When the outer shell of a house is damaged, it becomes prone to sudden collapse. For example, if a door facing the wind blows in, the full force of the storm will hit the interior. Needing somewhere to go, the wind will then rip out windows, doors, walls or the roof. Even a small breach such as a roof tile bursting through a window, can have the same effect. Therefore pay special attention to all exterior openings.
Storms often get a finger into the house through the roof if it not secure. The wind begins to peel away the roofing material at the gable ends or eaves, exposing the edges of the roof sheathing. The sheathing then becomes damaged and the ceiling gets soaked and collapses, allowing wind and water inside. While the structure may survive, the interior and its contents will likely be destroyed.
