Dercon Construction Services | General Contractors & Roofing in Andover, MN 55304

In our climate, roof insulation moisture and flashing corrosion are common issues that can lead to leaks and energy loss. At Dercon, we address this by inspecting the entire roof system during a replacement or repair. We ensure proper ventilation to prevent condensation, use high-quality, corrosion-resistant flashing materials, and install insulation correctly to protect your home. Our roofing installations also come with a strong 50-year non-prorated warranty for your long-term peace of mind.
