This is a common issue in our area, often caused by ice dams or compromised flashing. As snow melts and refreezes at the eaves, it creates a dam that backs water up under your shingles. Our inspections pinpoint the exact entry point—often around chimneys, skylights, or valleys—and we provide targeted repairs with durable materials to prevent recurrence.

Proper ventilation regulates attic temperature, which is crucial here. In winter, a hot attic melts snow unevenly, leading to ice dams. In summer, trapped heat damages shingles and increases cooling costs. We assess your current ventilation and can install or upgrade systems like ridge and soffit vents to create a continuous airflow, protecting your roof structure and extending its lifespan.

After winter, check for missing or damaged shingles, signs of water stains in your attic, and sagging gutters. Pay special attention to areas where different materials meet, like around chimneys. However, many issues aren't visible from the ground. We recommend a professional spring inspection to catch hidden problems like lifted flashing or granule loss before they lead to costly interior damage.
