An earthquake can cause a roof to shift and dislodge its heavy shake and tile shingles. This can create a danger of falling debris. When an earthquake shakes the frame of the house and the roofing materials are heavy enough, then some of the framing parts can dislodge, causing a partial or total roof collapse. Many houses, after going through an earthquake have been left flattened or partially destroyed because heavy roofs have caused too much stress on the structure.
During an earthquake, the Roser Roofing System exhibits the best performance when compared to other roofing materials. Weighing in at only 1.4 pounds per square foot, Roser places minimal stress on the house frame. Additionally, the interlocking panel system reinforces the house structure.
