Valley leaks are common here due to the heavy snow and ice that accumulates in these low points, stressing the flashing and underlayment. We fix them by first performing a detailed inspection to find the exact failure point, then replacing damaged materials with ice and water shield—a self-adhering membrane critical for our climate—and installing new, properly integrated flashing to ensure a watertight seal for years to come.

Signs include damp or matted insulation, a musty odor in the attic, visible mold growth, or stains on the ceiling below. In East Lansing, this often stems from small, undetected leaks. We recommend a professional inspection, especially before winter. If damage is found, we safely remove the wet insulation, repair the roof leak at its source, and ensure proper attic ventilation is in place before reinstalling new, dry insulation to restore your home's thermal efficiency.

The most critical step is ensuring proper attic ventilation and insulation. In East Lansing, poor ventilation leads to ice dams in winter and trapped moisture year-round, which cause the very leaks and insulation issues we see often. After any repair, we assess your attic's airflow and insulation levels. Correcting this not only protects the repair but also extends your roof's overall lifespan and improves your home's energy efficiency.
