After the Storm: A Realtor’s Post-Weather Property Checklist

Between torrential Hill Country rain, sudden flash flooding, and those highly unusual high-wind and tornado warnings rolling through the Greater San Antonio area this week, local real estate agents have had their hands incredibly full.

If you are a local Realtor with active listings, vacant properties, or homes currently under contract, your phone has likely been ringing with nervous questions from out-of-state buyers and local clients alike.

When the skies clear, the real work begins. To help you protect your clients, secure your active inventory, and walk into your next showing with absolute confidence, we at Joseph Creek Homes have put together a quick, highly actionable post-storm inspection checklist.

Before you host your next open house or walk a client through a listing, take 15 minutes to run through these essential checks.

1. The Foundation & Exterior Grading (Keep the Water Moving)

Texas soils are famous for expanding and contracting. When we transition rapidly from dry summer heat to saturated, torrential downpours, foundation grading is put to the test.

• Check the Slope: Walk the perimeter of the home. Ensure the soil still slopes away from the foundation. Intense rain can cause rapid soil erosion, creating "pooling zones" right against the concrete slab.
• Inspect the Downspouts: Make sure gutter downspouts are securely attached and extending at least 4 to 6 feet away from the home. Standing water at the base of a downspout is a primary cause of localized foundation settlement.
• Look for "Ponding": Note any areas of standing water within 10 feet of the home that haven't drained within 24 hours of the storm ending.

2. The Roof & Attic (Catch Small Leaks Early)

High winds and sudden wind-shear can lift shingles or damage flashing. Even if a ceiling looks pristine inside, a minor roof breach can slowly cause issues behind the scenes.

• Do a Ground-Level Scan: Grab a pair of binoculars (or use your phone's zoom) and look up. Are there any lifted, cracked, or missing shingles? Is the metal flashing around the chimney or roof valleys warped?
• Check the Attic: If the property is vacant, pop your head up into the attic access with a flashlight. Look for damp decking, wet insulation, or the faint smell of moisture. Spotting a small leak now saves your client from a major headache during the official buyer's inspection.
• Inspect the Ceilings & Drywall: Scan the top corners of rooms, especially around skylights, light fixtures, and window frames, for any fresh yellow or brown water-staining.

3. Windows & Thresholds (Pressure & Seals)

During high-wind events—especially near the extreme pressure changes of a tornado—driving rain can find its way through even tiny gaps in older or improperly sealed windows.

• Check the Tracks: Open the windows and look at the bottom tracks. High winds can force water past window sweeps. Ensure the weep holes (the tiny drainage slots on the exterior bottom frame) are clear of dirt and debris so water can drain out, not in.
• Feel the Drywall Below Windows: Run your hand along the drywall directly beneath window sills. If it feels soft or cool, moisture has bypassed the window flashing.
• Check Exterior Door Thresholds: Look for pooling or dampness on the hardwood or tile directly inside exterior doors, particularly those facing the windward side of the storm.

4. "Under Construction" Listings (What's Normal vs. What's Not)

If you have clients building a new home (or looking at under-construction inventory), they might panic if they see exposed framing getting drenched.

• Wood is Resilient: Reassure your buyers that modern framing lumber is designed to withstand getting wet during the construction phase. It is completely normal for a home to get rained on before the roof and house-wrap are fully installed.
• What to Ask the Builder: The key is drying time. A professional builder will always ensure the moisture content of the wood drops to a safe level (typically under 19%, though many high-quality builders look for 15% or less) before any insulation or drywall is installed.

A Quick Tip for Vacant Homes: If you are managing a vacant listing, storm humidity can get trapped inside quickly if the HVAC system isn't running. Ensure the AC is set to "Auto" and kept at a reasonable temperature (around 72–75°F) to help dehumidify the indoor air and prevent stale, musty odors before showings.
