Roofers | Roofing Services in Piedmont, SC 29673

The dark streaks you see are often Gloeocapsa magma algae, which thrives in our humid climate. While it may not immediately damage shingles, it can trap moisture and shorten roof life. We recommend a professional soft-wash treatment specifically for roofs, which safely removes the stains without damaging the shingle granules, unlike high-pressure washing. We can also apply a preventative zinc or copper strip treatment to inhibit future growth.

Leaks after rain here are often due to worn flashing around chimneys, vents, or skylights, damaged or missing shingles from storms, or clogged valleys that divert water improperly. Our process starts with a precise leak detection to find the exact entry point, which isn't always directly above the interior water stain. Repairs typically involve sealing or replacing flashing, installing new shingles with proper sealing, and ensuring all roof penetrations are watertight to stop the leak for good.

Act promptly. A small leak can quickly lead to mold, damaged insulation, and rotten decking or framing, significantly increasing repair costs. Algae, while slower acting, indicates moisture retention that can degrade shingles over time. For leaks, we offer emergency tarping to prevent further interior damage until a permanent repair can be scheduled. For algae, addressing it sooner makes cleaning easier and helps preserve your roof's lifespan and curb appeal.
