Popping noises may sound like they are coming from walls when the sounds are actually traveling down the air ducts throughout the house. The popping can sound rather loud as warm air expands or cool air shrinks the metal ductwork, causing them to pop.
Similarly, why does my roof make popping sounds? It's thermal expansion and contraction. The sun hits your roof and heats it up. As the lumber expands, it moves and it will rub against other pieces of wood that aren't moving at the same rate. This movement creates the popping noise.
