to thermal expansion and contraction. A compromised seal allows water in. We'll inspect the flashing for cracks, corrosion, or separation. The fix typically involves carefully removing the old material and installing new, properly sealed flashing to create a watertight barrier.

We recommend a professional inspection at least once every two years, and always after a major storm with high winds or hail. Regular checks allow us to spot early signs of wear, like loose granules from shingles or minor flashing issues, before they turn into costly leaks or interior damage. It's a small investment for long-term peace of mind.
