JP Construction | Best Roof Repair in Washington, NC

Those dark streaks are typically Gloeocapsa magma, a type of algae that thrives in our humid, coastal climate. It feeds on limestone in asphalt shingles. We don't just power wash it, as that can damage granules. Instead, we use a professional soft wash treatment with an EPA-approved algaecide that safely kills the growth and includes a preventative treatment to slow its return, protecting your roof's lifespan and appearance.

Roof valleys are high-stress areas where two roof planes meet, channeling a lot of water. In Washington, heavy rain and wind-driven rain can overwhelm worn or improperly sealed valleys. We repair leaks by carefully inspecting the valley flashing and underlying underlayment. Our repair involves removing compromised materials, installing new ice and water shield—a critical waterproofing layer—and resealing or replacing flashing with precision to ensure a watertight channel for years to come.

We prioritize emergency leak calls for our Washington neighbors. We aim to provide a temporary mitigation same-day or within 24 hours to prevent interior damage, followed by a thorough inspection to diagnose the root cause—whether it's a valley issue, damaged shingles, or compromised flashing. Our goal is to secure your home quickly and then schedule a permanent, high-quality repair at your earliest convenience.
