Common Questions

How can On-Top Roof & Chimney prevent ice dams and gutter blockages on my Delavan home?

We tackle ice dams—a common local issue—with a multi-step approach. First, we assess and improve your attic's ventilation and insulation to maintain a consistent roof temperature, preventing snow from melting and refreezing at the eaves. We also install specialized ice and water shield underlayment along roof edges and in valleys. For gutters, we recommend and install seamless systems with proper slope and downspouts to ensure efficient water flow away from your foundation, minimizing the chance of ice blockages that cause damage.

What causes moisture in my attic insulation, and how do you fix it?

In Delavan's climate, attic moisture often stems from poor ventilation and air sealing. Warm, moist air from your living space rises and condenses on cold roof sheathing, soaking insulation and reducing its effectiveness. Our fix involves a detailed inspection to identify air leaks and ventilation shortfalls. We then seal gaps around pipes, lights, and the attic access, and install a balanced system of intake (soffit) and exhaust (ridge or roof) vents. This creates a continuous airflow that removes excess moisture, keeping your insulation dry, your home energy-efficient, and your roof structure protected from rot.

Why is a full roofing system approach important for homes in the Delavan area?

A roof is more than just shingles. In our local weather, all components must work together. A failure in ventilation, flashing, or underlayment can lead to the specific problems we see here, like ice dams and interior moisture. Our comprehensive approach ensures every part of your roofing system—from the decking and underlayment to the shingles, vents, gutters, and chimney flashing—is installed or repaired to work as a unified, high-performing barrier. This holistic method is the best long-term defense against the seasonal challenges faced by Delavan homeowners.
