Austin Storm Update: Commercial Roof Response, October 2026
The Austin storm that began Thursday, October 1, 2026 has been a heavy-rain and flooding event, not a hailstorm. For commercial buildings, that changes what to look for. The risk this week is water: ponding on low-slope roofs, overwhelmed drains, and leaks through flashing and rooftop units. Our crews are taking emergency calls now, and here is where things stand.
How the storm has unfolded so far
This was not a single violent cell. It was a front that stalled over Central Texas and sent rain through in rounds, pulling moisture from the remnants of Hurricane Polo. That pattern is harder on commercial roofs than a quick thunderstorm, because drains never get a chance to catch up between rounds.
The National Weather Service Flood Watch takes effect for Travis, Williamson and Hays counties, forecasting 2 to 4 inches with isolated higher totals.
Rain reaches Austin. A Flood Advisory covers Austin, Round Rock, Cedar Park, Georgetown and Pflugerville, with rain falling at 1.5 to 3 inches an hour in spots along I-35.
The Austin-Travis County Emergency Operations Center activates. Austin-Bergstrom sets a daily rainfall record. The City reports flooding on portions of the I-35 corridor.
The Flood Watch continues through 7 p.m. LCRA opens floodgates at Wirtz and Starcke dams to pass Llano River water into Lake Travis. More rounds of rain are expected through the day.
We will update this page as conditions change. If the Flood Watch is extended, the times above will be revised.
How we are responding right now
We have worked on commercial roofing in Austin since 2008, and our emergency line has been open around the clock since the rain arrived, and crews are working calls across Austin, Round Rock, Cedar Park and Pflugerville. Our standard is a two-hour emergency response. During a regional storm, every roofer in town gets calls at once, so we work them in order of risk and give you a real arrival window when you call, not a comfortable one.
This is the order we are working calls in:
Water entering occupied space or reaching electrical
Tenants, inventory, equipment rooms and anything near panels or fixtures come first. The goal on this visit is to stop the water and make the area safe, not to complete the repair.
Ponding loads on low-slope roofs
Standing water adds roughly five pounds per square foot for every inch of depth. On a roof with a clogged drain, that load builds fast during rounds of rain like these.
Blocked drains, scuppers and gutters
Clearing a drain is often the fastest way to take pressure off a roof that has not leaked yet. Overflow scuppers that are not working are a priority on parapet roofs.
Temporary dry-in where a permanent repair has to wait
Membrane and flashing repairs need a dry surface. Until we have one, we make the roof watertight and document what we did.
Post-storm inspections, once roofs are dry
Next week, as the rain clears, we move to full inspections for owners and managers who want a record of each building's condition.
What to do while it is still raining
- Keep maintenance staff off wet roofs, and send no one up during lightning. A membrane roof in the rain is slick, and roof edges are hard to see.
- If water is coming in near electrical equipment, clear the area and shut off power to that zone only if it can be done safely from a dry location.
- Move tenant property, inventory and equipment out of the drip zone, and put down containment.
- Photograph and video every interior leak with the time and location, and note which unit or suite it is in.
- Tell affected tenants what is happening and when to expect a response. For residential tenants in a multi-family property, Texas law ties the repair obligation to resident notice; our Austin multi-family complex roofing guide explains why that matters.
- Stay away from flooded roads and parking areas. Never drive through moving water.
What to check on a commercial roof after this storm
Once the roof is dry and safe to walk, these are the problems a heavy-rain event leaves behind. Many of them do not leak on the first day, which is why they get missed.
| Where to look | What it tells you |
|---|---|
| Standing water 48 hours after rain | That is the industry line for ponding. It points to a drainage or slope problem, and many warranties exclude damage caused by it. |
| Water lines on parapet walls | Shows how high water sat during the storm, which matters for flashing height and drain sizing. |
| Roof drains and overflow scuppers | Debris, missing strainers or a drain bowl sitting above the membrane level. |
| Seams and laps | Open or soft seams on TPO, PVC, EPDM or modified bitumen let water track under the membrane. |
| Rooftop HVAC curbs | Loose curb flashing often shows up indoors as an apparent condensation problem. |
| Penetrations and pitch pans | Dried-out filler and gaps around pipes, conduit and supports. |
| Top-floor ceilings | New tile staining near columns and walls, where water travels along the deck before dropping. |
If you see recurring ponding, read our guide to flat roof installation Austin; it explains why no commercial flat roof should actually be flat. For details, transitions and the ways a membrane is tested for leaks, see Austin commercial roof waterproofing.
One record per building
If you manage more than one property, the week after a storm is when records matter most. A storm does not affect every building the same way. Roof age, drain layout and tree cover all change the outcome. An adjuster who sees two buildings and assumes the rest match can misjudge the whole portfolio.
Our Commercial roof inspection Austin visits produce one dated report per building, with labeled photos of each roof section, every drain and rooftop unit, and interior leak locations tied to a roof plan.
What we do
- Document damage with dated, labeled photos
- Write a scope of the repair work needed
- Meet your adjuster on the roof and show what we documented
What we do not do
- Negotiate your claim or act as a public adjuster, which is a licensed role in Texas
- Tell you what your policy will pay
- Touch your deductible in any way
A word on storm-chasing contractors
After every storm, out-of-town crews arrive. In Texas, a contractor cannot pay, waive, rebate or absorb an insurance deductible. The usual method is an inflated invoice to the carrier, which puts a false claim in the property owner's name, not the contractor's. If anyone offers to cover your deductible, end the conversation.
Coverage decisions are between you and your carrier.
Where to go next
Storm questions from property owners
Did this storm bring hail to Austin?
So far we have not found hail reports for the Austin metro. This has been a rain and flooding event. If later reports show hail in your area, an inspection should check for it specifically, since hail damage on membrane and metal is not always visible from the ground.
My roof did not leak. Do I still need an inspection?
Not always. If your drains kept up and nothing is ponding two days after the rain, you may be fine. An inspection is worth it if you see water lines on parapets, standing water, new interior stains, or if the roof is older and has not been looked at in the past year.
How soon should we inspect after the rain stops?
Wait until the roof is dry and safe to walk, usually a day or two after the last round. Checking for ponding at the 48-hour mark is also the clearest way to spot a drainage problem.
Can you handle our insurance claim?
No. We document the damage, write a repair scope, and can meet your adjuster on site to show what we found. Negotiating a claim is a licensed public adjuster's role in Texas, and coverage decisions are between you and your carrier.
What areas are you covering during this storm?
Austin, Round Rock, Cedar Park and Pflugerville. Our emergency line is answered 24 hours a day.
Water coming into your building?
Call and tell us the property, the roof type if you know it, and where the water is showing up inside. We will tell you honestly when we can be there.
Storm details on this page come from the National Weather Service Austin/San Antonio office, the City of Austin, and the Lower Colorado River Authority as reported October 1 and 2, 2026, and may change as the event continues. Insurance information is general information, not legal advice; your policy and your carrier determine coverage. A two-hour emergency response is our standard, and arrival times during a regional storm depend on call volume and road conditions.
