Gusts around 50–59 mph hit the San Antonio area this spring. Local outlets reported toppled fences and damaged shingles, and roofers saw a surge in calls within days.
Wind alone can lift shingles. Poor installation makes it worse—especially at the edges of the roof where uplift is strongest. IBHS notes that starter strips at eaves and rakes help resist edge uplift; missing or mis-installed starters, or shingles that are never sealed, are common failure points. Improper nailing (too high, too few, or over-driven) also weakens wind resistance.
What to look for after a windy day
- Creased or missing shingles. Focus on roof edges, ridges, and near vents.
- Lifted flashing or ridge caps. Wind can pry these first.
- Wind-driven water signs inside. Stains on ceilings or walls after storms.
If you see active leaking, tarp the area and schedule a roofer. In Texas coastal windstorm areas, some permanent repairs require code compliance sign-offs (WPI-8) for insurance eligibility—ask your pro if that applies to you.
Why some roofs fail at “only” 50–60 mph
Modern shingles carry wind classifications (e.g., ASTM D7158 / D3161) that assume correct installation and sealing. Gaps like missing starter strips, cold-weather installs that never sealed, or high nailing reduce uplift resistance and make tabs easier to peel back—even in sub-hurricane gusts.
Fix now, then harden for next time
1) Repair + document.
Replace creased/missing shingles and re-secure flashing. Take date-stamped photos before and after. (Documentation helps for bids and any claim review.)
2) Verify the edge details.
Ask your roofer to confirm starter strips at eaves and rakes and to hand-seal any tabs that didn’t bond (per manufacturer guidance).
3) Check nailing and underlayment.
On re-roof or larger repairs, verify nail count/placement and consider roof-deck sealing or enhanced underlayment to limit interior water if shingles lift. IBHS’s FORTIFIED guidance outlines these beyond-code upgrades.
4) Consider higher wind-rated systems.
When reroofing, ask about shingle wind classifications and what installation steps are required to get the rated coverage in your area.
Make your records work—so bids and claims move faster
Keep permits, photos, and roof work in one place
- Property Journal (TradeCrews): Store storm photos, invoices, repair notes, and model numbers. When a contractor, HOA, or insurer asks for proof, export a clean packet in seconds.
- Jack Report™: Jack reviews your Journal entries and generates a one-pager showing roof condition, risks, and likely next steps (e.g., “edge sealing incomplete near north rake”). Share it with roofers so they price the real scope, not guesses.
When to call a pro immediately
- Active leaks or sagging drywall after wind-driven rain
- Large sections of missing or flapping shingles
- Exposed underlayment or torn ridge caps

Bottom line
San Antonio’s 50–59 mph gusts were enough to expose weak installs—and to fill contractor calendars. Edge details, nail placement, and proper sealing decide how your roof rides out the next burst. Document repairs, tighten the edges, and upgrade where it pays. The Property Journal and Jack Report™ help you bring facts to every bid and every claim.
