GCM Construction & Maintenance | Roofing Services in Eden Prairie, MN 55344

In our climate, inadequate attic ventilation allows warm, moist air from your home to rise and get trapped. This warmth melts snow on the roof, which then refreezes at the colder eaves, creating ice dams and interior frost. GCM Construction addresses this by inspecting and improving your ventilation system, ensuring proper airflow to maintain a consistent roof temperature and prevent these damaging issues.

Minnesota's freeze-thaw cycles, coupled with exposure to moisture and road salts, can accelerate corrosion on metal flashings around chimneys, vents, and valleys. Corroded flashing loses its watertight seal. Our repair process involves a thorough inspection to identify all compromised areas, careful removal of the old material, and installation of new, high-quality flashing properly integrated with your roofing system to prevent leaks.

We recommend a professional roof inspection at least once a year, ideally in the fall. This allows us to check ventilation pathways, clear debris from valleys and gutters, and examine all flashings for early signs of wear or corrosion. Catching small problems early through routine maintenance with a local expert like GCM is the most effective way to prevent major, costly repairs from ventilation or flashing failures.
