What usually comes to mind when we say San Antonio summers is extreme heat, intense sunlight, and high temperatures. While summer heat can absolutely take a toll on roofing materials, this year’s wetter-than-usual weather brings another concern for homeowners and business owners: excess rain and moisture damage. Heavy rainfall can put significant stress on your roof, especially if your roofing system already has small weaknesses that have gone unnoticed. Even a roof that appears to be in good condition from the ground may have hidden issues that allow water to enter over time. From residential homes to commercial buildings, understanding how heavy rain affects your roof can help you catch problems early and avoid more expensive repairs down the road.
