John Sluss Roofing - Winston Salem's Top-Rated Roof Repair

Those dark streaks are typically algae stains, often called Gloeocapsa magma, which thrive in our humid climate. It's not just dirt—it can degrade shingles over time. We perform a professional cleaning using specialized, roof-safe solutions to remove the stains without damaging the shingles. For a longer-term solution, we can discuss installing algae-resistant shingles on your next replacement.

Flashing is the metal barrier that seals roof joints and valleys, and it's your first line of defense against water intrusion. Our local rain and temperature swings can cause flashing to corrode or loosen. Key signs of failure include rust spots, visible gaps, or water stains on interior ceilings near chimneys, vents, or skylights. We inspect and repair or replace corroded flashing to prevent costly interior water damage.

Our thorough inspection focuses on the extent of damage from issues like widespread algae (which can shorten shingle life) or multiple failing flash points. We assess the age of your roof, the condition of the decking underneath, and the concentration of problems. Often, localized issues can be repaired. However, if damage is extensive or the roof is near the end of its lifespan, a replacement is the more cost-effective, long-term solution for your home's protection.
