Pflugerville storms and low-slope roofs
NOAA's Storm Prediction Center logged 86 hail reports within 10 miles of Pflugerville from 2015 through 2024, and 32 of them were 1.75 inches or larger. Large hail hit nearby in 2021, 2022, 2023 and 2024, with stones up to 4 inches on September 24, 2023. The city sits across Travis County and Williamson County, and businesses on both sides share that record.
On a flat roof, hail strikes the surface straight down. It can puncture or bruise membranes, crush the insulation boards below and dent metal edges and HVAC housings. Small surface marks can hide broken boards underneath, and wet insulation keeps feeding leaks long after the storm. With large hail four years in a row, many commercial roofs here may carry damage from more than one event.
Heavy rain from the same storms puts another load on low-slope roofs. Drains that are partly blocked can let water build up fast, and that weight stresses the deck.
Where commercial roofs usually fail
Seams and laps
Heat and building movement open them over time.
Penetrations
Pipes, vents and equipment curbs are common leak points.
Drainage
Clogged drains lead to ponding. See flat roof drainage systems.
Edges and parapets
Loose coping and edge metal let wind and water under the membrane.

Planning for the long run
Regular maintenance costs far less than reacting to leaks. Two inspections a year plus one after big storms, clear drains and a simple log of repairs go a long way. Our commercial roof maintenance plan post lays it out, and TPO vs. EPDM roofing helps if you are weighing a new membrane.
After any large-hail event, schedule a survey even if nothing leaks inside. Hidden damage to insulation boards and membranes often takes months to show up as a stain, and by then the wet area is much larger. Keep a log with the date of each storm, each survey and each repair. That record helps you budget for replacement ahead of time and gives you facts to share if you open an insurance claim, where coverage always depends on your policy and your insurer.

Frequently Asked Questions
How do I know if hail damaged my flat roof?
Surface marks may be small, so look for dents on rooftop units, drains and metal edges as clues. The real test is a survey that checks the membrane closely and, where damage is suspected, the insulation below. Photos of each spot give you a record for planning or insurance.
Is it better to repair or replace a commercial roof?
If the damage is limited and the insulation is dry, repair often makes sense. If moisture has spread under large areas, the membrane is brittle or leaks keep coming back, replacement is usually more reliable. A survey with photos and a written recommendation helps you compare.
Can roofing work happen while my business is open?
In most cases, yes. Work can be done in sections, with noisy tasks timed around your hours and clear access for customers and staff. Talk through parking, deliveries and entry points before the job starts so everyone knows what to expect.
