Northern Exteriors Minnesota Inc | Roofing Services in Cottage Grove, MN 55016

In our Minnesota climate, skylight seals and metal flashings can deteriorate from freeze-thaw cycles and moisture. For skylight leaks, we perform a thorough inspection of the sealant and integration with the surrounding roof system, often recommending a reseal or a full skylight replacement if the unit is aged. For corroded flashing, which is common around chimneys and roof valleys, we remove the compromised material and install new, corrosion-resistant flashing, ensuring it’s properly sealed to prevent water intrusion. Our 23 years of local experience means we’re familiar with these specific challenges in Cottage Grove homes.

Our process begins with a detailed, free inspection to assess the condition of your existing roof. We then provide a clear, competitive estimate with no high-pressure sales tactics. Once you approve, our VSI-certified crew handles the job with a focus on safety and minimal disruption. We strip the old roof, inspect the decking for damage, and install high-quality underlayment and shingles, paying special attention to critical areas like valleys and penetrations. We keep you informed throughout the project and ensure a thorough clean-up, aiming for a result that provides lasting protection and adds to your home's value.
