Why Is My Roof Leaking If the Shingles Look Fine? in San Antonio

Why Is My Roof Leaking If the Shingles Look Fine? in San Antonio
Quick answer: Most leaks start at flashing, valleys, and penetrations rather than the open shingle field, and a leak can travel far from where it enters.

For homeowners across the San Antonio metro, a roof isn't a generic product — it has to stand up to what San Antonio actually throws at it. Near the Alamo, the River Walk, the Hill Country to the north, and the sprawling Stone Oak and Dominion areas, Trophy Exteriors builds and inspects every roof for local conditions, not a one-size-fits-all checklist.

What San Antonio weather really does to a roof

Roofs here contend with hot summers, hard-water minerals, and a notorious hail alley overhead. San Antonio sits in a hail alley so active that the April 2016 storm became one of the costliest in Texas history, and large, damaging hail returns most springs. That history is exactly why the biggest local threat — some of the most frequent large-hail events in the country — shapes how we detail flashing, choose materials, and protect a San Antonio roof from the next event.

Chimney flashing and cricket detail

The junction where a chimney meets the roof is a classic leak source, sealed by step flashing and, on wider chimneys, a cricket that diverts water around it. Rusted or tar-patched chimney flashing is a sign the detail needs to be redone properly.

Why roofs leak

Most leaks don't start in the open field of the roof; they start at transitions, penetrations, and worn flashing. Tracing a leak to its true source, rather than just patching the stain below it, is what actually stops the water.

Flashing: where most leaks begin

The metal flashing around chimneys, vents, skylights, and wall transitions is where the majority of roof leaks start. Flashing that is rusted, lifted, or sealed with cracked caulk should be repaired before wind-driven rain finds the gap.

Permits, code, and insurance in San Antonio

The City of San Antonio requires a permit for reroofing, and the region's hard water and intense sun make material choice and ventilation especially important. In one of the country's worst hail markets, San Antonio homeowners should document damage immediately after a storm and consider Class 4 impact-resistant shingles.

Frequently Asked Questions

Why is my roof leaking if the shingles look fine?

Most leaks start at flashing, valleys, and penetrations rather than in the open field of shingles. A leak can travel far from its entry point, so tracing it to the true source is essential.

Should I repair or replace my roof?

Isolated damage on an otherwise sound roof is a repair; widespread wear, multiple leaks, or an aging roof usually calls for replacement. A professional inspection gives you a straight answer instead of a guess.

When should I get my roof inspected?

At least once a year, and again after any major storm. Catching damage early keeps a small repair from becoming an interior leak, and creates a dated record of your roof's condition.
