If the building envelope is breached through a broken window or loose door, wind pressure will enter the building causing a very sudden and formidable increase in pressure. The positive pressure coming in adds to the stress on the structure where the negative is pulling at the structure. The sudden punch from all that additional air pressure, the sudden punch of positive force added to the existing negative force, will tear apart the weakest part of the building. On a Concrete Block Structured home, the weakest part is the roof. It gets torn apart piece by piece. This is also known as a CBS house. As the building is torn apart from the inside out the wind may push out other windows and walls. By the time the all clear is called, you may not have a habitable home in which to live.
Wood Frame building fare much poorer. Since we know the sudden punch of positive force added to the existing negative force will tear apart the weakest part of the building. Understand how Wood Frame houses are constructed. The roof may go but the walls will likely go first. Wood Frame houses tend to suffer total collapse once the building envelope is breached
