Licensed Roofing Services in Knoxville, TN 37932 - Prestige Roofing

The black streaks you see are actually a type of algae common in our humid climate. While DIY solutions exist, improper cleaning can damage shingles. We use a professional, low-pressure wash with an EPA-approved algaecide solution that safely eliminates the stains without harming your roof's granules or voiding manufacturer warranties, giving you a clean, protected roof.

Flashing separation is a frequent issue in Knoxville due to our significant temperature swings, which cause the roofing materials and your home's structure to expand and contract at different rates. This constant movement can break seals and pull nails. Our repair process involves removing the compromised flashing, resealing the area, and reinstalling with techniques and materials designed to accommodate this movement for a durable, weather-tight seal.

Absolutely. Addressing algae isn't just about looks—the organism can trap moisture and accelerate granule loss. Repairing separated flashing prevents water intrusion that can lead to rot, mold, and insulation damage in your attic. By proactively managing these Knoxville-specific problems, we help extend your roof's lifespan, protect your home's structure, and prevent much costlier repairs down the line.
