How does American Original hold up in high wind conditions?
Most shake and scallop products are rated to wind resistance up to 160 MPH. In independent ASTM testing, American Original stays secure at over 200 MPH wind velocity. This increase in performance is due to our premium composite polypropylene material and advanced product design including our SignalSlots™ nail hem, which allows for nailing every sixteen inches with or without a nail-based sheathing. This makes American Original an excellent choice for areas where hurricanes or storms are a concern.
