Guin Ferrell Roofing & Sheet Metal | Roofing Services in Dunn, NC 28334

The high humidity and frequent temperature fluctuations in our area accelerate the corrosion of metal flashings, especially around chimneys, vents, and valleys. When flashing fails, it's a leading cause of leaks. We inspect and repair or replace corroded flashing with high-quality, corrosion-resistant materials to create a watertight seal that lasts.

Those dark streaks are Gloeocapsa magma algae, which thrives in Dunn's warm, humid climate. Simply power washing can damage shingles. We use professional, low-pressure cleaning solutions specifically formulated to kill the algae and rinse it away safely. To prevent regrowth, we can apply a zinc or copper-based treatment at the roof's peak, which washes down with rain to inhibit future stains for years.

We always start with a thorough, honest inspection. For issues localized to damaged flashing or a few shingles, a precise repair is often the most cost-effective solution. However, if the underlying decking is compromised or the roof is near the end of its lifespan, we'll explain why a replacement is the better long-term investment for your Dunn home. Our goal is to recommend what's truly right for your situation.
