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.
Underlayment and ice-and-water shield
Underlayment is the secondary barrier beneath the shingles, and synthetic underlayment outperforms old felt. In valleys and along eaves, an ice-and-water membrane seals against wind-driven rain and, in cold climates, ice dams.
What causes ice dams and how to stop them
Ice dams form when attic heat melts snow that refreezes at the cold eaves, forcing water back under the shingles. The fix is a combination of insulation, ventilation, and ice-and-water membrane at the eaves — not just chipping ice.
Winter, freeze-thaw, and ice dams
Cold-climate roofs face freeze-thaw cycles that lift shingles and ice dams that force water backward under the roof edge. Proper attic insulation, ventilation, and eave protection are the defenses that keep winter water out.
Attic ventilation done right
A balanced ventilation system pulls cool air in at the soffits and exhausts hot air at the ridge, keeping the attic near outdoor temperature. That balance protects the shingles, prevents moisture buildup, and is often required to keep the manufacturer's warranty valid.
Snow load and roof structure
Heavy, wet snow adds serious weight, and a structurally sound roof with good drainage handles it while a compromised one doesn't. In snow country, metal roofs shed load efficiently and reduce the risk of dangerous buildup.
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
How do I prevent ice dams?
Ice dams are prevented with proper attic insulation and ventilation plus an ice-and-water membrane at the eaves, which stops meltwater from refreezing and backing up under the shingles.
Why does attic ventilation matter?
Good ventilation keeps the attic cool and dry, which protects the shingles from cooking, prevents moisture damage, and is often required to keep the shingle warranty valid.
What's the best roofing material?
There's no single best material: it depends on your budget, roof slope, climate, and how long you'll stay in the home. Asphalt wins on value, metal on longevity, and tile or slate on lifespan and looks.
