If you see flashing separating, it's a sign of potential water intrusion, which is common here due to temperature swings and storms. Don't wait for a leak. Contact us at John's Roofing & Construction for an immediate inspection. We'll assess the damage, reseal or replace the flashing with high-quality materials, and ensure your roof's critical waterproofing barriers are intact to protect your home.

Those dark streaks are likely Gloeocapsa magma algae, which thrives in our humid climate. While it can weaken shingles over time, harsh pressure washing can damage them. We use specialized, low-pressure cleaning solutions that safely kill the algae and rinse away stains without harming your roof's integrity. We can also discuss installing algae-resistant shingles for a long-term solution.
