Williams Roofing | Winston-Salem Roof Repair & Algae Stain Removal

Those black streaks are likely Gloeocapsa magma, a type of algae common in our humid Winston-Salem climate. While it may start as a cosmetic issue, it can trap moisture and degrade roofing granules over time, shortening your roof's lifespan. We recommend professional cleaning to remove it safely without damaging your shingles.

Signs of underlayment damage include interior water stains, leaks during heavy rain, or a spongy feeling on the roof deck. In Winston-Salem, temperature swings and storm-driven rain can compromise underlayment, allowing water to seep into the roof structure. A professional inspection from our team can identify hidden damage before it leads to major repairs.

Absolutely. We recommend annual inspections, especially after severe weather common to the Piedmont region. Our maintenance checks focus on gutter health, sealing around penetrations, and early detection of algae or underlayment weakness. This proactive approach helps Winston-Salem homeowners avoid costly emergency repairs and extend their roof's life.
