Granville Roofing Repair | Fix Flashing & Ventilation | Nielsen Roofing & Repair

In our Granville climate, flashing—the metal strips around chimneys, vents, and valleys—corrodes faster due to temperature swings, moisture, and road salt exposure. We inspect for pitting and rust, then carefully remove the damaged sections. We replace them with durable, corrosion-resistant metals like aluminum or galvanized steel, sealed properly to prevent future leaks and protect your home's structure.

Inadequate ventilation lets warm, moist air from your attic condense and freeze on the cold roof deck, creating frost. This melts during thaws, contributing to ice dams that force water under shingles. We assess your attic's airflow and install or repair ridge vents, soffit vents, and baffles to create a balanced system. This regulates temperature, reduces moisture, and helps prevent these damaging winter issues.

Signs include excessive attic frost in winter, mold or mildew smell, peeling interior paint, or unusually high heating/cooling bills. From the outside, look for ice dams or damaged shingles from trapped heat. We recommend a professional inspection, as we can measure airflow and identify specific deficiencies in your system to recommend the right repair or upgrade for your home.
