Nelson Roofing | Roofing Services in Grand Rapids, MN 55744

Ventilation frost is common here due to our cold winters and often inadequate attic airflow. Warm, moist air from your home rises into the attic, condenses on the cold roof sheathing, and freezes. Nelson Roofing fixes this by conducting a comprehensive attic assessment. We ensure your soffit, ridge, and gable vents are clear and balanced, recommend proper insulation levels, and may install additional ventilation to create a continuous flow of dry, cold air. This prevents ice dam formation, mold growth, and wood rot, protecting your roof's structure.

Skylight leaks often worsen in winter due to the expansion and contraction of materials during freeze-thaw cycles, which can break seals and compromise flashing—the metal strips that seal the skylight to the roof. At Nelson Roofing, our repair process starts with a careful inspection to find the failure point. We then remove old, cracked sealant, reseat or replace the flashing with ice and water shield protection, and apply new, high-grade sealants designed for our climate. This precise work stops the leak and reinforces the skylight against future winter weather.

Absolutely. We highly recommend a pre-winter roof inspection for every Grand Rapids home. Our inspection is thorough and includes checking attic ventilation for proper airflow, examining all roof penetrations (like skylights, vents, and chimneys) for seal integrity, and assessing shingles for wear. We'll provide a clear, honest report on any vulnerabilities and recommend proactive repairs. Catching small issues with ventilation or flashing now can prevent major ice dam or leak problems—and costly interior damage—once the snow flies.
