American Roofing Supply | Building Supplies & Roofing in Commerce City, CO 80022

In our area, flashing corrosion is common due to weather exposure. When the metal around chimneys or vents corrodes, it creates gaps for water to seep in, potentially causing interior water damage and mold. Our roof repair service involves carefully removing the corroded flashing, preparing the surface, and installing new, high-quality flashing sealed to prevent future leaks and separation.

For many Commerce City homes, extensive flashing separation or widespread corrosion often signals the need for a replacement, especially on older roofs. While we always recommend repairs for isolated issues, a full roof replacement becomes the most cost-effective, long-term solution when repairs are frequent or the underlying decking is compromised. We provide honest assessments to help you decide.

Absolutely. Regular, professional roof cleaning removes debris, moss, and algae that trap moisture against your flashing, accelerating corrosion. For local homeowners, our gentle cleaning service is a proactive maintenance step that helps extend the life of your flashing and roof overall, preventing minor issues from turning into major separations or leaks.
