Those black streaks are algae stains, often called Gloeocapsa magma, which thrive in our humid Arkansas climate. They feed on the limestone in asphalt shingles. We don't just power wash them away, as that can damage shingles. Instead, we use a specialized, low-pressure cleaning solution that kills the algae at the root and includes a preventative treatment to inhibit its return for years.

Roof nail pops are very common here due to temperature swings causing the roof decking to expand and contract. Over time, this movement can push nails out. It is a serious issue because each popped nail creates a potential entry point for water, leading to leaks and wood rot. We fix this by carefully removing the affected shingle, driving in a new, longer nail in a fresh spot, sealing it, and replacing the shingle to restore a secure, watertight barrier.

Proactive maintenance is key. For algae, we recommend and apply preventative zinc or copper strip treatments during a cleaning service, which slowly release ions that inhibit growth. For nail pops, while some are inevitable, ensuring your roof has proper attic ventilation—which we can assess—minimizes extreme deck movement. Regular inspections allow us to catch and resecure a few popped nails early, preventing widespread damage and more costly repairs down the line.
