Kehrer Brothers Roofing West | Roofing Services in Mount Vernon, IL 62864

We start with a thorough inspection, often from the attic, to check for soft spots, moisture, and mold on the decking. For repairs, we carefully remove the affected shingles and underlayment, cut out and replace the rotted plywood or OSB decking with new, code-compliant material, and then reinstall the roofing system with proper sealing to prevent future moisture intrusion—a common issue here due to our humidity and temperature swings.

In Mount Vernon, thermal expansion and contraction from seasonal temperature extremes, combined with wind, can cause flashing to pull away from chimneys, vents, and walls. We fix this by removing the old, failed flashing, inspecting the underlying structure for any water damage, and installing new, high-grade metal flashing that is properly stepped, counter-flashed, and sealed to create a watertight, flexible barrier that can withstand our local weather cycles.

A comprehensive repair for decking rot or flashing separation involves more than a surface fix. We address the full system: securing or replacing compromised decking, installing a proper ice and water shield at vulnerable edges, applying new underlayment, and ensuring all flashing details are meticulously sealed. Our goal is to not just patch the problem but to reinforce the entire roof area against the specific moisture and wind pressures we experience in Southern Illinois.
