I recently finished reading the book “Ten Seconds Inside a Tornado” by TV resident Ed Frederick, whose vinyl sided home was destroyed by the 2007 Tornado (160mph rotational speed). From the many accounts told in this book, although the walls of block homes withstood the force of the winds, their roofs were torn off just like the frame homes. And this resulted in a lot of flood damage from the penetrating rains.
But more importantly, the majority of the hundreds of injuries were from the shrapnel like debris being hurled through the windows and patio sliders of the homes that were in the direct path of the tornado. And in this regard, block vs. frame didn’t matter.
