San Antonio sits in flash flood alley, where slow-moving storms can dump four inches of rain in an hour. When this happens, water overwhelms gutters and sheets off roof edges in torrents. Without drip edge, this water slams into fascia boards and splashes back under shingles. The expansive clay soil throughout Bexar County compounds the problem. As foundations shift with soil moisture changes, homes in neighborhoods from Helotes to New Braunfels experience roof plane movement that can open gaps in poorly installed drip edge systems. This combination of extreme rainfall and foundation movement makes proper drip edge installation more critical here than in stable-soil regions with gentler rain patterns.
San Antonio's roofing contractors see the consequences of missing or inadequate drip edge every day. Homes in established neighborhoods like Alamo Heights and Olmos Park that have original 1960s roofing often lack this component entirely because building codes changed. Summit Roofing San Antonio works with the specific challenges of local architecture, from Spanish Colonial Revival homes with minimal overhang to modern designs with complex roof lines. We understand how the city's building department interprets current IRC code requirements for drip edge and ensure installations meet or exceed these standards. Our familiarity with local supply chains means we source materials that hold up to Texas heat without warping or corroding.
