Preparing Your Houston Home for Spring Storms: A March Checklist

March signals the start of Houston’s severe weather season. Cold fronts clashing with Gulf moisture produce powerful thunderstorms capable of hail the size of golf balls, straight-line winds exceeding 70 mph, and occasional tornadoes. Your home needs to be ready. Here’s your March storm preparation checklist.

Roof and Hail Readiness

Houston leads the nation in hail damage claims. Before spring storm season:

• Have your roof professionally inspected for pre-existing damage — this matters for insurance claims after a storm
• If your roof is 15+ years old, consider proactively replacing with Class 4 impact-resistant shingles (many Houston insurance companies offer premium discounts of 15–30%)
• Check the roof for granule loss in gutters after any hail event — significant granule loss means the shingles need replacement
• Photograph your roof condition now for insurance documentation

Window Protection

Hail and wind-driven debris can break windows. If you’re in an area that frequently sees severe hail, consider impact-resistant window film as a cost-effective retrofit ($8–$14 per square foot installed). For existing windows, keep interior window coverings down during severe storms to contain glass if a window breaks. Know which windows are most exposed to approaching storm directions (typically south and west).

Outdoor Furniture and Trees

Wind damage from spring storms often comes from unsecured outdoor items becoming projectiles. Before any severe weather watch, bring in or secure patio furniture, potted plants, grills, and decorations. Have large trees near the house inspected by an arborist — dead branches over the roof are a serious risk. Houston’s clay soil can cause tree uprooting in saturated conditions, especially for shallow-rooted species like live oak.

Garage Door Reinforcement

Garage doors are often the weakest structural element of a home during high winds. An unbraced garage door can fail in 60+ mph winds, allowing wind pressure to build inside the structure and potentially lift the roof. Horizontal bracing kits ($50–$150) significantly improve single-layer door strength. For maximum protection, hurricane-rated garage doors provide the best defense in Houston’s severe weather environment.

Emergency Storm Kit Update

Check and refresh your home emergency kit before storm season: rotate food and water supplies, check battery dates, ensure you have a weather radio or NOAA alert-capable phone app, and verify your family’s emergency meeting place and communication plan.
