The best prevention starts with proper attic insulation and ventilation to keep your roof's surface temperature even. We recommend a professional inspection to identify heat loss and airflow issues specific to your home. For existing problems, we safely remove ice dams and can install heated cables or ice and water shield underlayment at vulnerable edges to prevent future damage.

Those black streaks are typically a type of algae called Gloeocapsa magma. While primarily a cosmetic issue, if left untreated for years, the algae can trap moisture and accelerate the degradation of asphalt shingles. We offer professional roof cleaning services that safely remove the stains and can apply a zinc or copper-based treatment strip to prevent regrowth common in our humid climate.

Act immediately. Water from ice dams can seep under shingles and into your attic, causing damage to insulation, wood framing, ceilings, and promoting mold growth. We provide emergency leak mitigation to stop the water intrusion and then schedule a permanent repair once the ice has melted, assessing the full extent of the damage to your roof deck and shingles.
