Multi-Structure Storm Damage Assessment G… | Wannamaker

The storms that tore through Bandera, Uvalde, and the Hill Country this week — complete with tornado warnings and flash flooding across Kendall and Kerr counties — are a reminder that severe weather doesn't limit itself to one building on your property. If you own a ranch, a multi-building commercial lot, or even a residential property with a detached garage and workshop, every single structure needs its own damage assessment. Most people check the main house, file one claim, and never realize their outbuildings took hits that would have been fully covered.

Why Multi-Structure Properties Get Short-Changed After Storms

Here's the pattern we see constantly across San Antonio, Boerne, and the surrounding Hill Country: a homeowner calls about their house roof after a hailstorm. We inspect it, find damage, help them file. Six months later, they mention their barn roof is leaking. Turns out the same storm cracked or dislodged roofing on the barn, but nobody ever looked at it. By then, the window for filing that claim has narrowed — or the secondary damage from six months of leaking has made things significantly worse.

Insurance carriers in Texas — State Farm, USAA, Allstate, the regional carriers — generally cover all insured structures on a policy. But they don't go looking for damage you don't report. If your adjuster only inspects the main dwelling, the detached garage, pool house, or equipment barn don't get included unless you specifically request it.

Step 1: Inventory Every Structure Before You Call Anyone

Before you call your insurance company or a roofing contractor, walk your entire property and make a list. Every structure with a roof counts:

• Main dwelling. The obvious one — house, primary residence.
• Detached garages and carports. These often have different roofing materials than the house and can sustain damage that's easy to overlook.
• Barns, shops, and equipment buildings. Metal roofing on barns takes hail differently than shingles — look for dents, popped fasteners, and displaced panels.
• Guest houses or casitas. Common across Alamo Heights and Stone Oak properties.
• Pool houses and covered patios. Flat or low-slope roofs on these structures are especially vulnerable to ponding water after storms.
• Fencing and non-roof structures. While not roofing, damaged fences and outbuildings should be documented for your overall claim.

Step 2: Document Each Structure Independently

This is where most property owners fall short. You need separate documentation for each building — not one set of photos lumped together. Here's what to capture for every structure:

• Wide-angle exterior shots from all four sides. These establish which building you're documenting and show the overall condition.
• Close-up damage photos. Hail strikes on shingles, cracked tiles, dented metal roofing panels, missing ridge caps. Get close enough that the damage is unmistakable.
• Interior evidence. Water stains, active drips, daylight visible through the decking. Check attics and upper floors of every structure.
• Gutter and downspout damage. Bent gutters, granule buildup in downspouts (a telltale sign of asphalt shingle degradation from hail).
• Timestamps matter. Make sure your phone's location services and date stamps are on. Adjusters and carriers pay attention to when photos were taken relative to the storm date.

Step 3: Understand How Insurance Handles Multiple Structures

On most Texas homeowner policies, your main dwelling is covered under Coverage A, and other structures fall under Coverage B — which is typically set at 10% of your Coverage A limit. So if your dwelling coverage is $350,000, you'd have roughly $35,000 for other structures. That sounds like a lot until you're replacing roofing on a 2,000-square-foot barn and a detached two-car garage.

For ranch and commercial properties, the structure is different — each building may have its own coverage schedule. Either way, you need to report damage on every structure to your carrier. Don't assume they'll figure it out. They won't.

Step 4: Get a Professional Inspection — But Cover Everything

When you schedule a free roof inspection, tell the contractor upfront that you have multiple structures. A good inspector will assess each one separately and provide individual reports. A bad one will glance at the house and hand you a quote.

We see this constantly with storm chasers who flood into San Antonio after major weather events. They're focused on volume — get the house signed up, move on. They're not going to walk out to your barn or climb on your detached garage unless you insist. And even then, their documentation is often too thin to support a proper claim.

Different Roofing Materials Mean Different Damage Signatures

Your house might have architectural shingles while your barn has standing seam metal and your guest house has tile roofing. Each material shows storm damage differently. Hail that barely marks a metal panel can shatter a clay tile. Wind that lifts shingle tabs might not budge a properly fastened metal roof but could shift flashing on a flat roof. Your inspector needs to know what they're looking at on each structure.

Step 5: Don't Delay — Especially After This Week's Storms

The tornado warnings across Bandera and Real counties, combined with flash flooding in Kendall and Kerr counties, mean there's likely wind damage, hail damage, and water intrusion happening on properties throughout the Hill Country right now. If you're in Helotes, Boerne, or anywhere west of San Antonio, your property was in the direct path.

Texas insurance law gives you one year from the date of loss to file a claim for hail damage repair and storm damage. But the sooner you document and report, the stronger your claim. Water damage from a missed leak on an outbuilding can turn a straightforward roof repair into a structural nightmare within weeks.

The Bottom Line

Storm damage assessment on a multi-structure property isn't complicated — it just requires discipline. Walk every building. Photograph everything separately. Report every structure to your carrier. And bring in a contractor who will actually inspect all of them, not just the one that's easiest to reach.

The difference between a $8,000 claim and a $25,000 claim is often just the buildings nobody thought to check. Don't leave your outbuildings out of the conversation — they took the same storm your house did.
