What Are the Most Common Weather-Related Roof Problems in Missouri?

Missouri roofs are vulnerable to several common weather-related issues that can compromise roof functionality if left unaddressed.
How Does Hail Damage Manifest on Roofs?
Hail damage appears as depressions, cracks, or loss of granules on asphalt shingles. In severe cases, large hailstones can puncture or even break shingles, creating immediate water infiltration risks. Over time, minor hail damage can open pathways for leaks, leading to interior water damage and mold growth.
What Causes Roof Leaks During Missouri’s Rainy Seasons?
Roof leaks during rainy seasons typically result from a mix of aging materials and weather-induced damage. Deteriorated flashing, improperly sealed joints, and damaged shingles that no longer provide a watertight barrier are common culprits. Clogged gutters can also force water onto the roof, stressing vulnerable areas and exacerbating leaks.
How Do Freeze-Thaw Cycles Lead to Roof Deterioration?
Freeze-thaw cycles stress roofing materials as water infiltrates small cracks and freezes, expanding by up to 9%. This repeated process gradually widens cracks, dislodges granules, and ultimately causes significant material breakdown. Homeowners in harsh winter climates may notice accelerated wear due to these cycles, making regular maintenance and eventual replacement necessary.
