Core Contracting | Roofing Services in Appleton, WI 54914

Appleton's freeze-thaw cycles put tremendous stress on roofing materials. Flashing, the metal strips that seal roof joints, can lift or separate as materials expand and contract. This creates gaps where melting snow and ice can seep in, leading to interior leaks and rot. We repair and re-secure flashing with techniques and materials designed to withstand our local climate.

In winter, warm, moist air from your living space rises into a cold attic. Without proper ventilation and insulation, that moisture condenses and freezes on the underside of your roof deck. This frost buildup can melt and soak your insulation and wood, causing mold and structural damage. We assess and correct ventilation imbalances to ensure proper airflow and prevent this destructive cycle.

Absolutely. Ice dams form when heat escapes into the attic, melting snow unevenly. The water refreezes at the colder eaves, creating a dam. Proper attic ventilation keeps the roof deck uniformly cold, while secure flashing at valleys and chimneys prevents water from backing up under shingles. Our solutions address both root causes, offering comprehensive protection against this damaging winter issue.
