Cornerstone Roofing | Roofing Services in Rochester, MN 55901

We tackle ice dams with a comprehensive approach. First, we assess your attic's ventilation and insulation to minimize heat loss that melts snow. Then, we can install specialized ice and water shield along the roof's edges and in valleys—areas most prone to ice dam leaks. For homes with recurring issues, we may recommend upgrading to a metal drip edge or a roof rake system. Our goal is to create a roof system that sheds snow and ice effectively, preventing the water backup that causes interior damage.

In Rochester's climate, shingles age faster due to temperature swings, UV exposure, and hail. Key signs a full replacement is needed include widespread curling or cupping of shingles, numerous cracked or missing tabs, significant granule loss in your gutters, and multiple leaks. If your roof is approaching or is beyond 20 years old and showing these issues, patching may be a temporary fix. We provide honest evaluations to determine if a new, more durable roof is the most cost-effective, long-term solution for your home's protection.

For longevity in Rochester, we recommend impact-resistant asphalt shingles rated Class 3 or 4 for superior hail resistance. We also install durable synthetic underlayments and robust flashing systems. For areas prone to ice dams, we use advanced, self-adhering ice and water shield membranes. During a consultation, we'll discuss all material options, balancing durability, warranty, and aesthetics to fit your budget and provide the strongest defense against our local snow, ice, and wind.
