• Toledo averages 35.0 inches of precipitation per year, so storm events and small leaks both matter.
• Cold winters drive window condensation in tight homes.
• Snowmelt and freeze thaw cycles stress roof flashing and exterior joints.
• Humid summers slow drying after leaks.
• Basements can stay damp after heavy rain.
• Plumbing leaks behind fixtures can keep wall cavities wet.
