Texas Weather That Changed Roofing, Part 5:
The 1983 Hurricane Alicia, Flying Gravel Missiles, and the Dawn of Modern Building Envelope Codes 1983 downtown Houston street scene after Alicia with glass debris.

Texas Weather that Changed Roofing, Part 4
The 1970 Lubbock Tornado, the Fujita Scale, and the Birth of Wind Science When Texans discuss severe weather, coastal hurricanes and sudden flash floods often dominate the conversation.

When Water Turns Against You
Why Winter Weather Can Be Just as Destructive as Hail in North Texas When North Texans think about roof damage, one word dominates the conversation. Let's all say it together: "Hail." And for good reason! Hailstorms can shred shingles in minutes, dent flashing, and leave visible scars across entire neighborhoods.
