Common signs include visible gaps or rust around chimneys, vents, and skylights, water stains on interior ceilings or walls, and drafts. Given our local temperature swings, flashing can expand and contract, leading to separation. We recommend a professional inspection, especially after severe weather, to catch and repair these issues before they cause major leaks.

In our Avoca climate, condensation from temperature differences between your attic and the outside air is a primary cause. This moisture reduces insulation effectiveness and can lead to mold. Fixing it involves ensuring proper attic ventilation, checking for and sealing roof leaks, and sometimes replacing compromised insulation. We assess the entire system to provide a lasting solution that improves energy efficiency.

We specialize in comprehensive solutions: thorough roof inspections to identify early signs of flashing failure or moisture intrusion, precise flashing repair and replacement using durable materials, and improving attic ventilation systems. For major issues, we provide full roof replacements with techniques and materials designed to withstand Iowa's conditions, preventing these common problems from recurring.
